To remove the batteries, remove battery
“3” first.
Notes:
• The memory backup batteries will not be
consumed as long as the power is supplied
from an AC outlet, loaded 10 batteries, or
car battery (DC12V). However, if no power
is supplied to the system, the memory
backup batteries should be replaced with
new ones approximately every 12 months to
securely maintain the contents of the
memory.
• Before replacing the memory backup
batteries, always connect the AC power
cord to the system to prevent the contents of
memory from being erased.
• When a power failure occurs, the time
indication disappears from the display to
save the battery power of the memory
backup batteries.
CAUTION:
To avoid battery leakage or explosion:
• When you need to replace the batteries,
replace all batteries at the same time with
new ones. Before replacing, you need to
supply AC power to the system.
• Do not use an old battery with new ones.
• Do not use different types of batteries
together.

batteries (not supplied)
To remove the batteries, remove battery
“10” first.
Notes:
• When you operate the system on mains
(AC) power or on car battery (DC12V), the
power source automatically switches from
batteries to AC or DC12V. However, you
should remove the 10 batteries when
operating on AC power or car battery
(DC12V).
• When the batteries are exhausted, the
following symptoms will occur:
- Mistracking occurs during disc playback.
- Sounds are distorted intermittently during
tape playback.
- “DC OFF” flashes on the display, then the
power goes off.
If this happens, replace the batteries.
• It is recommended to use AC power cord
when recording important material or
listening to a disc.
CAUTION:
To avoid battery leakage or explosion:
• Remove the 10 batteries when the system is
not in use for an extended period of time.
• When you need to replace the batteries,
replace all batteries at the same time with
new ones.
• Do not use different types of batteries
together.
• If the power is supplied through the
batteries, the display will be blank with the
system turned off (at standby).
Unplug the AC power cord from the
system to supply the power through the
batteries; otherwise, the system does
not work.
