WARNING: Do not use a sharp

object to remove user-replaceable batteries. Contact your local wastedisposal department to properlyrecycle the batteries.

Optimizing Battery Life

Use premium batteries for optimal performance and maximum batterylife.

Consider the following suggestionsto maximize battery life:

Avoid excessive use ofthe backlight, which willsignicantly decrease battery life.

Select a shorter backlighttimeout. See page 24.

Turn off GPS when not using.
