NOTE
Using the display backlight reduces the battery life. The
display backlight operates only from the charged NiCad
batteries. If the NiCad batteries are not charged, or if
the control unit is disconnected from the gauge, the
gauge uses the alkaline batteries, and therefore the
backlight will not operate.
To set up the backlight option, press 〈5〉 LCD Backlight at the
Gauge Setup menu shown on page
3–9 (use the arrow keys to scroll
to the LCD Backlight menu). The gauge displays the four backlight
modes, as shown:
To use the backlight only when the 〈LIGHT〉 key is pressed, select
〈1〉. To use the backlight after a count, select 〈2〉. To use the
backlight after a keypress, select
〈3〉. To use the backlight after
either a count or a keypress, select
〈4〉. After the mode is selected,
the gauge displays:
Using the number keys, enter the time in seconds that the display is
to remain backlit. Press the
〈ENTER〉 key.
The gauge saves the backlight setup and returns to the Gauge Setup
menu. Return to the Ready screen by pressing the 〈ESC〉 key.
NOTE
The gauge also features a hardware adjustment for the
display contrast. If the gauge display is difficult to read
in bright light, adjust the contrast as described in the
Display Contrast section on page C–27.
