For Best Performance
Operating Range
•
The range of operation depends on the topography of your office, weather, or usage
conditions, because signals are transmitted between the CS and the handset by radio
waves.
•
Normally, you get greater range outdoors than indoors. If there are obstacles such as
walls, noise may interfere with your telephone calls. In particular, high metal shelves or
reinforced concrete walls will restrict your operating range.
•
A handset may not work when it is too far from the CS depending on the structure of the
building.
•
We strongly suggest you hold the bottom half of the handset to ensure better call quality.
Because, the antenna is located in the upper half of the handset.
Noise
Occasional noise or interference may occur due to electromagnetic radiation from objects
such as refrigerators, microwave ovens, faxes, TVs, radios, or personal computers. If noise
disturbs your telephone calls, keep the handset away from these electrical appliances.
