Battery Installation

Two AAA 1.5v alkaline batteries (included) are required for
operation of the remote control.
To install or replace batteries:
1. Slide the back cover off the control to open the battery
compartment.
2. Insert batteries. Follow the polarity markings inside the
battery compartment.
3. Replace the battery compartment cover.
NOTE:
1. When replacing batteries, do not use old batteries or a
different type battery. This may cause the remote control to
malfunction. If the remote is not going to be used for
several weeks, remove the batteries. Otherwise battery
leakage may damage the remote control.
2. The average battery life under normal use is about 6
months.
3. Replace the batteries when there is no audible beep from
the indoor unit or if the Transmission Indicator fails to light.
4. When batteries are removed, the remote control erases all
programmed settings. The control must be reprogrammed
after insertion of new batteries.
