Universal Remote Control (URS) MX-500 - Manual (Page 6)

2. Batteries
A. Battery Installation
Before the remote control can be used, the batteries need to
be installed. First, remove 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 devices will appear on the
LCD screen.
B. Battery Life
Under normal operating conditions, the batteries will last
approximately six months. If the batteries are running low,
you will notice reduced range from the remote, commands
that are not sent properly, or are not sent at all. You may
also notice the backlighting of the LCD screen and the
buttons is diminished. Should any of these occur, replace
the batteries immediately. To ensure proper performance of
the unit, use 4 new AAA alkaline batteries.
The remote control will retain the commands and settings
in memory even after the batteries are low or become
discharged. See Memory Lock on page 46. However, you
should replace the worn batteries with a fresh set as soon as
possible. Do not mix new and used batteries.
