How to Prolong Battery Life
■ Use the Toshiba Pocket PC e400 with the AC adapter.
Under the following conditions where the power consumption will be
high, please use the AC adapter when:
■ Operating while connected to your computer.
■ Operating with a storage card or with any other optional equipment.
■ In addition,
■ Select the short power-off time in the setting menu to shorten the time
the unit will remain on if not used (see “ Customize Your Toshiba Pocket
PC ” on page 25).
■ Turn off the screen light.
■ Set the screen brightness to power saving mode and shortening the
light turn-off time (see “ Customize Your Toshiba Pocket PC ” on page
25).
■ Use your unit with an ambient temperature between 59°F and 77°F
(15°C and 25°C). This temperature range is the most effective for the
battery.
■ When you use the Toshiba Pocket PC e400 in high or low temperature
environments, the operable time is shortened due to the decrease of
the battery capacity.
Battery Life

temperature. It may shorten battery life.
For charging the battery, maintain an ambient temperature from approx.
41°F to 104°F (5°C to 40°C).
When the lamp glows orange or green, you can use the Toshiba Pocket

When the battery is completely charged, the Battery/Alarm LED color will
change to green.
If you have not used the Toshiba Pocket PC e400 for several days, its
