Battery Check
This option provides a graphic indication of
battery condition on a scale from “Low” to
“Full.” The combined voltage of the six AA
batteries is indicated at the bottom center of
the screen. Also, a small battery symbol is
shown at the top of the main menu indicating
the battery capacity.
For satisfactory
receiver operation,
battery voltage
should be between
6 and 9 volts.
You will receive a warning message on the
display if battery voltage falls below 6 volts.
After the warning message shows on the
display, the receiver will continue to operate
for 20 to 30 minutes. Switch the display
backlight off to conserve power. Replace the
batteries promptly to avoid loss of time, user
waypoints, routes, and system setup
information stored in memory.
Do not allow low or discharged batteries to
remain installed in the receiver as leakage
could damage internal components.
