active vibration alarm and
Bluetooth operation are features that can specifically shorten standby
and talk times.

Installation
• If you ever notice liquid leaking out, unusual odour, build-up of heat, discolouration, deformation
or any other abnormal condition when you use, charge or store the battery, remove the battery
immediately from the handset and keep it away from naked flames.
• The battery fluid can damage your sight. If at any time battery fluid accidentally gets into your
eyes, rinse your eyes immediately with clean tap water and contact a doctor.
• If the battery is to be used by children, make sure a responsible adult instructs the children in the
precautions and proper handling, and make sure the children handle the battery correctly.
• If battery fluid accidentally gets onto your clothing or skin, rinse the affected place immediately
with pure tap water. Prolonged contact with battery fluid can lead to skin inflammation.
Precautions during use
• The battery is designed for use with these handsets only.
• Only use the charger cradle supplied for charging.
• A new battery is not charged so you need to charge it before using for the first time.
• Using the battery in a cold environment can shorten the expected operating life of a full charge.
Charge the battery at a location with a temperature between 10° C and 35° C. Charging outside
this temperature range can lead to a longer-than-usual charging time or even to failure of the
charging process.
• An extremely short operating time after a full charge indicates that the lifetime of the battery has
expired. Replace the battery.
• Never wipe the battery with thinners, benzene, alcohol, or other volatile substances, or chemically
treated cloths. These can cause deformation of the battery and malfunction.
