Precautions  
1. Recording Copyright—Unless it’s for personal use  
only, recording copyrighted material is illegal with-  
out the permission of the copyright holder.  
• Do not expose this unit to direct sunlight or heat  
sources, because its internal temperature may  
rise, shortening the life of the optical pickup.  
• Avoid damp and dusty places, and places subject  
to vibrations from loudspeakers. Never put the  
unit on top of, or directly above a loudspeaker.  
• Install this unit horizontally. Never use it on its  
side or on a sloping surface, because it may cause  
a malfunction.  
• If you install this unit near a TV, radio, or VCR,  
the picture and sound quality may be affected. If  
this occurs, move this unit away from the TV,  
radio, or VCR.  
2. AC Fuse—The AC fuse inside the unit is not user-  
serviceable. If you cannot turn on the unit, contact  
your Onkyo dealer.  
3. Care—Occasionally you should dust the unit all  
over with a soft cloth. For stubborn stains, use a soft  
cloth dampened with a weak solution of mild deter-  
gent and water. Dry the unit immediately afterwards  
with a clean cloth. Don’t use abrasive cloths, thin-  
ners, alcohol, or other chemical solvents, because  
they may damage the finish or remove the panel let-  
tering.  
8. To Obtain a Clear Picture—This unit is a high-  
tech, precision device. If the lens on the optical  
pickup, or the disc drive mechanism becomes dirty  
or worn, the picture quality may be affected. To  
maintain the best picture quality, we recommend  
regular inspection and maintenance (cleaning or  
worn part replacement) every 1,000 hours of use  
depending on the operating environment. Contact  
your Onkyo dealer for details.  
4. Power

place.  
The power cord plug is used to disconnect this unit  
from the AC power source. Make sure that the plug  
is readily operable (easily accessible) at all times.  
Pressing the [STANDBY/ON] button to select  
Standby mode does not fully shutdown the unit. If  
you do not intend to use the unit for an extended  
period, remove the power cord from the AC outlet.  
5. Never Touch this Unit with Wet Hands—Never  
handle this unit or its power cord while your hands  
are wet or damp. If water or any other liquid gets  
inside this unit, have it checked by your Onkyo  
dealer.  
– A heater is turned on, or cold air from an air  
conditioner is hitting the unit.  
– In the summer, when this unit is moved from  
an air conditioned room to a hot and humid  
place.  
6. Handling Notes  
– The unit is used in a humid place.  
• Do not use this unit when there’s the possibility  
of moisture condensation occurring. Doing so  
may damage your discs and certain parts inside  
this unit.  
If condensation does occur, remove all discs and  
leave this unit turned on for two to three hours. By  
this time, the unit will have warmed up and any con-  
densation will have evaporated.  
• If you need to transport this unit, use the original  
packaging to pack it how it was when you origi-  
nally bought it.  
• Do not leave rubber or plastic items on this unit  
for a long time, because they may leave marks on  
the case.  
• This unit’s top and rear panels may get warm  
after prolonged use. This is normal.  
• If you do not use this unit for a long time, it may  
not work properly the next time you turn it on, so  
be sure to use it occasionally.  
• When you’ve finished using this unit, remove all  
discs and turn off the power.  
7. Installing this Unit  
• Install this unit in a well-ventilated location.

Insert two batteries (R6/AA) into the bat-  
tery compartment.  
2
Carefully follow the polarity diagram (positive  
(+) and negative (–) symbols) inside the battery  
compartment.  
Notes:  
• The remote controller may not work reliably if the CD  
receiver is subjected to bright light, such as direct sun-  
light or inverter-type fluorescent lights. Keep this in mind  
when installing.  
• If another remote controller of the same type is used in  
the same room, or the CD receiver is installed close to  
equipment that uses infrared rays, the remote controller  
may not work reliably.  
• Don’t put anything, such as a book, on the remote con-  
troller because the buttons may be pressed inadvertently,  
thereby draining the batteries.  
• The remote controller may not work reliably if the CD  
receiver is installed in a rack behind colored glass doors.  
Keep this in mind when installing.  
• The remote controller will not work if there’s an obstacle  
between it and the CD receiver’s remote control sensor.  
After the batteries are installed and  
seated correctly, attach the compartment  
cover.

