What Do I Need To Know About Batteries - HandEra 330 User Manual

What do I need to know about batteries?

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.
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 or a lithium-ion battery pack
purchased from HandEra.
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.
