Introduction  
Getting Started  
The most widely used portable speakers ever;  
the all-new SRM450 and SRM350 deliver the  
unparalleled ease-of-use, professional sound quality  
and indestructible portability that made SRM a live  
sound legend. Now packed with 1000W of power, the  
widest selection of truly useful sound-enhancing DSP  
and setup-friendly audio tools, SRM is ready for your  
high-output application.  
The following steps will help you set up the  
loudspeakers quickly.  
1. Make all initial connections with the power  
switches OFF on all equipment. Make sure the master  
volume, level, or gain controls are all the way down.  
2. Connect the line-level outputs from the mixing  
console (or other signal source) to the inputs on the  
rear panel of the SRM350v3 / SRM450v3 loudspeakers.  
SRMs feature modern tools like application-specific  
speaker modes and an automatic feedback destroyer,  
each with a single-button interface that gets you  
optimized performance in just seconds. And with  
the integrated 2-channel mixer, you can easily mix  
multiple sources.  
3. Make sure that the loudspeaker’s gain knobs are set  
to (or near) “line”.  
4. Connect the supplied AC power cords to the  
IEC sockets on the rear panel of each loudspeaker.  
Plug the other end into an AC outlet properly configured  
with the correct voltage as indicated below the IEC  
socket.  
Only SRMs deliver this level of power and sound  
quality in such an indestructible, portable package.  
5. Turn the mixer (or other signal source) on.  
6. Turn the loudspeakers on.  
How to Use This Manual:  
7. Start the signal source and raise the mixer’s  
main L/R fader up until audio may be heard  
through the loudspeakers.  
After this introduction, a getting started guide  
will help you get things set up fast. The hookup  
diagrams show some typical setups, while the  
remaining sections provide details of the SRM350v3  
and SRM450v3 loudspeakers.  
8. Adjust the master volume of the mixer to a  
comfortably loud listening level.  
9. Read the rest of this manual to learn how to set the  
speaker mode and feedback destroyer to really dial in a  
sound for the venue.  
This icon marks information that is critically  
important or unique to the loudspeakers.  
For your own good, read and remember them.  
Things to Remember:  
• Never listen to loud music for prolonged periods.  
Please see the Safety Instructions on page 2 for  
information on hearing protection.  
• As a general guide, SRMv3 loudspeakers should  
be turned on last, after any mixer or other signal  
source. As such, they should also be turned off  
first. This will reduce the possibility of any turn-on  
or turn-off thumps and other noises generated  
by any upstream equipment from coming out of  
the speakers.  
Please write your serial number here for future  
reference (i.e., insurance claims, tech support,  
return authorization, make dad proud, etc.)  
Purchased at:  
• Save the shipping boxes and packing materials!  
You may need them someday. Besides, the  
cats will love playing in them and jumping out at  
you unexpectedly. Remember to pretend like you  
are surprised!  
Date of purchase:  
• Save your sales receipt in a safe place.

SRMv3 loudspeakers are the perfect tool for singer-songwriters touring the local coffee shops.  
Bring your favorite axe and mic, SRMv3 loudspeakers and cables and power cords.  
In this example, a dynamic microphone is connected to the channel 1 input of an SRM350v3  
loudspeaker, used for monitoring purposes. Be sure that the gain knob is set to “mic” in order to  
get an extra boost for the mic. If anything other than a microphone is attached to a channel input,  
make sure the gain knob is set to anything other than “mic” [“line” is a safe bet]. From there,  
adjust the gain as described on page 10.  
Now grab your axe and plug it directly into the channel 2 input. Or if you use effects, connect  
the guitar to the effects input and another cable from the effects output to the channel 2 input.  
Set the channel two gain knob to “line”.  
An SRM450v3 loudspeaker will be used for the main PA. Simply connect a cable from the SRM350v3  
loudspeakers THRU jack to the SRM450v3 loudspeakers channel 1 input [gain knob set to “line”].  
Also, make sure the Ch 1/Mix switch is down on the main SRM350v3, as well, so a mix of the  
vocals and guitar is relayed to the PA.  
For the output, you will want to set a speaker mode, described in detail on page 11. For this type of  
setup, PA works well for the main SRM450v3. However, don’t count out the soloist mode! It has a nice  
low cut and a brilliant high end. Select the monitor mode for the SRM350v3 monitor. Lastly, you can ring  
out before you play, utilizing the SRMv3s feedback destroyer [page 11] or just let it kill the feedback  
while playing.

