Preparation  
Caution: Do not connect the CD changer to AC power until you complete all  
other connections.  
Connecting the CD Changer  
to Your Receiver or Amplifier  
1. Select a location for your CD changer that is near your receiver or ampli-  
fier and a standard AC outlet.  
Note: If you place the CD changer too  
near other audio components or their  
wires, you might hear a hum when you  
play a CD. Move the components or  
their wires to eliminate the hum.  
Caution: Do not place the CD changer on top of the receiver or amplifier  
or on any other component that gets hot.  
2. Plug one end of the supplied audio cable into the CD changer’s L (left)  
and R (right) LINE OUT jacks, matching the red plug to the red R LINE OUT  
jack and the white plug to the white L LINE OUT jack.

3. Plug the other end of the audio cable into the receiver’s or amplifier’s left  
and right CD, AUX, or TAPE input jacks.  
Caution: Do not connect the CD changer to the receiver’s or amplifier’s  
PHONO inputs.  
You can connect the CD changer to another digital audio product such as a dig-  
ital recorder. You need an optical cable (Cat. No. 42-2466, available by special  
order through your local RadioShack store) for this connection. To make the  
connection, remove the protective dust cap from the digital jacks, and connect  
the optical cable to the jacks.  
Connecting to Another  
Digital Audio Product  
Note: Be sure to leave the dust cap in  
place when you are not using the jack.  
After you have connected the CD changer to your receiver or amplifier, plug the  
CD changer’s power cord into a standard AC outlet.  
Connecting Power  
Caution: To prevent electric shock, the plug’s blades are polarized and fit only  
one way. If the plug does not fit easily, turn it over and try again. Do not force the  
plug into any AC outlet.  
Note: Do not connect the CD  
changer’s power cord to an amplifier  
or other switched outlet. The CD  
changer loses memorized settings  
when power is removed.  
The Synchro-Record feature lets you easily copy CDs to cassette tapes. If you  
have a cassette deck that has a CD-DECK SYNCHRO jack (such as many Opti-  
mus Professional Series cassette decks), the CD changer can automatically  
start and stop with the cassette deck. Connect the CD-deck synchro-cord, sup-  
plied with the cassette deck, to the CD changer’s and cassette deck’s CD-DECK  
SYNCHRO jacks.  
Connecting to a Cassette  
Deck’s Synchro Jack  
For details on connection and operation, refer to the cassette deck’s owner’s  
manual.

Preparation  
Your CD changer’s remote control requires two AA batteries (not supplied) for  
power. We recommend alkaline batteries (RadioShack Cat. No. 23-552).  
Installing the Remote  
Control’s Batteries  
1. Press in the battery compartment cover’s latch and lift off the cover.  
2. Put two fresh AA batteries into the compartment as indicated by the polar-  
ity symbols (+ and –) marked inside.  
3. Replace the cover.  
Cautions:  
• Use only fresh batteries of the required size and recommended type.  
• Do not mix old and new batteries, different types of batteries (standard,  
alkaline, or rechargeable), or rechargeable batteries of different capaci-  
ties.  
• Always remove old or weak batteries. Batteries can leak chemicals that  
can damage electronic circuits.  
• If you do not plan to use the remote control for a month or more, remove  
and store the batteries.  
Note: If the remote’s range is reduced, replace the batteries immediately.  
If your receiver/amplifier (such as most Optimus Professional Series receiver/  
amplifiers) has an OSR mark, the receiver/amplifier’s remote can control some  
of the CD changer’s functions.  
Using a Receiver’s Remote  
Control with the CD Changer  
CONTROL IN  
CONTROL OUT  
Plug one end of the supplied control cable into the CD changer’s  
jack. Plug the other end of the cable into the receiver/amplifier’s  
jack.  
Notes:  
• This connection disables the CD changer’s infrared sensor. Aim the  
remote control at the receiver/amplifier’s infrared sensor.  
• You must also connect audio cables to your receiver for the receiver’s  
remote control to operate your CD changer.  
For details on connection and operation, refer to the receiver/amplifier’s owner’s  
manual.

Basic Operation  
Warning: To protect your hearing, set the volume on your receiver or amplifier  
to its lowest level before you load and play a CD.  
Caution: Do not set the volume on your receiver or amplifier too high while  
playing soft or quiet portions of a music program. Due to the CD changer’s wide  
dynamic range, the speakers might be damaged if the music program includes  
a sudden loud passage.  
Many of the CD changer’s buttons also have a corresponding button on the  
remote control, and you can use either the CD changer or the remote control to  
control the function.  
Using the Remote Control  
To use the remote control, point it at the infrared sensor on the left side of the  
front panel and press the control button.  
Note: The remote operates the CD  
changer from up to 23 feet away and  
within 30° of the front of the CD  
changer.  
When the remote control’s operating distance reduces or if the remote control  
stops working, replace the batteries.  
The multi-disc rack holds 100 CDs. The disc slots are numbered in clockwise  
order, from 1 to 100, and can hold either 3-inch or 5-inch CDs.  
Loading CDs in the Rack  
Follow these steps to load up to 100 CDs in the slots.  
1. Press POWER to turn on the CD changer. If necessary, repeatedly press  
DISC NUMBER (or DISC on the remote) so the slot number you  
want appears on the display.  
Note: Always handle CDs by their  
edges. Fingerprints and scratches on  
a CD’s surface can prevent the laser  
beam from correctly reading the digital  
information. For more information, see  
“CD Care Tips” on Page 18.

If a slot does not contain a CD, the CD changer displays no diSC next to  
the disc number as it skips to the next slot.  
The CD changer memorizes which slots contain CDs, then it skips empty  
slots on subsequent play passes. Opening the rack cover (to load/unload  
CDs, for example) resets this memory.

Care and Maintenance  
Your Optimus CD-8400 101-Disc Compact Disc Changer is an example of  
superior design and craftsmanship. The following suggestions will help you care  
for the CD changer so you can enjoy it for years.  
Keep the CD changer dry. If it gets wet, wipe it dry immediately. Liquids can con-  
tain minerals that can corrode electronic circuits.  
Handle the CD changer gently and carefully. Dropping it can damage the circuit  
boards and case and can cause it to work improperly.  
Use and store the CD changer only in normal temperature environments. Tem-  
perature extremes can shorten the life of electronic devices, damage batteries  
in the remote control, and distort or melt plastic parts.  
Keep the CD changer away from dust and dirt, which can cause premature  
wear of parts.  
Wipe the CD changer with a damp cloth occasionally to keep it looking new. Do  
not use harsh chemicals, cleaning solvents, or strong detergents to clean the  
CD changer.  
Modifying or tampering with the CD changer’s internal parts can cause a mal-  
function and might invalidate your CD changer’s warranty. If your CD changer is  
not working as it should, take it to your local RadioShack store for assistance.  
Even though a CD is very durable, you should handle it with care.  
CD Care Tips  
• Keep the CD inside the CD changer or in its protective case or sleeve  
when you are not playing it.  
• Handle a CD by its edges to avoid fingerprints which can prevent the CD  
changer’s laser beam from accurately reading the CD. Your local  
RadioShack store sells a suitable CD cleaner kit.  
• Do not write on either side of the CD, particularly the non-label side. (Sig-  
nals are read from the non-label side.)  
• Keep the CD dry. A water drop can act as a lens and affect the laser  
beam’s focus.  
If a CD skips or the CD changer displays Υ1 when you try to play it, it might be  
scratched. Your local RadioShack store sells a Scratch ’n Fix kit (Cat. No. 42-  
127) that might help remove the scratch and stop the skip. See also “Trouble-  
shooting” on Page 16.
