Using the Backlight
If it is difficult to see the display or buttons when viewing the remote, the ML-500
backlight can be used to light up the display and buttons.
Turn on the backlight by pressing the LIGHT button on the right side of the remote
control. The backlighting will stay on, and then automatically turn off after
approximately 15 seconds. If you wish to turn off the backlighting without waiting,
press the LIGHT button again.
NOTE: Battery life is reduced with frequent use of the backlight feature.
Installing/Changing the Batteries
If the batteries are running low, the bottom of the LCD display will flash “LOW
BATTERY” whenever the ON button is pressed. Low batteries may shorten the
operating range of the ML-500. To change the batteries, perform the following:
1. While viewing the back of the ML-500, press the latch on the battery cover
(shown in the following illustration) and remove it.
