Panasonic KX-TD7580 Operating Instructions Manual page 15

For Best Performance
Operating Range
1) The range of operation depends on the topography of your office, weather or usage conditions,
because signals are transmitted between the Cell Station (CS) and the Handset by radio waves.
2) Normally, you will 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 shorten your operating range.
3) A Handset may not work when it is too far from the CS depending on the structure of the building.
Noise
Occasional noise or interference may occur due to other sources of electromagnetic radiation, such as
refrigerators, microwave ovens, faxes, TVs, radios, or personal computers. If noise disturbs your
telephone calls, keep the Handset away from other electrical appliances.
