Battery considerations
Please note the following considerations when replacing the batteries
in your handheld computer:
■
Under normal conditions, your 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 computer off after a period of
inactivity. See “General preferences” in Chapter 7 for more
information.
■
If the batteries become low in the course of normal use, an alert
appears on the 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
computer off (so there is no screen display). Never remove the
batteries while your handheld computer is turned on.
■
When replacing the batteries, always use good quality batteries of
the same type. Use only alkaline batteries with your handheld
computer.
■
When you remove the batteries, the built-in backup power of your
handheld computer 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 computer
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 computer. If
your handheld 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
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 computer. (See “Resetting your handheld
computer” later in this chapter for details.) After you reset your
handheld computer, perform a HotSync operation to restore the
data from your computer.
