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 of battery. This may cause the remote control
to malfunction.
2. If the remote is not going to be used for several weeks,
remove the batteries. Otherwise battery leakage may
damage the remote control.
3. The average battery life under normal use is about 6
months.
4. Replace the batteries when there is no audible beep from the
indoor unit or if the Transmission Indicator fails to light.
5. When the batteries are removed, the remote control erases
all programmed settings. The control must be
reprogrammed after insertion of the new batteries.
