Battery Installation and
Start Up
Important Note
When replacing batteries, use only new or fully
charged batteries. Do not mix Alkaline and NiMH bat-
teries. Rechargeable batteries may typically display less
capacity than disposable batteries.
Remove the batteries from the unit if you don’t plan
to use it for several months. Storing batteries in the
unit for prolonged periods may result in leakage and
damage to the battery compartment.
Follow the manufacturer’s instructions for proper care
and disposal of used batteries. Do not incinerate used
batteries, as internal materials may ignite with explosive
violence.
Extensive use of backlighting and/or WAAS as well as
key beep tones will signifi cantly reduce battery life.
To set backlighting intensity and timeout, see page 48.
To disable WAAS, see page 47.
To mute the beep tones, see page 50.
Getting Started
Installing the Batteries
The GPSmap 76C operates on two “AA” batteries (not included),
which are located in the back of the unit. Alkaline or NiMH batteries
(see page 47 for setting the battery type) may be used. Stored data is
not lost when the batteries are removed.
T
o install batteries:
1. Remove the battery cover from the back of the unit. Turn the
D-Ring 1/4 turn counter-clockwise and then pull.
2. Insert the batteries, observing the proper polarity. A polarity
diagram can be found molded into the battery compartment.
3. Reinstall the battery cover by reinserting the locking pin in
the back of the unit. Turn the
D-Ring 1/4 turn clockwise to
lock in place.
