Charging/Fast Charging

FAST CHARGING LED (yellow) - When lit, indicates
about 1-2 hours dependent upon initial voltage level at the start of the fast charge.When the charge light is on, the unit's internal
batteries are fast charging (charging in 1-2 hours). This can only be accomplished by using the supplied 18 VDC transformer.
Once the Fox's internal batteries are fully charged, the charge light will go off.
LOW BATT LED (red) - When lit, indicates battery is low and the
on will not be accurate (RSSI error > 1 dB). DO NOT COLLECT data while LOW BATT LED is on. When using
power with supplied cigarette lighter cable for unlimited run time. In addition, there are two charging methods. The first is
trickle charge, and the second is fast charge. The low battery light will come on when the FOX's internal batteries need charg-
ing. As soon as the LOW BATT light comes on, you should stop making measurements and plug the Fox into the appropriate
charging jack.
Trickle Charge: Charges the FOX's internal batteries overnight (approx. 8 hours).If the FAST CHARGING light is off and the
plugged into either the vehicle (via the 12 Volt supplied cigarette lighter adapter) or into the AC outlet (via the supplied switching
DC transformer) the FOX's internal batteries will trickle charge (charge overnight).
This input will both charge the internal NiCad battery and run the unit regardless of the initial state of the internal battery. The
rate of charging is about 10 times faster with the unit off.
Ignition noise must be filtered out externally. Some filtering is provided by the unit, but not as much as needed for a very noisy
vehicle due to space considerations.

GPS Power Switch

Use this switch to turn on or off the internal GPS sensor. Running the unit with this switch in the OFF position doubles battery
run-time. It is recommended that if LAT/ LON positions are not required, the GPS switch should be left in the OFF position.
