FEATURES
Your Optimus CD-5500 Compact Disc Player fea-
tures the latest in digital audio technology. Like
all compact disc (CD) players, the CD-5500 uses
a low-power laser beam to read digital information
from the CD then converts the information into
audio signals. Since only a light beam touches the
disc’s surface in the player, there is no disc wear
during normal use. With proper disc care, the origi-
nal sound quality can last indefinitely. Even when
the disc is slightly scratched, the CD-5500’s special
error-correction circuits can reconstruct missing
digital information.
The CD player includes these features:
Eight-Times Oversampling with Digital Filtering
— improves the CD’s sound by multiplying the
standard 44.1 kHz sampling rate by eight and using
a digital filter to reduce or eliminate the high-
frequency distortion caused by the digital-to-analog
conversion.
Digital Display — displays the CD player's operat-
ing status and other information, such as the total
number of tracks, the total playing time, the current
track, and the elapsed: time or remaining time.
Sequence Programming — lets you program up
to 20 tracks to play in any order you choose.
15-Track Number Grid — lets you quickly see the
total number of tracks (up to 15) you can play or
program from a CD.
Tri-Spot Laser Tracking — provides exceptionally
accurate tracking of the CD’s digital information.
3-inch CD Compatible — plays 3-inch CDs with-
out an adapter.
Floating Disc Tray — reduces interference caused
by external vibrations.
Automatic Search Music System (ASMS) — lets
you quickly find any track on a CD.
Audible Search — lets you rapidly play a CD in
either direction to listen for and locate a certain
section of a track.
Track Selector — lets you select a specific track
on a loaded CD.
Repeat Play — automatically repeats a programmed
sequence of tracks, all the tracks on a CD, a single
track, or a desired section of a track.
Random Play — continuously plays tracks it se-
lects at random.
STA-Compatible — lets you play and control the
CD changer through your Optimus STA-5500 or
STA-7500 Stereo Receiver/Ampilifier.
Remote Control — lets you contro! most of your
system’s functions from a distance. The remote
control requires 2 AA batteries, not supplied.
Compact Discs that you can play on your CD player
have this mark on them.

PREPARATION
CONNECTING THE CD PLAYER TO
A RECEIVER/AMPLIFIER
Select a location for your CD player that is near
your receiver/amplifier and a standard AC outlet.
Caution: Do not place the CD player on top of the
receiver/amplifier or any other component that
produces heat.
Note: If other audio components or their wires are
near the CD player, you might hear a hum during
play. You can usually eliminate the hum by moving
the components or their wiring.
1. Connect one end of the supplied audio cable to
the CD player’s L (left) and R (right) OUTPUT
jacks.
Receiver/Amplifier
2. Connect the other end of the cable to the re-
ceiver/amplifier’s corresponding left and right
CD, AUX, or TAPE input jacks.
Caution: Do not use the receiver/amplifier’s
PHONO input jacks. Doing so could damage the
receiver/ampilifier.
3. Plug the CD player’s power cord into a standard
AC outlet.
CONNECTING THE DIGI-LINK
CABLE
If you connect your CD player to an STA-5500 or
STA-7500 stereo receiver/amplifier, you can also
control the CD-5500 with the receiver/amplifier’s
remote control by connecting the supplied DIGI-
LINK cable.
STA-5500/STA-7500
CD-5500
1. Connect one end of the DIGI-LINK cable to the
CD player’s upper DIGI-LINK jack.
2. Connect the other end of cable to the STA-5500
or STA-7500 receiver/amplifier’s DIGI-LINK jack.

USING HEADPHONES
To listen through headphones, connect a pair of
low-impedance stereo headphones with a },-inch
plug to the PHONES jack. Adjust LEVEL to set the
volume to a comfortable listening level.
Listening Safely
Do not listen at extremely high volume levels.
Extended, high-volume listening can lead to per-
manent hearing loss. Follow these guidelines to
protect your hearing, especially when you use
headphones.
e Always start by setting the volume to the lowest
level possible before you begin listening. Put
the headphones on, then gradually increase the
volume.
e Once you set the volume, do not increase it. Over
a period of time, your ears adapt to the volume
level, so a volume level that does not cause dis-
comfort might still damage your hearing.
INSTALLING THE REMOTE
CONTROLS BATTERIES
Your CD player’s remote control requires two AA
batteries. For longest life, we recommend alkaline
batteries, such as Radio Shack Cat. No. 23-552.
1. Remove the battery compartment cover by
pressing down on the cover and sliding it in the
direction of the arrow.
2. Insert two fresh AA batteries as indicated by the
polarity symbols (+ and —) marked inside the
compartment.
Notes:
e Use only batteries of the required size and
type. Incorrect batteries could damage the
remote control.
e Never leave dead or weak batteries in the
remote control. They can leak damaging
chemicals.
3. Replace the battery compartment cover.

BASIC OPERATION
CD-5500 PRECAUTIONS ° If you move the player from a very cold room to
a warmer one, moisture might condense on the
pickup lens, preventing proper CD play. If this
happens, wait 30 minutes before resuming play.
e This CD player has a wide dynamic range. Do
not turn up your receiver/amplifier’s volume too
high during soft (low volume) parts of the music
or you might damage your hearing when a sud- e Keep the CD tray clean.
den loud passage occurs.
¢ Do not place more than one CD or foreign ob-
jects in the CD tray. This can damage the drive
mechanism.
e Although this CD player has a floating disc tray to
reduce interferences caused by minor external
vibrations during playback, a sudden shock or
jolt could still make the speed of the CD’s rotation
change suddenly and produce noise. This is not
a malfunction.

SPECIAL FEATURES
SELECT PLAY
After you load a CD, you can select a track by
directly entering the desired track’s number, by
using the automatic search music system to quickly
skip forward or backward to the beginning of tracks,
or by using Intro Scan to automatically scan the
tracks so you can listen to the first 10 seconds of
each track until you hear the selection you desire.
Directly Selecting a Track
To directly select a track, enter the desired track
number using the number buttons. About 4 to 5
seconds after you enter the track number, the CD
player starts playing the selected track.
Note: To select a two-digit track number, you must
press the second digit within 2 seconds after you
press the first digit.
Automatic Search Music System
(ASMS)
ASMS lets you quickly locate the beginning of any
track during play, including the track that is cur-
rently playing.
Press ASMS/SEARCH PPI on the player or ASMS
PPI on the remote control to skip forward through
the tracks.
Press ASMS/SEARCH K@4f on the player or ASMS
K€ on the remote control to skip backward through
the tracks.
Note: If you press ASMS/SEARCH Pf on the
player or ASMS PPI on the remote control at the
final track, the display returns to the first track. If you
press ASMS/SEARCH K@f on the player or ASMS
K4¢<4 on the remote control at the first track, the
display returns to the final track.

quickly locate a specific section of that track.
During play, press and hold ASMS/SEARCH PPI on
the player or SEARCH PP on the remote control to
search forward or ASMS/SEARCH K@4 on the player
or SEARCH <4 on the remote control to search
