Caution: Overheated battery
If an overheated battery is detected, charging will suspend.
• Periodically clean the charge contacts on both the charger and handset.
• Do not leave a battery where it could be subjected to extremely high temperatures.
• Do not charge battery when the ambient room temperature is above 35°C/95°F or
below 0°C/32°F.
• Do not replace batteries in potentially explosive environments, such as rooms where
flammable liquids or gases are present.
• Do not charge batteries unless you use the approved power adaptor and the proper
batteries.
• Use only rechargeable LI-Ion Battery Pack in the Spectralink DECT 7000 Series
Handset.
• Do not disassemble, short circuit or dispose of in fire.
• Do not let battery or power adaptor come into contact with conductive metal objects.
• Power handset off before removing battery.
Note: Battery Life
How intensively you use your handset determines how frequently the battery will need
to be charged. Under intensive use, battery replacement may be needed during a
normal shift.
Certain handset features require more battery capacity than others. Any battery life
estimates are highly dependent on phone usage and the features that are deployed as
well as the environment itself.
After a length of time, batteries will lose the ability to maintain a charge and to perform
at maximum capacity and will need to be replaced. This is normal for all batteries.
