LOADING BATTERIES

The life of the batteries used with the remote control
is about 4 months with normal use. Also be sure to
replace batteries earlier when you notice that they
are getting weak.
1.
Remove the back cover.
2.
Insert the new batteries (AAA type) with
correct (+) and (–) polarity.
3.
Close the cover until it clicks.
Note:
Do not use old batteries and new batteries
together. This can result in corrosion or
leakage of battery fluid.
The supplied manganese batteries are for
checking operation. Usage of alkaline batteries
is recommended.
When discarding batteries, be sure to follow
the local regulations for your area. Do not put
batteries in a fire.

BATTERY REPLACEMENT INTERVAL

Under normal usage, alkaline batteries last
approximately four months. When the batteries
wear out, a battery mark is displayed on the LCD.
Although the remote control can still be used when
the battery mark is displayed, the batteries should
be replaced as soon as possible. The LCD
eventually starts to flash when buttons are
pressed, the remote control will be unable to
transmit signals or learn codes.
• This remote control uses non-volatile memory so
that the learned codes and macro programs are
retained even if the batteries are removed.
Reset the clock after replacing the batteries.
