5 -- Icon Warnings
This section describes icons displayed only under warning conditions.
5.1 Low Battery Icon ( )
The low battery icon is displayed when you have approximately 5% of battery life
remaining. Immediately after the Low Battery icon is displayed, you have approximately
1 - 1.5 hours with backlight on, or approximately 20-25 hours with backlight off before
the NOMAD will not power ON.
IMPORTANT! When replacing the battery all stored information will be lost. Remember
to recalibrate the compass when replacing the battery.
5.2 Disturbance Icon (DIST )
The disturbance icon is displayed when an external disturbance is sensed by the
NOMAD. If the icon is displayed, check yourself for metal objects (belt buckles, rings...),
or check for nearby objects that could cause the disturbance. Remove NOMAD from
the disturbance.
If the disturbance is caused by something the NOMAD cannot be removed from (con-
centration of Iron Ore in the ground), recalibrate the NOMAD to differentiate between
Magnetic North and the disturbance. You must use the compass in the same position
that it was calibrated, however. If you move from that position, NOMAD may have to
be recalibrated. See section 2.1-1 for Calibration.
