Cordless telephones are radio devices. Communications between the handset and base of the cord-
less telephone are accomplished by means of radio waves which are broadcast over the open air-
ways. Because of the inherent physical properties of radio waves, communication can be received
by radio receiving devices other than your own telephone unit, consequently, any communications
using the cordless telephone may not be private.
Radio Interference
Radio interference may occasionally cause buzzing and humming in your cordless handset or click-
ing noises in the base unit. This interference is caused by external sources such as TV, fluorescent
lighting, or electrical storms. Your unit is not defective. If these noises continue and are too distract-
ing, check around the office to see what appliances may be causing the problem, In addition, it is
recommended that the base not be plugged into a circuit that also powers a major appliance because
of the potential of interference. For best performance, ensure that the antenna on the base unit is
fully extended.
In the unlikely event that other voices or distracting transmissions are heard on the phone, radio sig-
nals for another cordless telephone or other source of interference may be the problem. If this type
of interference cannot be eliminated, change the telephone to a different channel.
If should also be noted that some cordless telephones operate at frequencies that may cause inter-
ference to nearby TVs and VCRs. To minimize or prevent such interference, the base unit should
not be placed near or on top of a TV or VCR. If interference is experienced, moving the cordless
telephone farther away from the TV or VCR will often reduce or eliminate the interference.
Multiple Cor
dless Telephones
If you want to use more than one cordless telephone in the same office, they must operate on differ-
ent channels. Press the channel key to select a channel that provides the clearest communication.
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, the following is recommended:
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:
1. 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, the following is suggested:
2. 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.
3. Place the base unit in the center of the coverage area. If the phone will also be used in an out-
door area, like a parking lot, install the base unit in an area close to the window.
4. If a phone experiences interference and noise, press the channel key to select another channel.
