• The service life of an alkaline battery is about 1 year.
However, a battery whose time limit is approaching
may be exhausted soon. The recommended usable
time limit is indicated (month/year) on the bottom of
the battery.
• To prevent liquid leakage, take out all batteries when
the remote controller is not going to be used for a
long time.
CAUTION:
If liquid from the batteries gets onto your skin or
clothes, wash it well with clean water.
If liquid from the batteries gets into your eyes, wash
them well with clean water and consult a doctor at
once.
• Do not use rechargeable batteries.
• Replace the 2 batteries with new ones of the same
type.
• Dispose of exhausted batteries in the correct manner.
When the remote controller cannot be
used (emergency operation)
When the batteries of the remote controller run out or
the remote controller malfunctions, the emergency operation can be done using the EMERGENCY OPERATION
switch.
