Figure 1: Installing the battery pack
Important battery information
Use the battery pack only as directed. Heat or cold reduces the
performance and service life of the batteries. It is possible that a handset
with hot or cold batteries can be temporarily out of operation even if the
batteries are fully charged.
Charging the batteries
Place the handset in the charger.
Charging guidelines
• Charge the batteries for approximately five to six hours before using
the handset for the first time. This protective measure extends the
service life of the batteries.
• The maximum power output is attained only after three to five
charging and discharging cycles.
• Do not leave the handset connected to the charger longer than one
month without using.
• The batteries can be charged and discharged hundreds of times, but
eventually they wear out. If the operating time (that is, talk and
standby time) is significantly shorter than usual, replace the batteries.
CAUTION
The batteries can become hot during the first charge
cycle.