In this example, an SRM1850 subwoofer and additional SRM450v3 loudspeaker have been added  
to the mix, giving our sound system some extra beef. It is a perfect setup for a small club.  
Here, the L/R outputs of a ProFX8 mixer are connected directly to the channel A and B inputs of a single  
SRM1850 subwoofer. Set the gain to “U”.  
The channel A and B high pass outputs of the SRM1850 subwoofer are connected directly to the channel  
1 inputs of each SRM450v3 loudspeaker. Be sure that the gain knob on each is set to “line”. Select the  
VAR high pass mode on the SRM1850 and turn the adjacent knob to120 Hz for a matched system.  
SRMv3 loudspeakers are also perfect for use as stage monitors. Simply connect a cable from each aux  
send to the channel 1 input of each SRMv3 loudspeaker used as a monitor. Its a good idea to use the  
Feedback Destroyer here.  
For the output, you will want to set a speaker mode, described in detail on page 11. For this type  
of setup, we recommend selecting the PA speaker mode for live sound on your SRMv3 loudspeakers.  
If using any SRMv3 loudspeakers as monitors, select the monitor speaker mode.

SRMv3 loudspeakers may be daisy-chained via the male XLR connector labeled “THRU”. Simply plug the  
signal source (i.e., mixer output) into the input jack(s), and patch that loudspeakers THRU jack to the  
next loudspeakers input jack, and so on, daisy-chaining multiple SRMv3 loudspeakers. Make sure that  
the Ch 1 / Mix button is OUT [Ch 1]. See above for visual representations of daisy-chaining.

Heres how to set up a large club system. In this example, the L/R outputs of a DL1608 mixer are  
connected directly to the channel A inputs of two SRM1850 subwoofers. The channel A full range  
outputs of these two SRM1850 subwoofers are connected directly to the channel A inputs of another  
set of SRM1850 subwoofers. Talk about beefy low end...and we’ve only connected the subs!  
The channel A high pass outputs of the last two SRM1850 subwoofers are connected directly to the  
channel 1 inputs of the main pair of SRM450v3 loudspeakers. Be sure that the gain knob on each  
is set to “line”. Select the VAR high pass mode on the SRM1850 and turn the adjacent knob to120 Hz  
for a matched system.  
SRMv3 loudspeakers are also perfect for using as stage monitors. Simply connect a cable from an aux  
send to the channel 1 input of an SRM350v3 loudspeaker. Here you will want to set a speaker mode,  
described in detail on page 11. Since these are monitors, select the appropriately named monitor  
speaker mode.  
Select PA speaker mode for the main loudspeakers. You may also turn the feedback eliminator ON  
on all four SRMv3 loudspeakers, if desired.

As a general guide, SRMv3 loudspeakers  
should be turned on last, after any mixer  
or other signal source. As such, they should  
also be turned off first. This will reduce the possibility  
of any turn-on or turn-off thumps and other noises  
generated by any upstream equipment from coming  
out of the speakers.

level to a line-level signal such as from a mixer. Simply  
connect an XLR, TRS or TS connector into the channel  
and adjust the gain accordingly.

Balanced XLR Input Connector  
To connect balanced lines to these inputs, use a  
1/4" Tip-Ring-Sleeve (TRS) plug. “TRS” stands for  
Tip-Ring-Sleeve, the three connection points  
available on a stereo 1/4" or balanced phone jack  
or plug. TRS jacks and plugs are used for balanced  
signals and stereo headphones and are wired as follows  
according to standards specified by the AES (Audio  
Engineering Society):  
2.Power Switch  
Press the top of this rocker switch inwards to turn  
on the loudspeaker. The front panel LED will glow

plugged into a suitable live AC mains supply and the  
main LED switch [10] is disengaged.  
Press the bottom of this rocker switch inwards to turn  
off the loudspeaker.

