Important battery information
Use the battery pack only as directed. Heat or cold reduces the
performance and service life of the batteries. Handsets with hot or cold
batteries can become temporarily out-of-service, even if the batteries are
fully charged. Charge the batteries only with the DECT 4027 and 4070
Handset charger supplied with the handset.
Charging guidelines
Observe the following guidelines when you charge your handset:
• Charge the battery for at least 6 hours before you use the handset for
the first time. This protective measure extends the service life of the
batteries.
• The batteries attain maximum power output only after several
charging and discharging cycles.
• Do not leave the handset connected to the charger for more than a
month without using it.
• You can charge and discharge the batteries hundreds of times, but
eventually they wear out. If the operating time (talk and standby time)
becomes significantly shorter than usual, replace the batteries.
• To maintain optimum operating time, periodically discharge the
batteries by leaving the handset off the charger and switched on, until
the handset switches itself off. Use only this method to discharge the
batteries. You can disable the display to accelerate battery discharge.
For more information about configuring power save, see “Configuring
power save” (page 167).
• Extreme temperatures influence the charging capability of the
batteries.
