Installation and setup
After installing the battery, you may be able to make and receive short calls.
For best performance, place the handset in the telephone base and charge for
16 hours before use.
You can keep the battery charged by returning the handset to the telephone
base after use. When the battery is fully depleted, a recharge takes about 12
hours. The average talk time on a fully charged battery is about eight hours and
the standby time is approximately five days. Actual battery life depends on usage
conditions and age of battery.

securely insert the

the battery should last around
one year. This may depend on
usage.
Choose a central location close to a telephone jack and an electrical outlet not
controlled by a wall switch. The telephone base can be placed on a flat surface or
mounted on a standard wall plate. For optimum range and better reception, place
the telephone base in a high and open location.
Avoid placing the telephone base too close to:
• Communication devices such as: personal computers, computer routers, televi-
sion sets, VCRs, wireless routers (wireless broadband, wi-fi, or 802.11) or other
cordless telephones.
• Excessive heat sources.
• Noise sources such as a window with traffic outside, motors, microwave ovens,
refrigerators, or fluorescent lighting.
• Excessive dust sources such as a workshop or garage.
• Excessive moisture.
• Extremely low temperatures.
• Mechanical vibration or shock such as on top of the washing machine or work bench.