Notes:  
• If the remote controller doesn’t work reliably, try replac-  
ing the batteries.  
• Don’t mix new and old batteries or different types of bat-  
teries.  
• If you intend not to use the remote controller for a long  
time, remove the batteries to prevent damage from leak-  
age or corrosion.  
• Expired batteries should be removed as soon as possible  
to prevent damage from leakage or corrosion.

Connecting Antennas  
This section explains how to connect the supplied indoor  
FM antenna, AM loop antenna, and DAB antenna, and  
how to connect commercially available outdoor FM and  
AM antennas.  
Connecting the AM Loop Antenna  
The supplied indoor AM loop antenna is for indoor use  
only.  
The CD receiver won’t pick up any radio signals without  
an antenna connected, so you must connect the antenna  
to use the tuner.  
Assemble the AM loop antenna, inserting  
the tabs into the base, as shown.  
1
AM ANTENNA push terminals  
FM ANTENNA jack  
Connect both wires of the AM loop  
antenna to the AM ANTENNA push termi-  
nals, as shown.  
2
DAB antenna jack  
(The antenna’s wires are not polarity sensitive, so  
they can be connected either way around).  
Make sure that the wires are attached securely and  
that the push terminals are gripping the bare  
wires, not the insulation.  
Connecting the Indoor FM Antenna  
The supplied indoor FM antenna is for indoor use only.  
Attach the FM antenna, as shown.  
1
Insert the plug fully  
into the jack.  
Push  
Insert wire  
Release  
Once the CD receiver is ready for use, you’ll need  
to tune into an FM radio station and adjust the  
position of the FM antenna to achieve the best  
possible reception.  
Once the CD receiver is ready for use, you’ll need  
to tune into an AM radio station and adjust the  
position of the AM antenna to achieve the best  
possible reception.  
Use thumbtacks or something similar to  
fix the FM antenna into position.  
2
Keep the antenna as far away as possible from the  
CD receiver, TV, speaker cables, and power cords.  
Thumbtacks, etc.  
If you cannot achieve good reception with the supplied  
indoor AM loop antenna, try using it with a commer-  
cially available outdoor AM antenna (see page 18).  
Caution:  
Be careful that you don’t injure yourself when using  
thumbtacks.  
If you cannot achieve good reception with the supplied  
indoor FM antenna, try a commercially available out-  
door FM antenna instead (see page 18).  
17  
       
Connecting the DAB Antenna  
Connecting an Outdoor FM Antenna  
If you cannot achieve good reception with the supplied  
indoor FM antenna, try a commercially available out-  
door FM antenna instead.  
Screw the supplied DAB antenna’s plug  
onto the DAB antenna jack.  
1
Once the CD Receiver is ready for use, you’ll  
need to tune into a DAB station and adjust the  
position of the DAB antenna to achieve the best  
possible reception.  
Notes:  
• Outdoor FM antennas work best outside, but usable  
results can sometimes be obtained when installed in an  
attic or loft.  
• For best results, install the outdoor FM antenna well away  
from tall buildings, preferably with a clear line of sight to  
your local FM transmitter.  
• Outdoor antenna should be located away from possible  
noise sources, such as neon signs, busy roads, etc.  
• For safety reasons, outdoor antenna should be situated  
well away from power lines and other high-voltage  
equipment.  
Use thumbtacks or something similar to  
fix the DAB antenna into position.  
2
• Outdoor antenna must be grounded in accordance with  
local regulations to prevent electrical shock hazards.  
Using a TV/FM Antenna Splitter  
It’s best not to use the same antenna for both FM and TV  
reception, as this can cause interference problems. If cir-  
cumstances demand it, use a TV/FM antenna splitter, as  
shown.  
TV/FM antenna splitter

Connecting an Outdoor AM Antenna  
If good reception cannot be achieved using the supplied  
AM loop antenna, an outdoor AM antenna can be used  
in addition to the loop antenna, as shown.  
Outdoor antenna  
AM loop antenna  
Insulated antenna cable  
Outdoor AM antennas work best when installed horizon-  
tally outside, but good results can sometimes be obtained  
indoors by mounting horizontally above a window. Note  
that the AM loop antenna should be left connected.  
Outdoor antenna must be grounded in accordance with  
local regulations to prevent electrical shock hazards.