4. Gain Knobs  
The gain knobs adjust the input sensitivity of the  
mic, line and/or RCA inputs. This allows signals from  
the outside world to be adjusted to run through each  
channel at optimal internal operating levels.  
6. Thru Output  
This is a male XLR-type connector that produces  
exactly the same signal that is connected to the  
main input jack or a mix of channels 1 and 2. Use it to  
daisy-chain several SRM loudspeakers together off  
the same signal source(s).  
There is – dB of gain with the knob fully down  
(off), ramping up to 50 dB of gain fully up (max).  
The accompanying LED will illuminate green when  
the channel’s input signal is present, indicating signal.  
It will remain lit so long as there is signal above  
–20 dBu present in that channel.  
They are wired as follows, according to standards  
specified by the AES (Audio Engineering Society):  
Balanced XLR Output Connector  
The accompanying LED will illuminate red when the  
amplifier in the SRMv3 loudspeaker is near the clipping  
point. It is okay if this LED blinks occasionally, because  
this means that the transient peaks are just reaching  
the maximum output of the amplifiers and you are  
getting the most out of your loudspeaker.

illuminates when this switch is disengaged and  
AC power is available at the mains input [1].  
Engage the switch if you do not want the front panel  
LED to illuminate.  
SRMv3 loudspeakers have a built-in limiter that  
helps to prevent the amplifier outputs from clipping  
or overdriving the transducers. The limit indicator  
illuminates yellow when the limiter is activated.  
It’s okay for it to blink yellow occasionally, but if it  
blinks frequently or lights continuously, turn down  
the gain knob [4] until it only blinks occasionally.  
PA Speaker Mode – This mode is full range, but  
focuses on mid-range clarity where vocals often reside.  
This is the place to start for most sound reinforcement  
applications.  
DJ Speaker Mode – This mode bumps the lows and  
highs with a mild tuck to the mids, perfect for music  
playback.  
Excessive limiting may lead to  
overheating, which in turn trips the  
thermal protect circuitry and interrupts  
the performance. See ‘Thermal Protection’ on  
page 12 for more information.  
MON(itor) Speaker Mode – This mode features a  
low frequency roll-off and a reduction around 2 kHz to  
ensure maximum gain before feedback in monitor  
applications.  
SOLO(ist) Speaker Mode – This mode features  
a low frequency roll-off to get rid of unwanted thumps  
and adds boost and sparkle to mid-range and high  
frequencies. This plug-and-play mode is perfect for  
singer-songwriters.  
11. Breakfast Mode  
Breakfast is the most important meal of the day.  
Here you are able to order your favorite breakfast  
food and drink. Press the breakfast mode buttons  
repeatedly until the LEDs of the food and drink you  
desire are illuminated. This mode is only available  
between 6 am and 11 am at participating SRMv3  
loudspeakers.  
9. Feedback desTROYer:  
The multi-band feedback destroyer hunts down  
offending feedback frequencies and applies up to four  
notch filters automatically to destroy feedback and  
maximize gain prior to feedback. This is a great tool  
for performers without a dedicated engineer.  
The integrated and amazingly accurate Feedback  
Destroyer instantly employs up to four incredibly  
narrow 1/16th octave filters to locate and eradicate  
feedback so you know you can perform fearlessly.  
Plus, the entire system is protected by our Smart  
ProtectDSP which kicks in to protect your  
investment when things get pushed a little too hard.

