Installation  
This Lowrance radio is designed to generate a digital maritime distress call to facilitate search  
and rescue. To be effective as a safety device, this radio must be used only within the geo-  
graphic range of a shore-based VHF marine Channel 70 distress and safety watch system. The  
geographic range may vary but under normal conditions is approximately 20 nautical miles.  
Installation Options  
There are two ways to install the radio. You can choose:  
A deck or overhead mounted gimbal installation. The reversible mounting gimbal is fixed  
to a suitable site and the radio is placed into it. The radio can be removed for storage and  
the viewing angle can be adjusted.  
A recessed installation. The radio is recessed into a cavity cut into a bulkhead. The radio  
fixture is permanent and the viewing angle cannot be adjusted.  
Location Requirements  
Please check these before doing any cutting or drilling.  
Whichever installation method you choose, ensure that the chosen location:  
Is at least 3(1 m) from the antenna  
Allows easy connection to (at least) a 10 Amp fused 13.6 V DC electrical source and the  
antenna  
Is at least 1.5’ (45 cms) from the compass to avoid creating magnetic deviation of the  
compass during radio operation  
Has a suitable space close by for installing the microphone bulkhead mount  
Provides easy access to the controls on the front panel  
Provides reasonable access to the wiring at the  
Side  
back of the radio  
20˚  
Provides enough room to fix the DSC warning  
20˚  
label  
The VHF has a large LCD screen with an optimum  
viewing angle of approx. +/-20 deg. Ensure the  
chosen location provides a suitable view of the  
display. Ideally, the user should be directly in front  
of the display or no more than +/-20 deg from the  
front of the display.

Gimbal Installation  
1. Hold the mounting gimbal at the chosen location and use a soft pencil to mark the  
screw hole positions onto the mounting surface.  
2. If you can’t reach behind the mounting surface to attach the nuts, use the self-tapping  
screws instead of the flat screws shown in the picture. If you’re drilling into fibreglass,  
use a drill bit smaller than 3/16(5mm) to drill the pilot holes.  
Otherwise, drill the four screw holes where marked, using a 3/16(5mm) drill bit. Drill  
completely through the mounting surface.  
3. Use a Philips screwdriver and the set of four flat screws, spring washers, plain washers,  
and nuts to attach the mounting gimbal to the location site.  
4. Slide the radio into the mounting gimbal.  
5. Insert the two mounting knobs through the holes and tighten them sufficiently to hold  
the radio at the desired viewing angle.  
Change the Viewing Angle  
The viewing angle on the gimbal mount has a 20º tilt range. To change the current viewing  
angle on the gimbal mount:  
1. Support the radio, then cautiously loosen the mounting knobs until the radio can be  
moved.  
2. Re-position the radio then tighten the mounting knobs again.  
Recessed Installation  
1. Tape the installation template onto the chosen location site.  
2. Cut out the area marked by the solid dark line. (The dashed line indicates the total area  
8

that will be covered by the radio fascia after installation.) Drill the 4 mounting holes.  
3. Remove the installation template and slide the radio into the cavity.  
4. Screw each M5x32 screw through the screw hole in the mounting bracket, then attach  
the stopper. If your bulkhead exceeds 0.51” (13mm), the stopper can be discarded if  
necessary.  
5. Tighten the M5x32 screws until the radio is held firmly against the rear of the bulkhead.  
Install the Microphone Bulkhead Mount  
ꢀꢁꢂꢃꢄ ꢅꢆꢇꢁꢈ MM  
1. Hold the microphone bulkhead mount at the  
chosen location and use a soft pencil to mark  
the screw hole positions on the mounting  
surface. Ensure that the microphone curly cable will  
comfortably reach this location BEFORE you drill.  
2. Drill the two pilot screw holes where marked.  
3. Use a short length Philips screwdriver and the  
set of two flat screws, spring washers, plain  
washers, and nuts to secure the microphone  
bulkhead mount at the location site.  
4. Hang the microphone on its mount.