Connecting Your Speakers  
• Connect the right speaker to the CD receiver’s right (R) SPEAKERS terminals. Connect the left speaker to the left  
(L) SPEAKERS terminals.  
• Connect the positive (+) terminal on each speaker to the corresponding positive (+) terminal on the CD receiver.  
Connect the negative (–) terminal on each speaker to the corresponding negative (–) terminal on the CD receiver. Use  
the red wires to connect the positive (+) terminals.  
Left speaker  
Right speaker  
Red wires  
—Terminal posts—  
Strip about 15 mm of insulation from the ends of the speaker cables,  
and twist the bare wires tightly. Unscrew the terminal. Fully insert the  
bare wire, making sure that it’s touching the threaded shaft in the center.  
Screw the terminal tight.  
Speaker  
cable  
• Connect only speakers with an impedance of between  
4 and 16 ohms. Connecting a speaker with a lower  
impedance may damage the speaker.  
• Do not connect both speaker cables to the same L or R  
terminals (Fig. 1). Do not connect more than two  
speaker terminals to each speaker (Fig. 2).  
• Be careful not to short the positive and negative wires.  
Doing so may damage the CD receiver.

Using the Timers  
The CD receiver has five timers: four programmable tim-  
ers for automated playback or recording, and a sleep timer  
for turning the CD receiver off after a specified period.  
The timers can be used with other Onkyo components  
that are connected to the CD receiver via u (see pages  
21 to 23 for hookup details).  
Timer Examples  
The following examples highlight some of the ways in  
which you can use the timers.  
Timer 1: To wake up to your favorite radio station  
(preset #1) every morning, set as follows:  
PlayFM 1EveryEvery DayOn  
7:00Off 7:30  
About the Timers  
The various settings for the four programmable timers are  
explained here. For details on the sleep timer, see page 58.  
If you want a radio alarm only on weekdays,  
select “Days Set” instead of “Every Day” and  
specify “MON–FRI”.  
Timer Types  
Timer 2: To record a one-off radio show (preset #2) to

Play mode can be used to start playback at a specified  
time on the CD receiver or another Onkyo component  
that’s connected to the CD receiver with an u cable.  
You could use a Play timer to turn on the CD receiver  
every morning, just like a radio alarm.  
RecFM 1MDEveryDays SetMON➔  
FRIOn 15:00Off 15:30  
Rec  
Rec mode can be used to start playback on one compo-  
nent and start recording on another component at a spec-  
ified time. The recording component (e.g., Onkyo  
cassette deck or MD recorder) must be connected to the  
CD receiver with an u cable. You could use a Rec  
timer to record your favorite radio show every day.  
Timer Priority  
If two or more timers are set to the same On time, the  
lowest numbered timer has priority. For example:  
Timer 1: 07:00 – 13:00 (This timer has priority.)  
Timer 2: 07:00 – 12:30  
Playback and Recording Components  
If two or more timers overlap, the timer with the earliest  
start time has priority. For example:  
The playback component can be the CD receiver (AM,  
FM, DAB or CD), an Onkyo component (MD recorder,  
cassette deck, etc.) that’s connected to the CD receiver  
Timer 1: 9:00 – 10:00  
with an  
u
cable, or a component that’s connected to one  
Timer 2: 8:00 – 10:00 (This timer has priority.)  
If the On and Off times of two timers are the same, the  
timer with the earliest start time has priority and the  
other timer will fail. For example:  
of the CD receiver’s inputs, perhaps one with its own built-  
in timer.  
On the CR-525UKD, it is also possible to play MP3 and  
WMA files from a USB mass storage device that is con-  
nected to the USB port of the CR-525UKD.  
The recording component can be an Onkyo MD recorder  
or cassette deck that’s connected to the CD receiver with  
an u cable.  
Timer 1: 0:00 – 1:00 (This timer has priority.)  
Timer 2: 1:00 – 2:00  
Timer Indicators  
When a timer has been set, the TIMER indica-  
tor and the number of the timer appear on the  
display. If the timer has been set to perform  
recording, an underscore character appears  
underneath the timer’s number.  
Repeat Timers  
Each timer can be programmed to work just once  
(Once), every week (Every), every day (Every Day), or  
on a range of days (Days Set).  
Once  
The timer will work just once.  
Notes:  
• The timers work only if the CD receiver is on Standby. If  
it’s on when a timer is supposed to start playback or  
recording, nothing will happen.  
• While timed playback or recording is in progress, the  
timer’s Off time cannot be changed.  
• To use timed playback or recording with an external com-  
ponent, make sure it’s properly connected to the CD  
receiver. Also, for u to work properly, make sure that  
the Input Display on the CD receiver is set to match the  
type of component you’ve connected to the MD/TAPE IN  
Every  
The timer will work every week on the specified day and  
time.  
Everyday  
The timer will work every day.  
Days Set  
The timer will work on the specified range of days. With  
this setting, you could set up a morning alarm for Mon-  
day to Friday.

