Operations - Garmin GPS 50 Owner's Manual

We encourage you to read through this manual and experiment using the
built-in simulator. This will help you quickly master the power of the GPS 50.

1.2 OPERATIONS

You may use your GPS 50 for both portable and fixed operations. The unit
may be operated from external AC power using a battery charger, external
5-40 volt DC power using the power/data cable or cigarette lighter adapter,
or using a battery pack.
Handheld Operation:
For handheld operation, the GPS 50 is powered by a AA battery pack which
should be filled with four high quality alkaline batteries commonly found at
retail stores. A rechargeable nicad battery pack is also available for handheld
operation.
In order to track GPS satellites, the unit must be situated with the antenna
pointed straight up and should not be blocked by objects or people (signal
reception through thin fabric such as canvas may be adequate but degraded).
A lanyard is provided to prevent accidental dropping of your GPS 50.
(Connect the lanyard to the eyelet on the back of the unit.)
Fixed Mount Operation:
A universal mount is supplied for swivel or surface mount installation in a
boat. The unit may be operated using vehicle power through the power/data
cable or it may be operated using the battery pack. While using vehicle
power, you may wish to leave the battery pack in the unit. In the event of
vehicle power failure, the GPS 50 will automatically switch to battery power.
In addition to supplying power to the unit, the power/data cable allows you to
interface your GPS 50 with other marine electronic devices such as plotters
or autopilots.
A Marine/RV Remote Antenna is available for installations which require an
external antenna for an unobstructed view of the sky. This weather-proof
antenna includes 30 feet of low-loss antenna cable. The remote antenna has
been constructed to thread onto a standard 1" antenna mount. Antenna
mounts, commonly used to attach VHF radio antennas and Loran-C couplers,
are readily available from your local marine accessories dealer.
A Magnetic Mount Antenna is also available for attaching a remote antenna
to a metallic surface. This weather-proof antenna includes 10 feet of low-loss
antenna cable. A cigarette lighter adapter cable may be used to power the
unit in vehicle applications.
