4.3.2.3 Backlight (2-3)
There are three options available for backlight operations, ON, OFF, and SMART. The ON option turns
the backlight on and it remains on until it is turned off using the OFF option. The backlight should only be
needed indoors and at night. Operating the VR100 with the backlight on will greatly reduce the operating
time between battery charges. The SMART option leaves the backlight off if the keypad is inactive but
will turn the backlight on for five seconds when a button is pressed on the keypad.
To change the backlight setting, from the Main screen:
1.
Select Config (right selection button).
2.
Press “2” on the keypad.
3.
Press “3” on the keypad. The current backlight setting is displayed with an arrow symbol.
4.
Press the up or down arrow button until the desired option is shown on the display.
5.
Press the button attached to “Accept” to accept the change, or “Cancel” to exit the menu without
changing the backlight setting.