STANDBY/ON  
“Clear” will appear on the display and the CD receiver  
will enter Standby mode.  
Power  
Can’t turn on the CD receiver.  
• Make sure that the power cord is properly plugged into the wall outlet (see page 23).  
• Unplug the power cord from the wall outlet, wait 5 seconds or more, then plug it in again.  
The CD receiver turns off unexpectedly.  
• If the sleep timer has been set and the TIMER indicator is shown on the display, the CD receiver will turn off auto-  
matically after a specified period.  
• When timed playback or recording finishes, the CD receiver automatically switches to Standby mode.  
• If the STANDBY indicator is flashing, the built-in amplifier protection circuit has been activated. This can happen if  
there’s a short between the positive and negative wires of a speaker cable.  
Audio  
There’s no sound.  
• Make sure the CD receiver’s volume control is not set to minimum (see page 25).  
• Make sure the correct input source is selected (see page 25).  
• Make sure the CD receiver is not muted (see page 26).  
• Make sure the speakers are connected correctly (see page 19).  
• Check all connections and correct as necessary (see pages 17 to 23).  
• While headphones are connected, the speakers output no sound (see page 25).  
The sound quality is not good.  
• Make sure the speaker cables are connected with the correct polarity (see page 19).  
• Make sure all audio connecting plugs are pushed in all the way (see page 20).  
• The sound quality can be affected by strong magnetic fields, such as that from a TV. Try moving any such devices  
away from the CD receiver.  
• If you have any devices that emit high-intensity radio waves near the CD receiver, such as a cellular phone that’s being  
used to make a call, the CD receiver may output noise.  
• The CD receiver’s precision drive mechanism may emit a faint hissing sound while reading discs during playback or  
when searching for tracks. You may be able to hear this noise in extremely quiet environments.  
Audio output is intermittent when the CD receiver is subjected to vibration.  
• The CD receiver is not a portable device. Use it in a location that’s not subject to shock or vibration.  
Headphone output is intermittent or there’s no sound.  
• This may be due to dirty contacts. Clean the headphones plug. See your headphones’ instruction manual for cleaning  
information. Also, make sure that the headphones cable is not broken or damaged.  
59  
     
Audio performance  
• Audio performance will be at its best about 10 to 30 minutes after the CD receiver has been turned on and had time  
to warm up.  
• Using cable ties to bundle audio cables with speaker or power cables may degrade the sound quality, so don’t do it.  
CD Playback  
Playback jumps.  
• The CD receiver is being subjected to vibration or the disc is scratched or dirty (see page 16).  
Can’t add tracks to the playlist for memory playback.  
• Make sure there’s a disc in the CD receiver. Also, you can only add valid track numbers. For example, if the CD  
contains 11 tracks, you cannot add track #12.  
The disc will not play.  
• Make sure the disc has been loaded correctly, with the label-side facing up.  
• Check to see if the surface of the disc is dirty (see page 16).  
• If condensation is suspected, turn on the CD receiver and leave it for 1 hour before playing any discs.  
• Some CD-R/RW discs may not be playable (see page 15).  
It takes a long time for playback to start.  
• It may take the CD receiver a while to read CDs that contain many tracks or files.  
Can’t play MP3 discs  
• Use only ISO 9660 Level 1 or Level 2 format discs (see page 15).  
• The disc has not been finalized. Finalize the disc.  
• MP3 files without a “.mp3” or “.MP3” filename extension are not recognized.  
Tuner  
Reception is noisy, stereo FM reception suffers from hiss, the Auto Preset function doesn’t preset all  
stations, or the ST indicator doesn’t light up when tuned to a stereo FM station.  
• Check the antenna connections (see page 17).  
• Change the position of the antenna (see page 41).  
• Move the CD receiver away from a nearby TV or computer.  
• Cars or airplanes can cause noisy interference.  
• The radio signal will be weakened if it has to pass through a concrete wall before reaching the antenna.  
• Try setting FM mode to mono (see page 41).  
• Move power cords and speaker cables as far away as possible from the tuner’s antenna.  
• When listening to an AM station, noise may be heard when you operate the remote controller.  
• If none of the above improves the reception, install an outdoor antenna (see page 18).  
If a power outage occurs or the power cable is disconnected:  
• If the preset stations are lost, preset them again (see pages 46, 47).  
• The clock and timer settings will be lost. Set the clock and timers again (see pages 52, 53).  
Can’t adjust the frequency of the radio.  
• Use the Rewind and Fast Forward [5]/[4] buttons to change the frequency of the radio (see page 41).  
RDS doesn’t work.  
• The FM station you are tuned to doesn’t support RDS.  
• Install an outdoor FM antenna (see page 18).  
• Change the position or direction of your outdoor FM antenna (see pages 18, 41).  
• Move the FM antenna as far away as possible from fluorescent lights (see page 41).  
Remote Controller  
The remote controller doesn’t work properly.  
• Make sure the batteries have been installed with the correct polarity (+/–) (see page 6).  
• Replace both batteries with new ones. (Do not mix different types of batteries or new and old batteries.)  
• The remote controller is too far away from the CD receiver, or there’s an obstacle between them (see page 6).  
• The CD receiver’s remote control sensor is being subjected to bright light (inverter-type fluorescent light or sunlight).  
• The CD receiver is located behind the glass doors of a audio rack or cabinet.

