BATTERIES

The Lithium ion battery is rechargeable with an
operating time of up to 2.5 hours (C352) or 2
hours (C360) depending on active power man-
agement features and user activity levels. If the
internal Lithium ion Battery goes dead, you
must install the AC adapter or shut down and
install a charged battery. (See page 107 for
replacing the battery.)
The Lithium ion battery operating time may
become shorter than the reference value if it is
used under the following conditions:
When used at temperatures that exceed a low
of 5°C or a high of 35°C. High temperatures
not only reduce charging efficiency, but can
also cause battery deterioration. (The Charg-
ing icon on the Status Indicator panel will
flash when you try to charge a battery that is
outside its operating temperature range.)

The battery charging capacity is reduced as the

Using the AC adapter will conserve your battery
