For Best Performance

Handset Battery Charge

A rechargeable Nickel-Metal Hydride (Ni-
MH) battery powers the cordless handset.
Charge the battery for about 8 hours
before initial use (p. 16). Make sure the
handset faces forward as shown.
If you charge the discharged battery, it will be
charged quickly. In that case the handset
may feel warm. This is normal.

Base Unit Location/Noise

Calls are transmitted between the base unit and the cordless handset
using wireless radio waves. For maximum distance and noise-free
operation, the recommended base unit location is:
Away from electrical appliances
such as a TV, personal computer or
another cordless phone.
Raise
the antenna.
Note:
—If you use the cordless handset near a microwave oven which is being used,
noise may be heard from the receiver. Move away from the microwave oven and
closer to the base unit.
— If you use the cordless handset near another phone's base unit, noise may be
heard. Move away from the other cordless phone's base unit and closer to your
base unit.
