Installation and setup
After installing the battery, you may be able to make and receive short calls.
For best performance, place the handsets in the telephone base or the charg-
er and charge for 16 hours before use.
You can keep the battery charged by returning the handsets to the telephone
base or the charger 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.
Caution: Use only the supplied
rechargeable battery or replacement
battery (model 27910, part number
89-0099-00-00) or equivalent. To

usage.

Choose a central location close to a telephone jack and a power outlet not
connected to a wall switch. The telephone base can be placed on a flat sur-
face 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, tel-
evision 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.