Smart Protect  
There are advanced DSP protection mechanisms  
designed into the SRM350v3 and SRM450v3  
to safeguard the loudspeakers and amplifiers  
from inadvertent damage.  
AC Power  
Be sure the SRMv3 loudspeaker is plugged into an  
outlet that is able to supply the correct voltage specified  
for your model. It will continue to operate at lower  
voltages, but will not reach full power.  
The protection circuits are designed to  
protect the loudspeakers under reasonable  
and sensible conditions. Should you choose  
to ignore the warning signs [e.g. excessive distortion],  
you can still damage the speaker by overdriving it past  
the point of amplifier clipping. Such damage is beyond  
the scope of the warranty.  
Be sure the electrical service can supply enough  
amperage for all the components connected to it.  
We recommend that a stiff (robust) supply of AC  
power be used because the amplifiers place high  
current demands on the AC line. The more power that is  
available on the line, the louder the speakers will play  
and the more peak output power will be available for a  
cleaner, punchier bass. A suspected problem of “poor  
bass performance” is often caused by a weak AC supply  
to the amplifiers.  
Limiting  
Each driver has its own compression circuit which  
helps protect it from damaging transient peaks.  
The compressor is designed to be transparent and  
is not noticeable under normal operating conditions.  
Never remove the ground pin on the power  
cord or any other component of the SRMv3  
loudspeaker. This is very dangerous.  
Overexcursion Protection  
An 18 dB/octave high-pass filter just prior to the  
low-frequency amplifier prevents very low frequencies  
from being amplified. Excessive low-frequency energy  
can damage the woofer by causing it to “bottom out,”  
also know as overexcursion, which is equivalent to a  
mechanical form of clipping.  
Care and Maintenance  
SRMv3 loudspeakers will provide many years  
of reliable service if you follow these guidelines:  
Avoid exposing the loudspeakers to moisture.  
If they are set up outdoors, be sure they are  
under cover if rain is expected.  
Thermal Protection  
Avoid exposure to extreme cold (below  
freezing temperatures). If you must operate  
the loudspeakers in a cold environment, warm  
up the voice coils slowly by sending a low-level  
signal through them for about 15 minutes prior  
to high-power operation.  
All amplifiers produce heat. SRMv3 loudspeakers are  
designed to be efficient both electrically and thermally.  
In the unlikely event of the amplifier overheating,  
a built-in thermal switch will activate, muting the  
signal.  
Use a dry cloth to clean the cabinets. Only do  
this when the power is turned off. Avoid getting  
moisture into any of the openings of the  
cabinet, particularly where the drivers are  
located.  
When the amplifier has cooled down to a safe  
operating temperature, the thermal switch resets itself,  
and the SRMv3 loudspeaker resumes normal operation.  
If the thermal switch activates, try turning down the  
level control a notch or two on the mixing console (or  
the back of the loudspeaker) to avoid overheating the  
amplifier. Be aware that direct sunlight and/or hot stage  
lights may be the culprit of an amplifier overheating.

Placement  
WARNING: Installation should only be done  
SRMv3 loudspeakers are NOT designed to array  
horizontally. If you feel you must put two speakers  
side-by-side, you should have a good understanding  
of the relationship between the splay angle (the angle  
between the facing sides of the cabinets) and frequency  
cancellation effects between cabinets.  
by an experienced technician. Improper  
installation may result in damage to the  
equipment, injury or death. Make sure that the  
loudspeaker is installed in a stable and secure way  
in order to avoid any conditions that may be dangerous  
for persons or structures.  
When two cabinets are positioned side-by-side  
such that the rear-angled faces of the enclosures  
are parallel, the splay angle will be 90º. This matches  
the 90˚ horizontal coverage pattern of each individual  
SRMv3 loudspeakers are designed to sit on the floor  
or stage as the main PA or as monitors. They may also  
be pole-mounted via the built-in socket on the bottom  
of the cabinet. Be sure the pole is capable of supporting loudspeaker; the interference between the two cabinets  
the weight of the loudspeaker. The SPM200 is a great  
option when using a subwoofer.  
will be minimized, but the total coverage of 180˚ may  
be too wide for some applications. The mid and high  
frequencies may also be reduced for those in the center  
who are too close to the loudspeakers.  
These loudspeakers may also be flown via their  
integrated fly points as detailed on page 15. Be sure  
to read the PA-A1 Eyebolt Installation Instructions,  
as well.  
Reducing the splay angle will reduce the total  
horizontal coverage, but it also creates an area both  
speakers are covering. Instead of a nearfield hole,  
this will cause comb-filtering effects in the frequency  
response in the overlapping area. The smaller the splay  
angle, the more energy will be delivered on-axis, but the  
comb-filtering effects will get worse at the same time.  
Check to make sure that the support surface  
(e.g. floor, etc.) has the necessary mechanical  
characteristics to support the weight of the  
loudspeaker(s).  
When pole-mounting loudspeakers, be sure that they  
are stabilized and secured from falling over or being  
accidentally pushed over. Failure to follow these  
precautions may result in damage to the equipment,  
personal injury, or death.  
To reiterate, though, we strongly suggest  
NOT arraying these loudspeakers horizontally.  
Experimentation and experience will help you find  
the right balance for your application.  
As with any powered components, protect them from  
moisture. Avoid installing the loudspeaker in places  
exposed to harsh weather conditions. If you are setting  
them up outdoors, make sure they are under cover if you  
expect rain.

