Page 13 highlights

The GPS III+ operates on 4 AA batteries (not included), which are installed at the base of the unit. These batteries provide up to 36 hours of continuous use (See page 87). Rechargeable NiCad or lithium batteries may also be used. H NOTE: The on-screen battery level indicator is calibrated for alkaline batteries, and will not be accurate when using NiCad or lithium batteries (see page 77). To install the batteries: 1. Flip up the metal ring at the base of the unit, and turn the ring 90° counterclockwise. 2. Install the batteries and close the battery compartment door. When replacing the GPS III+'s batteries, observe the polarity markings engraved in the plastic case. 3. Lock the door in the closed position by rotating the metal ring 90° clockwise. Battery life varies due to a variety of factors, including temperature, use of an external antenna, and backlighting. You may find that the battery life varies in different conditions and that lithium batteries provide longer life in colder conditions. An internal 10-year lithium battery will retain your data while you're changing batteries. GETTING STARTED Battery Installation Polarity Markings 3

The GPS III+ operates on 4 AA batteries (not included), which are installed at the
base of the unit. These batteries provide up to 36 hours of continuous use (See page
87). Rechargeable NiCad or lithium batteries may also be used.
NOTE
: The on-screen battery level indicator is calibrated for alkaline batteries,
and will not be accurate when using NiCad or lithium batteries (see page 77).
To install the batteries:
1.
Flip up the metal ring at the base of the unit, and turn the ring 90° counterclockwise.
2.
Install the batteries and close the battery compartment door. When replacing the GPS
III+’s batteries, observe the polarity markings engraved in the plastic case.
3.
Lock the door in the closed position by rotating the metal ring 90° clockwise.
Battery life varies due to a variety of factors, including temperature, use of
an external antenna, and backlighting. You may find that the battery life varies
in different conditions and that lithium batteries provide longer life in colder
conditions. An internal 10-year lithium battery will retain your data while you’re
changing batteries.
