Battery considerations
Pleasenote the following considerationswhen replacing the batteries
inyour handheld computer:
■Undernormal conditions, your batteries should provide several
monthsof use. You can conserve battery lifeby minimizing the use
of the backlight feature, and changing the Auto-off setting that
automatically turns the handheld computer off after a period of
inactivity. See“General preferences” in Chapter 7 for more
information.
■If thebatteries become low in the course of normal use, an alert
appearson th es creen describing the low battery condition. If this
alertappears, perform a HotSync®operation to back up your data
beforeyou replace the batteries. This helps prevent accidental data
loss.
■When replacing the batteries, begin by turning your handheld
computer off(so there is no screen display). Never remove the
batteries while your handheld computer is turned on.
■Whenrep lacing the batteries, always use g ood quality batteries of
thesametype.Useonlyalkalinebatterieswithyourhandheld
computer.
■Whenyou remove the batt eries, the built-in backup power of your
handheld computer maintains memory data for a period of up to
oneminute. Whenever you remove the batteries, replace them
immediately. If you encounter any difficulties in the course of
batteryreplaceme nt, 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 computer
doesnot 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, butn ot enough totu rn on yourh andheld computer. If
yourhandheld computer does not turn on when you press the
power button, you should replace the batteries immediately.
■If you leave drained batteries in your handheld computer for an
extendedperio d 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 computer. (See “Resetting your handheld
computer” later in this chapter for details.) After you reset your
handheldcomputer, perform a HotSync operation to restore the
data from your computer.
