When setting up the phone:
• Use only the rechargeable batteries supplied with this product
• Follow the battery installation instructions included with this guide
Note: That it takes two to three charging cycles for the batteries to reach their fully
charged state.
• Charge the batteries using only the charger stand supplied with this
product
In operation:
• It is normal for the batteries to become warm when charging.
• Discharge the batteries from time to time to prolong their service life.
To do this, do not place the phone back into the charger stand until the
batteries are completely or almost completely discharged. The battery
icon on the display will indicate when the batteries are low and an alert
tone is sounded every three minutes.
• Only use batteries and charging units approved by the manufacturer.
• If you do not intend to use the phone for an extended period, the batter-
ies should be removed from the handset.
• Store batteries at room temperature. Above average temperatures tend
to reduce the service life of batteries.
• Do not throw away or incinerate used batteries. Take them to an
appropriate collection point for recycling or send them back to your sup-
plier or distributor.
The batteries included with the 6757i CT handset are designed to provide
up to four hours talk time and ninety six hours standby time. Actual
battery performance can be affected by a wide variety of environmental
and user factors.
