Do not mutilate, puncture, or dispose of batteries in fire. The batteries can burst or explode, releasing hazardous chemicals. Replace batteries only with the types recommended in this User’s Guide. Discard used batteries according to the manufacturer’s instructions.

Installing the backup battery

The backup battery protects your data when the main battery runs out of power. The backup battery does not provide enough power to operate your HP Jornada, but it will preserve your data while you replace the main battery or while you connect to ac power to recharge. The 3-V CR2032 coin-cell backup battery is attached to the HP Jornada Quick Start Card. Follow the procedure outlined below to install the backup battery.

To prevent loss of data, replace the backup battery as soon as a warning message appears on your screen indicating that backup battery power is low. (For detailed instructions on replacing the backup battery, see the Managing battery power section in chapter 7.)

To install the backup battery

1.Remove the backup battery from the HP Jornada Quick Start Card.

2.Turn the Jornada upside-down and open the CompactFlash door.

3.Use the tip of the stylus to carefully open the backup battery cover.

4.Insert the battery printed side up in the battery compartment.

5.Using the stylus tip, close the backup battery cover to secure the coin-cell battery, and then close the CompactFlash door.
