About the AAA batteries
Please note the following considerations when replacing the batteries
in your handheld:
■ Under normal conditions, depending on your usage pattern, the
AAA batteries of your handheld should provide weeks of use. You
can conserve battery life by minimizing the use of the backlight
feature, and changing the Auto-off setting that automatically turns
the handheld off after a period of inactivity. See “General
preferences” in Chapter 8 for more information.
■ As the batteries become low in the course of normal use, messages
appear onscreen alerting you to the low battery condition. Replace
the batteries as soon as you can after the first alert appears.
Remember to perform a HotSync
®
operation to back up your data
before you replace the batteries. This helps prevent accidental data
loss.
■ When replacing the batteries, begin by turning your handheld off
(so there is no screen display).
■ When replacing the batteries, always use good quality batteries of
the same type. Do not mix old and new batteries. Use only alkaline
batteries with your handheld.
■ When you remove the old batteries, the built-in backup power of
your handheld maintains memory data. Whenever you remove
the batteries, replace them immediately. We recommend replacing
batteries within a period of one minute. If you encounter any
difficulties or delays while you’re replacing the batteries, reinstall
the original batteries and wait a few minutes for the backup power
to recharge.
■ If the batteries drain to the point where you cannot turn on your
handheld, there is enough residual power in the batteries to
preserve your data safely only for a few days beyond that point. If
your handheld does not turn on when you press the power button,
you should replace the batteries immediately.
■ If you leave drained batteries in your handheld for an extended
period of time, you can lose all of the stored data. If this happens,
replace the batteries and use the reset button to reset your
handheld. (See “Resetting your handheld” later in this chapter for
details.) After you reset your handheld, perform a HotSync
operation to restore the data from your computer.
