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.
