• Make sure the main power switch is in the

“OFF” position. The battery pack does not
charge when it is connected to the DVD player
while DVD player power is turned on.

• A warm battery takes longer than normal to

charge. Wait until the battery cools to normal
temperature before trying to charge it.

• Replace the battery pack with a charged one or

switch to AC adapter power.

• Charging of a battery pack may become

disabled (and the charge lamp may fail to light)
whenever heat from the DVD player causes the
internal temperature of an attached battery pack
to rise above certain level. When this happens,
remove the battery pack from the DVD player.
Charging will start automatically when battery
pack internal temperature drops to a safe level.

• Make sure the temperature of the battery pack

is within the allowable temperature range of
10

°

C to 30

°

C for charging.

• Check to make sure that the AC adapter DC

cable is connected correctly.

• Try disconnecting the AC adapter DC cable from

the battery pack and then reconnecting it. If the
battery pack is attached to the DVD player, first
disconnect the battery pack DC cable from the
DVD player before performing the above step.

• Try charging another battery pack. The same

symptom occurring with another battery pack
may indicate a problem with the AC adapter. If
the other battery pack charges normally, it can
indicate a problem with the first battery pack or
that the first battery pack has reached the end
of its normal service life.

• Make sure the connected audio equipment is

turned on.

• Check if linear PCM is selected as the audio mode.

• When the space between tracks of some disks is

very short, two tracks can be recorded as a single
track, which causes a mismatch of track numbers.

• CD and MD track numbers may not match when

recording from a CD using programmed play or
direct skip.
