Solution
Check connections to the AC adaptor or battery pack.
Release the hold mode.
Confirm the battery charge on the unit’s display.
You cannot turn on the unit with the remote control if the unit
is powered by the battery pack.
The unit turns off after it has been stopped for about
15 minutes (5 minutes when using the battery pack) to
conserve power. Turn the unit on again.

The charging time increases if the battery pack is warm and
charging may not be possible under some circumstances.
Wait for the battery pack to cool off.
Check connection to the AC adaptor.
The battery pack has protection circuitry that activates if the

work if this occurs. Use the unit at about 20 oC.

it to clear.
This unit cannot play discs other than those specified.
Wipe the disc clean.
Ensure the disc is inserted correctly.

the power source (AC or battery pack) reconnect the power
and turn the unit on again.
Check that the battery is inserted correctly.
