Battery considerations
Please note the following considerations when replacing the batteries
in your handheld:
■ Under normal conditions, your handheld batteries should provide
several months 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 9 for
more information.
■ If the batteries become 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 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). Never remove the batteries while
your handheld is turned on.
■ When replacing the batteries, always use good quality batteries of
the same type. Use only alkaline batteries with your handheld.
■ When you remove the batteries, the built-in backup power of your
handheld maintains memory data for a period of up to one
minute. Whenever you remove the batteries, replace them
immediately. If you encounter any difficulties in the course of
battery replacement, reinstall the original batteries and wait a few
minutes for the backup power to recharge.
■ If the batteries drain to the point where your handheld does not
operate, it stores your data safely for about a month. In this case,
there is enough residual energy in the batteries 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 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.
