74 Battery Care and Maintenance Preliminary Draft
When the phone is in power-save mode, you cannot make or
receive calls. “Power Save Mode” and the No Signal icon
appear on the display.
The phone periodically rechecks for a signal. Press any key to
manually check for service. When the phone finds a signal, it
automatically switches out of power-save mode and displays the
Signal Strength icon at the top of the display.
Caring for battery
■ To reduce unnecessary drain on your battery, turn backlight to
“always off” (see page 52.)
■ Do not disassemble or short-circuit the battery.
■ Keep the metal contacts at the base of the battery clean.
■ If you have not used an internal or external battery for more
than a month, recharge it before using it.
■ Replace the internal battery when it no longer maintains a
charge. Return the old battery to your local QUALCOMM
service center.
■ Do not use any battery in direct sunlight or in places with high
humidity, such as the bathroom.
■ Never dispose of any battery in or by a fire. It could explode.
■ Do not charge any battery if the temperature is below 32ºF
(0ºC) or above 122ºF (50ºC).
■ Do not store any battery in hot areas for long periods of time.
Follow these storage guidelines:
❑ under 1 month: -4ºF (-20ºC) to 140ºF (60ºC)
❑ over 1 month: -4ºF (-20ºC) to 113ºF (45ºC)
