2-14 Initial Setup
Using the Backlight
To provide more visibility for the display, the TransPort can be
equipped with a backlight. If your unit has a backlight, you can
operate it as described below.
To turn on the backlight:
Press and hold down the [ON] key, then press the [7] key. To
brighten the back light, press the [7] key repeatedly.
To turn the backlight off:
Press and hold down the [ON] key, then press the [4] key.
Note: If the backlight is set to its brightest setting, you may have
to press the [4] key more than one time to turn the back
light off.
Setting Backlight Timeout
Using the Backlight Timeout function, you can set a specified
time that the backlight will remain on before turning itself off.
The final prompt in the Display Menu, BACKL, enables users to
conserve battery power by adjusting the period of time the
backlight remains on before automatically shutting off.
After pressing [DISP], press the [←] [→] keys until BACKL
appears, then press [F2]. A prompt asks for a number of minutes
(over a range from 0 to 60). Use the numeric keys to select a
value, and press [ENT].
