Battery life
� With a fully-charged battery, you can use your PEG-SJ20 CLI� handheld for approximately 15 days* or your PEG-SJ30 CLI� handheld for approximately 12 days*.
* Based on an average of 30 minutes use of PIMs per day, with the backlight off.
� Battery life varies depending on the conditions and environment where you use your CLI� handheld.
Tips on conserving the battery
� Turn off the backlight under good lighting conditions. For turning off the backlight, see �Adjusting the screen� on page 24. � Change the automatic shut-off time setting so that your CLI� handheld will automatically turn off after a short period of inactivity. For details, see �Setting the automatic shut-off time� on page 165.
When your battery becomes weak
� When the battery becomes weak, a caution message appears on the screen. If this occurs, perform a HotSync® operation to back-up all the data of your CLI� handheld to your computer. Then charge your CLI� handheld. This helps prevent accidental data loss. � If your CLI� handheld does not turn on when you press the POWER button, charge your CLI� handheld immediately. � The remaining battery indicator does not always reflect the actual battery amount. The battery is designed to provide years of service under normal use. To prolong the battery�s life, charge it frequently even when it is not fully discharged. � You do not have to replace batteries. When the remaining battery indicator reads zero, charge your CLI� handheld immediately. Never disassemble your CLI� handheld to take out the battery.
When using peripheral devices
If a message appears that your CLI� handheld is low on battery, promptly discontinue the use of your CLI� handheld and charge it. If you continue to use the CLI� handheld without charging it, data stored on your CLI� handheld may be lost.
When the remaining battery indicator reads zero
If your battery drains and you leave your CLI� handheld in an uncharged state for an extended period of time, all of the stored data will be erased. Sony suggests you charge your CLI� handheld frequently.