Room Acoustics  
SRMv3 loudspeakers are designed to sound fantastic  
in nearly every application.  
Position the loudspeakers so the high-  
frequency drivers are two to four feet above  
ear level for the audience (making allowances  
for an audience that may be standing/dancing  
in the aisles). High frequencies are highly  
directional and tend to be absorbed much  
easier than lower frequencies. By providing  
direct line-of-sight from the loudspeakers  
to the audience, you increase the overall  
brightness and intelligibility of the sound  
system.  
But, room acoustics play a crucial role in the overall  
performance of a sound system. However, the wide  
high-frequency dispersion of the SRMv3 loudspeakers  
helps to minimize the problems that typically arise.  
Top  
Highly reverberant rooms, like many  
gymnasiums and auditoriums, are a  
nightmare for sound system intelligibility.  
Multiple reflections off the hard walls, ceiling,  
and floor play havoc with the sound. Depending  
on the situation, you may be able to take some  
steps to minimize the reflections, such as  
putting carpeting on the floors, closing  
draperies to cover large glass windows, or  
hanging tapestries or other materials on the  
walls to absorb some of the sound.  
0
90  
0
90 Dispersion  
up to 20 kHz  
However, in most cases, these remedies are not  
possible or practical. So what do you do?  
Making the sound system louder generally  
doesn’t work because the reflections become  
louder, too. The best approach is to provide as  
much direct sound coverage to the audience  
as possible. The farther away you are from  
the speaker, the more prominent will be the  
reflected sound.  
Here are some additional placement tips to help  
overcome some typical room problems that might arise:  
Placing loudspeakers in the corners of a room  
increases the low frequency output and can  
cause the sound to be muddy and indistinct.  
Placing loudspeakers against a wall increases  
the low frequency output, though not as much  
as corner placement. However, this is a good  
way to reinforce the low frequencies, if so  
desired.  
Use more speakers strategically placed so they  
are closer to the back of the audience. If the  
distance between the front and back speakers  
is more than about 100 feet, you should use a  
delay processor to time-align the sound. (Since  
sound travels about 1 foot per millisecond, it  
takes about 1/10 of a second to travel 100 feet.)  
Avoid placing the speakers directly on a  
hollow stage floor. A hollow stage can resonate  
at certain frequencies, causing peaks and dips  
in the frequency response of the room. It is  
better to place them on a sturdy stand designed  
to handle the weight of the loudspeaker.  
Keep in mind that the speaker mode and feedback  
destroyer are two great ways to compensate for some of  
these issues. See page 11 for more information [8, 9].

Rigging Hardware and Accessories  
Rigging  
Rigging our loudspeakers will invariably require  
hardware not supplied by us. Various types of  
WARNING: Installation should only be done  
by an experienced technician. Improper  
installation may result in damage to the  
equipment, injury or death. Make sure that the  
loudspeaker is installed in a stable and secure way  
in order to avoid any conditions that may be dangerous  
for persons or structures.  
load-rated hardware are available from a variety  
of third-party sources. There are a number of such  
companies specializing in manufacturing hardware  
for, designing, and installing rigging systems. Each  
one of these tasks is a discipline in its own right.  
Because of the hazardous nature of rigging work  
and the potential liability, engage companies that  
specialize in these disciplines to do the work required.  
WARNING: The cabinet is suitable for rigging  
via its fly points. NEVER attempt to suspend  
an SRMv3 loudspeaker by its handle.  
We do offer certain accessory rigging items and some  
of them may be used with a variety of products. While  
these accessories are intended to facilitate installation,  
the wide variety of possible installation conditions and  
array configurations do not permit us to determine their  
suitability or load rating for any particular application.  
Rigging Design Practices  
Rigging a loudspeaker requires determining:  
1. The rigging methods and hardware that meet static,  
shock, dynamic, and any other load requirements for  
supporting the loudspeaker from structure.  
We are not in the business of providing complete  
rigging systems, either as designers, manufacturers,  
or installers. It is the responsibility of the installer to  
provide a properly engineered, load-certified rigging  
system for supporting the loudspeaker from structure.  
2. The design factor and required WLL (Working Load  
Limit) for this support.  
We strongly recommend the following rigging practices:  
SRMv3 loudspeakers may be individually flown  
using a PA-A1 Eyebolt Kit, part number  
0031943. SRM350v3 cabinets are fitted  
1. Documentation: Thoroughly document the design  
with detailed drawings and parts lists.  
with four M5 insert points on the top and bottom for  
installing an optional hanging bracket that allows the  
speaker to be flown. SRM350v3 Bracket Kit: PN 0016404  
2. Analysis: Have a qualified professional, such as a  
licensed Professional Engineer, review and approve the  
design before its implementation.  
3. Installation: Have a qualified professional rigger do  
the installation and inspection.  
Rigging Notes  
4. Safety: Use adequate safety precautions and  
back-up systems.  
The SRMv3 loudspeaker’s integral mounting points  
are designed to support only the weight of their own  
loudspeaker with suitable, external hardware. This  
means that each SRMv3 loudspeaker must be supported  
independently of any other SRMv3 loudspeaker and any  
other loads. All rigging points must be used to hang an  
SRMv3 loudspeaker.

