Precautions
Battery life
• With a fully-charged battery, you can use your PEG-SJ20 CLIÉ handheld
for approximately 15 days * or your PEG-SJ30 CLIÉ 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 CLIÉ 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 CLIÉ 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 CLIÉ handheld to your computer. Then charge your CLIÉ
handheld. This helps prevent accidental data loss.
• If your CLIÉ handheld does not turn on when you press the POWER
button, charge your CLIÉ 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 CLIÉ handheld immediately. Never
disassemble your CLIÉ handheld to take out the battery.
When using peripheral devices
If a message appears that your CLIÉ handheld is low on battery, promptly
discontinue the use of your CLIÉ handheld and charge it.
If you continue to use the CLIÉ handheld without charging it, data stored on
your CLIÉ handheld may be lost.
When the remaining battery indicator reads zero
If your battery drains and you leave your CLIÉ handheld in an uncharged
state for an extended period of time, all of the stored data will be erased.
Sony suggests you charge your CLIÉ handheld frequently.
