CAUTION
Before replacing the battery, be sure to turn the power OFF. Failure to do so might
cause electric shock.
Do not touch internal components immediately after turning the power OFF to
replace the battery. Doing so might cause burns.
• Do not insert the battery with the polarities (+,-) reversed.
• Do not use damaged (broken battery skin, leaking battery fluid) batteries.
• Do not throw batteries into fires, or charge, short-circuit, disassemble or heat bat-
teries.
• Store batteries in low-temperature, dry locations.
Failure to observe the above cautions may cause batteries to emit heat or split, or
battery fluid to lead.
Store batteries out of the reach of small children.
Batteries are small and are easy to swallow. If a child swallows a battery, consult a
physician immediately.
When disposing of used batteries at the user site, observe bylaws.
If you touch components inside the DCP31, touch a grounded metal object to dis-
charge any static electricity from your body.
Otherwise, static electricity might damage the components.
Handling Precautions
• Batteries left in storage for a long time discharge electricity,
reducing their service life. Purchase new batteries as required.

BAT LED blinking
When low battery voltage is detected, the BAT LED on the console
blinks. The voltage level for detection of low battery voltage is set
higher than the required voltage level for holding stored setups in
memory.
Accordingly, as soon as the BAT LED starts blinking, stored setups
can still be held in memory. However, if the
DCP31
is turned back
ON after being left for a long time with its power OFF and the BAT
LED blinks, setups stored to memory may be damaged.
■
Replacing the battery
The parameter setups and program setups on the
DCP31
are stored
to battery backed up memory (RAM). So, stored setups are held in
memory even if the
DCP31
is turned OFF.
However, when battery voltage becomes low, stored setups are no
longer held in memory when the
DCP31
is turned OFF.