Appendix A: Service Information  
If you think the SRMv3 loudspeaker has a problem,  
please check out the following troubleshooting tips and  
do your best to confirm the problem. Visit the Support  
will find lots of useful information such as FAQs and  
other documentation. You may find the answer to the  
problem without having to part with your loudspeaker.  
Poor sound  
• Is it loud and distorted? Make sure that you’re not  
overdriving a stage in the signal chain. Verify that  
all level controls are set properly.  
• Is the input connector plugged completely into  
the jack? Be sure all connections are secure.  
Noise  
Troubleshooting  
• What is the position of the gain knob? It should  
be at (or near) “mic” when a mic is connected  
and at (or near) “line” when a line-level signal  
is connected. It should be “off” for all unused  
inputs.  
• Make sure all connections to the active  
loudspeakers are good and sound.  
• Make sure none of the signal cables are routed  
near AC cables, power transformers, or other  
EMI-inducing devices.  
No power  
• Our favorite question: Is it plugged in? Make sure  
the AC outlet is live [check with a tester or lamp].  
• Our next favorite question: Is the power switch  
on? If not, try turning it on.  
• Is the LED on the front panel illuminated?  
If not, make sure the AC outlet is live.  
If so, refer to “No sound” below.  
• The internal AC line fuse may be blown. This is  
not a user serviceable part. If you suspect the  
AC line fuse is blown, please see the "Repair"  
section next.  
• Is there a light dimmer or other SCR-based device  
on the same AC circuit as the SRM loudspeaker?  
Use an AC line filter or plug the loudspeaker into  
a different AC circuit.  
No sound  
Hum  
• Is the input gain knob for the input source  
turned all the way down? Verify that all the gain  
knobs in the system are properly adjusted. Look  
at the level meter to ensure that the mixer is  
receiving a signal.  
• Is the signal source working? Make sure the  
connecting cables are in good repair and securely  
connected at both ends. Make sure the output  
level control on the mixing console is turned up  
sufficiently to drive the inputs of the speaker.  
• Make sure the mixer does not have a mute on or a  
processor loop engaged. If you find something like  
this, make sure the level is turned down before  
disengaging the offending switch.  
• Try disconnecting the cable connected to the main  
input jack. If the noise disappears, it could be  
a “ground loop,” rather than a problem with the  
SRMv3 loudspeaker. Try some of the following  
troubleshooting ideas:  
• Use balanced connections throughout your system  
for the best noise rejection.  
• Whenever possible, plug all the audio equipment’s  
line cords into outlets which share a common  
ground. The distance between the outlets and the  
common ground should be as short as possible.  
Repair  
• Has it shut down? Make sure there is at least  
six inches of free space behind each SRMv3  
loudspeaker.  
For warranty service, refer to the warranty  
information on page 23.  
Non-warranty service is available at a factory-  
authorized service center. To locate the nearest  
Tech Support” and select “Locate a Service Center  
or Distributor” [3]. Service for SRMv3 loudspeakers  
living outside the United States can be obtained  
through local dealers or distributors.  
Poor bass performance  
• Check the polarity of the connections between the  
mixer and the loudspeakers. You may have your  
positive and negative connections reversed at one  
end of one cable, causing one loudspeaker to be  
out-of-phase with the other.  
• Poor bass performance may be the result of bad  
AC power. See the section titled ‘AC Power’ on  
page 12 for further details.  
If you do not have access to our website, you may call  
the Tech Support department at 1-800-898-3211,  
Monday-Friday, during normal business hours, Pacific  
Time, to explain the problem. Tech Support will tell you  
where the nearest factory-authorized service center is  
located in your area.
