9. Backlight
Used in dark conditions to light the display,
improving visibility.
Select BACKLIGHT with the ARROW controls
and press ENTER. Use the ARROW controls to
select the desired BACKLIGHT level. The
BACKLIGHT level will be visible on the display.
The current level is shown on the right side of the
display. The graphic control knob shows the
relationship of the current setting to minimum and
maximum levels. Minimum is 0 (no light). The
maximum backlight setting will reduce battery life
by as much as 50% depending on the type of
batteries and how long it is used. Lower
BACKLIGHT settings will have significantly less
drain on battery life.
When the detector is first turned on, it is normal
for the backlight to be on during the opening
display and BATTERY CHECK. If the
BACKLIGHT is off, it will fade when the MAIN
MENU display appears. If the BACKLIGHT is
ON, it will continue until turned off manually or a
different program is selected. BACKLIGHT can
be saved as part of a custom program, for example
a NIGHT HUNT program.
When Backlight is ON and the TRIGGER is
squeezed and released to begin searching,
"BACKLIGHT ON" will appear continually on
the display to warn you of the extra battery duty.
EMERGENCY BACKLIGHT - If in the dark
you cannot see the display to turn the
BACKLIGHT on, holding the TRIGGER and
pressing MENU will bring up the BACKLIGHT
adjustment screen. Release the TRIGGER and
press ARROW up to select a level you can see the
display. Squeeze and release the TRIGGER to
continue.

Tip - Use only when
needed, and only as bright
as needed, for acceptable
display visibility. Backlight
use will decrease battery
life. The brighter the level,
the higher the battery
usage.
CAUTION
If the instrument is turned ON and the
EMERGENCY BACKLIGHT sequence is
used, the BACKLIGHT will stay ON only
while you stay in that program. Pressing
MENU and selecting another program will
turn BACKLIGHT OFF, if BACKLIGHT
is not also ON in that particular program.
If in the dark at the time the instrument is
turned ON, you may need to squeeze and
release the TRIGGER and then use the
EMERGENCY BACKLIGHT sequence.
You can then find the program you desire,
press ENTER, press ENTER for Air
Balance, and press ENTER for Ground
Balance. Use the EMERGENCY
BACKLIGHT ON sequence a second time
if the BACKLIGHT fades in that program.
Unlike past Spectrum
®
instruments, the
Spectrum

XLT
®
BACKLIGHT is no
different than any of the other
adjustments. It can be saved in the custom
programs or short term volatile memory.
However, factory preset programs use the
OFF (0) setting as a default (standard
setting).
