CDP-CSF/CSS/C57

FEATURES

Compact disc player with 5 disc trays
Plays up to 5 discs continuously with its disc compartment
having 5 disc trays (MULTI play).

Direct access to the deslred disc
Any disc in the compartment can be played with the DISC
SELECT button any time you want (MULTI PLAY).

Various lunctlons

c PROGRAM play function for playing up to 32 selections on
any disc in a desired order

ISHUFFLE play function for playing the selections in a
random order

0 Repeat function for normal, PROGRAM and SHUFFLE play
in either SINGLE or MULTI mode

Memory back up

The programmed playback order is retained for
approximately 3 days with the power turned off or with the
disc compartment being opened. This allows you to confirm
the programmed order referring to the disc labels with the
compartment open.

CAUTIONS ABOUT DISCTAB LE

*Do not push the disc-table in or pull it out
forcibly, since the disc-table does not work
without the power switched on.

*Be careful not to disturb the disc-table in
ejecting motion.

If something like a wire or a finger is caught
by the disc-table, depress the OPEN/CLOSE

button as soon as possible, so that the disc-
table will move reversely.

SAFETY CHECK-OUT (US Model)

After correcting the original service problem,
perform the following safety check before releasing
the set to the customer:

Check the antenna terminals,metal trim, metallized
knobs, screws, and all other exposed metal parts for
AC leakage. Check leakage as described below.

LEAKAGE TEST

The AC leakage from any exposed metal part to
earth ground and from all exposed metal parts to any
exposed metal part having a return to chassis, must
not exceed 0.5 mA (500 microampers). Leakage
current can be measured by any one of three
methods.

1. A commercial leakage tester, such as the
Simpson 229 or RCA WT-540A. Follow the
manufacturers instructions to use these instru-
ments.

2. A batterycperated AC milliammeter, The Data
Precision 245 digital multimeter is suitable for
this job.

3. Measuring the voltage drop across a resistor by
means of a VOM or battery-operated AC volt-
meter. The limit indication is 0.75 V, so
analog meters must have an.aecurate low-
voltage scale. The Simpson 250 and Sanwa
SH-63Trd are examples of a passive VOM that
is suitable. Nearly all battery operated digital
multimeters that have a 2 V AC range are
suitable. (See Fig. A)
