Introduction
For best performance
Base unit location/noise
The base unit and handset use radio waves to communicate with each other. For maximum distance and noise-free operation, we recommend the following:
L Placing the unit away from electrical
appliances such as a TV, personal computer or another cordless phone.
L Placing the base unit in a HIGH and
CENTRAL location with no obstructions such as walls.
L Raising the antenna vertically. L If you use the handset near a microwave
oven which is being used, noise may be heard. Move away from the microwave oven and closer to the base unit.
L If you use the handset near another
cordless phone’s base unit, noise may be heard. Move away from the other cordless phone’s base unit and closer to your base unit.
L The maximum calling distance may be
shortened when the unit is used in the following places: Near obstacles such as hills, tunnels, undergrounds, near metal objects such as wire fences, etc.
L Operating near 2.4 GHz electrical
appliances may cause interference. Move away from the electrical appliances.