Fix the DSC label  
CAUTION  
A DSC warning label is supplied with the LVR-250. To comply with FCC regulations, this  
warning label must be affixed in a location that is clearly visible from the operating con-  
trols of this Lowrance radio. Make sure that the chosen location is clean and dry before  
applying this label.  
Connect the Radio Cables  
The connectors are on the rear of the base unit, as follows:  
1. GPS/COM connector. For connection to GPS device via NMEA. See the following table  
for wiring and color codes. (If you’re not using this, be sure to put the protective cap  
securely over the connector to protect it from moisture and dust.)  
2. External Speaker connector. Plug the external speaker cable jack into the connector  
BEFORE powering on the radio. Use a 4 Ohm 4 Watt external speaker.  
3. Red Power wire. Connect this to the Positive (+) battery terminal. Check that a 10 Amp  
fuse is installed on this power cable close to the battery.  
4. Black Power wire. Connect this to the Negative (-) battery terminal.  
5. ANT. A radio antenna is not supplied. A suitable radio antenna must be mounted  
and connected before operating the LVR-250 radio. Consult your dealer for advice if  
necessary.  
6. GND. A ground connection is not usually required.

CAUTION  
You can’t make any DSC transmissions until you’ve obtained a user MMSI and entered it  
into your LVR-250.  
The user MMSI is a unique nine digit number, similar to a personal telephone number. It is  
used on marine transceivers that are capable of using DSC (Digital Select Calling).  
If you don’t have a user MMSI contact the appropriate authorities in your country. If you’re  
unsure who to contact, consult your Lowrance dealer.  
Enter Your User MMSI  
Refer to 4.2 Enter your user MMSI.

time Organization) and is part of the GMDSS (Global Maritime Distress and Safety System).  
Currently, you are required to monitor Distress Channel 16, but DSC will eventually replace  
listening watches on distress frequencies and will be used to broadcast routine and urgent  
maritime safety information.  
DSC enables you to send and receive calls from any vessel or coast station that is equipped  
with DSC functionality, and within geographic range. Calls can be categorised as distress,  
urgency, safety, or routine, and DSC selects a working channel automatically.

Appendix B - Troubleshooting  
1. The transceiver will not power up.  
A fuse may have blown OR there is no voltage getting to the transceiver.  
a. Check the power cable for cuts, breaks, or squashed sections.  
b. After checking the wiring, replace the 7 Amp fuse (1 spare fuse is supplied).  
c. Check the battery voltage. This must be greater than 10.5V.  
2. The transceiver blows the fuse when the power is switched on.  
The power wires may have been reversed.  
a. Check that the red wire is connected to the positive battery terminal, and the black  
wire is connected to the negative battery terminal.  
3. The speaker makes popping or whining noises when the engine is running.  
Electrical noise may be interfering with the transceiver.  
a. Re-route the power cables away from the engine.  
b. Add a noise suppressor to the power cable.  
c. Use resistive spark plug wires and/or use an alternator whine filter.  
4. No sound from the external speaker.  
a. Check that the external speaker cable is physically connected.  
b. Check the soldering of the external speaker cable.  
5. Transmissions are always on low power, even when high (HI) power is selected.  
The antenna may be faulty.  
a. Test the transceiver with a different antenna.  
b. Have the antenna checked out.  
6. Battery symbol is displayed.  
The power supply is too low or too high.  
a. Check the battery voltage. This should be at least 10.5V 0.5V DC.  
b. Check the alternator on the vessel.  
7. No position information is displayed.  
The GPS cable may faulty or the GPS setting may be incorrect.  
a. Check that the GPS cable is physically connected.  
b. Check the polarity of the GPS cable.  
c. Check the baud rate setting of the GPS if applicable. The baud rate setting should be 4800 and  
parity should be set to NONE.
