This player incorporates the latest digital anti shock circuit, which prevents
interruption of the sound output if the unit is subjected to shock or vibration
during disc playback. The anti shock system will automatically start when a
disc is played, is shown in the display during start up then is flashes
slowly when the data buffer is full and the JOGGABLE system is most
effective.
Notes:
1. While the FULL SHOCK function provides continuous sound output when the
unit is subjected to shock or vibration; it will not correct errors arising from the
use of defective scratched or dirty discs.

CHARGING AND USE OF RECHARGEABLE BATTERIES
Note
Rechargeable Battery Operation
You may play DISC'S whilst charging the batteries.
4. If the operating time decreases drastically even when the rechargeable
nickel-cadmium batteries are properly recharged, purchase a new set
of rechargeable nickel-cadmium batteries.
5. When charging for the first time or after a long time, playing time may
be reduced. In this case, charge and discharge the batteries several
times.
This unit can fully recharge the specified rechargeable battery, in
approximately 15 hours. The rechargeable batteries (NOT supplied)
should be recharged before they are used form the first time because
they are low in power or if they have not been used for a long period
(over 60 days)
1. Open the battery compartment cover and insert two of the recommended
rechargeable batteries, matching polarity. (1.2V 650mA)
BOTH
BATTERIES MUST BE OF RECHARGEABLE NICKEL-CADMIUM
TYPE, OTHERWISE THE BATTERIES MAY EXPLODE OR LEAK.
2. Plug in the AC adaptor and set the Recharge switch to ON position to
start charging.
3. After 15 hours. Please unplug the AC adaptor and switch the Recharge
switch to the OFF position.
DO NOT CHARGE CONTINUOUSLY FOR 24 HOURS OR MORE.
DOING SO CAN CAUSE THE PERFORMANCE OF THE
RECHARGEABLE BATTERIES TO DETERIORATE.
