A. Battery Installation
Before the remote control can be used, the supplied
batteries need to be installed. First, unsnap the battery
cover on the back of the unit and install the four AAA
batteries inside the battery compartment as shown. Make
sure the batteries line up with the (+) and (-) markings.
Improper installation could damage the remote control.
When you're done, slide the battery cover back on. The
remote control starts up automatically and the default
device components will appear on the LCD.
B. Battery Life
Under normal operating conditions, the batteries
supplied with the remote control will last approximately
six months. If the batteries are running low, you will
notice reduced range from the remote control,
commands that are not sent properly, or are not sent at
all. You may also notice the backlighting of the LCD
screen and the button is diminished.
Should any of these occur, replace the batteries
immediately. To ensure proper performance of the unit,
only use new alkaline batteries.
The remote control will retain the commands and
settings in its memory even after the batteries are low or
become discharged. See Memory Lock on page 34.
Please replace the worn batteries with a fresh set as soon
as possible.
