Trickle Charger/AC Adapter
The trickle charger/AC adapter supplied with the
GPSCOM 170 converts line voltage to the DC voltage
necessary to operate the unit. The AC adapter also slow-
ly recharges the Ni-Cad battery pack at a rate of 14 hours
for a full recharge. Make sure you charge the
Ni-Cad battery pack for 14 hours before using your
GPSCOM 170 to ensure optimum capacity and perfor-
mance. When charging the battery pack, be sure to turn
the unit off to ensure a full charge. The cigarette lighter
adapter will also trickle charge the battery pack only if the
unit is turned on and in the receive mode (GPS or com).
To recharge the Ni-Cad battery pack:
1. Attach the connector end of the adapter to the
GPSCOM 170 by sliding it into the slot on the left side of
the unit (observe the keyway on the unit connector and
the matching groove on the connector end).
2. Plug the other end into an electrical outlet.
Do not charge the GPSCOM 170 for more than 24
hours. Heat generated by overcharging can shorten
battery life and cause battery pack component failures.
Battery Pack Handling and Storage
The Ni-Cad battery supplied with the GPSCOM 170
has exposed terminals which may be shorted if not stored
properly. Don’t place a loose battery pack on or near
metal objects (paper clips, keys, tools, etc.) and be care-
ful when placing battery packs in handbags, toolboxes,
etc. Never immerse a battery pack in water. If the battery
pack becomes wet, wipe it dry before attaching it to
the unit.
Always store your GPSCOM 170 with the battery
pack installed. An internal lithium battery will save
almanac and waypoint data for an extended period of
time, but it is designed to allow you to recharge the bat-
tery pack, not replace it. If you’re storing the unit for the
season, make sure the batteries are fully charged.
