Operating Range
• The range of operation depends on the topography of your office, weather, or usage
conditions, because signals are transmitted between the base unit and the handset/
desk phone 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/desk phone may not work when it is too far from the base unit 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/desk phone away
from these electrical appliances.
