Additional tips for maximizing battery life

Reduce the brightness of the display. (Display dims automatically when batteries are
low.)

Reduce the volume. (Volume decreases automatically when batteries are low.)

Set navigation to beep output in "Settings > Navigation Settings > Set guidance
preference."

Set to "screen off" while in use. (See page 5.)

Keep the device out of the cold. Batteries are very sensitive to temperature. In cold
conditions, the run time of the batteries is greatly curtailed. Optimum results are
achieved at around 70°F.

When using rechargeable batteries, follow the manufacturer‘s instructions for
maximum run time.
