Prolonging battery life
Note the following considerations for the battery in your handheld:
■ Under normal conditions your handheld battery should remain charged when
you place it in the cradle/cable for just a few minutes each day. You can
conserve battery life by doing any of the following:
– Reduce the brightness of the screen display. See “Adjusting screen
brightness” in Chapter 2 for more information.
– Change the Auto-off setting that automatically turns the handheld off after a
period of inactivity. See “Auto-off after” in Chapter 22 for more information.
– Turn off the Bluetooth™ feature when you’re not using it. See “Bluetooth
Preferences” in Chapter 22 for more information.
– Minimize accessing the expansion card slot.
– Moderate how often you access multimedia files, such as MP3 files
(expansion card required, sold separately) and video files.
■ If the battery becomes low in the course of normal use, an alert appears on the
handheld screen, describing the low battery condition. If this alert appears,
perform a HotSync
®
operation to back up your data; then leave your handheld
in the cradle/cable to recharge the unit. This helps prevent accidental data loss.
■ If the battery drains to the point where your handheld does not operate, it stores
your data safely for about a week. In this case there is enough residual energy
in the battery to store the data, but not enough to turn on your handheld. If your
handheld does not turn on when you press the power button, you should
recharge the unit immediately. The battery may not have enough residual
energy to power the indicator light, which is normally green when the battery
is charging.
■ If your battery drains and you have the unit in an uncharged state for an
extended period of time, you can lose all your stored data.
■ There are no serviceable parts inside your handheld, so do not attempt to open
the unit.
■ If you ever dispose of your handheld, please dispose of it without damaging the
environment. Take your handheld to your nearest environmental recycling
center.
Resetting your handheld
Under normal circumstances you will not have to use the reset button. On rare
occasions, however, your handheld may no longer respond to buttons or to the
screen. In this case you need to perform a reset to get your handheld running again.