Troubleshooting—Continued  
USB Mass Storage Device Playback (CR-525UKD only)  
Can’t access the music files on a USB mass storage device.  
• Make sure that the USB indicator light is on. If the light is not on, make sure that it is connected correctly and that  
the USB mass storage device is one that is supported (see pages 37, 38).  
• The CD receiver supports USB mass storage devices that support the USB Mass Storage Class. However, playback  
may not be possible with some USB mass storage devices even if they conform to the USB Mass Storage Class.  
• Check that the memory format is FAT16 or FAT32.  
• USB mass storage devices with an internal USB hub are not supported.  
Can’t play MP3 files.  
• MP3 files without a “.mp3” or “.MP3” filename extension are not recognized.  
Can’t play WMA files.  
• WMA files without a “.wma” or “.WMA” filename extension are not recognized.  
• The WMA file’s copyright option is on. Don’t use the copyright option.  
External Components  
Interactive control with other Onkyo u-capable components is not working.  
• Make sure the u cables and analog audio cables are connected correctly (see pages 21 to 23). Connecting only an  
u cable won’t work.  
• Make sure the Input Display matches the type of device that you’ve connected to the CD receiver (see page 27).  
No sound is heard from a connected component.  
• Make sure the correct input source is selected (see page 25).  
• Make sure the analog audio cable is connected correctly (see pages 21 to 23).  
• Make sure that all audio connecting plugs are pushed in all the way (see page 20).  
No sound is heard from your turntable.  
• Make sure the turntable has a built-in phono equalizer.  
• If the turntable doesn’t have a phono equalizer built-in, you must provide one.  
Timers  
Timer playback or recording doesn’t work.  
• Make sure the clock has been set correctly (see pages 52, 53).  
• Timed operation will fail if the CD receiver is on at the specified On time, so make sure it’s set to Standby (see  
• The timer may overlap with another timer. If you program several timers, make sure they don’t overlap (see page 54).  
• If you press the [SLEEP] or [TIMER] button while a timed operation is in progress, the timer will be cancelled.  
• Make sure the u cables and analog audio cables are connected correctly (see pages 21 to 23).  
• If you’re using an Onkyo component for timed playback or recording, you must set the Input Display to match that  
component (see page 27).  
Clock  
The time is not displayed in Standby mode.  
• Set the CD receiver so that the time is displayed in Standby mode (see page 53).  
Onkyo is not responsible for damages (such as CD rental fees) due to unsuccessful recordings caused by the unit’s  
malfunction. Before you record important data, make sure that the material will be recorded correctly.  
The CD receiver contains a microcomputer for signal processing and control functions. In very rare situations, severe  
interference, noise from an external source, or static electricity may cause it to lockup. In the unlikely event that this  
should happen, unplug the power cord, wait at least 5 seconds, and then plug it again.
