Battery Installation; Battery Life - Home Theater Master MX-500 User Manual

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 27. Please replace the worn batteries with a fresh set as
soon as possible.
