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 sup-
plied rechargeable battery or
replacement battery (model 27910,
part number 89-0099-00-00) or

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.
