Recommended Usage Guidelines for Cordless Phones

In ideal conditions, multiple spread spectrum type cordless phones (Cordless II can be utilized in the
same environment. However, due to the possible interference problems caused by the bases being
placed in close proximity to each other, we recommend the following:
Spread Spectrum Phones (Cordless II P /N 730088)
Where users require greater range on the cordless phones and 3 or less cordless phones are being used
at a specific site, we recommend using the spread spectrum cordless phone.
FM Modulation Phones (Cordless Lite II P /N 730087)
Where more than 3 cordless phones are to be used at one specific site, we recommend using the FM
modulation cordless phones which have 30-channel capability.
Note: The range of the phones depends largely on the environmental factors, such as the building
structure, the size of the room, RF interference and other electronic equipment installed in the same
area. For optimum range and performance, we suggest the following:
• Place the base units at least 15 feet apart. The performance of the phones become more stable when
the distance between the bases is greater.
• Place the base unit in the center of the coverage area.
• If the phone will also be used in an outdoor area, like a parking lot, install the base unit in an area
close to the window.
• If a phone experiences interference and noise, press the channel key to select another channel.
