Privacy
Cordless telephones are radio devices. Communications between the handset and
base of the cordless telephone are accomplished by means of radio waves which are
broadcast over the open airways. 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.
SECTION 4IMPORTANT ELECTRICAL CONSIDERATIONS
Do not attempt to unplug any appliance during an electrical storm.
Unplug all electrical appliances when you know an electrical storm is approaching.
Lightning can pass through your household wiring and damage any device connected
to it. This telephone is no exception.
Caution:
Changes or modifications to this product not expressly approved by
NEC Unified Solutions,
other than as detailed by this manual, could void your authority to
operate this product.
The telephone is designed to achieve a maximum range of up to 350 feet (depending
upon the environment), by transmitting and receiving according to the highest
specifications set forth by the FCC. We have rated this phone to operate at a
maximum distance with the qualification that the range depends upon the
environment in which the telephone is used. Many factors limit range, and it would be
impossible to include all of the variables in our rating. The maximum range rating of
this telephone is meant to be used as a means of comparison against other range
claims.
Telephone Line Problems
The FCC has granted the telephone company the right to disconnect service in the
event that your telephone causes problems on the telephone line. Also, the
telephone company may make changes in facilities and services which can affect the
operation of your unit. However, your telephone company must give adequate notice
in writing prior to such actions to allow you time for making necessary arrangements
to continue uninterrupted service.
If you are having trouble with your telephone service, you must first disconnect your
telephone to determine if it is the cause of your problem. If you determine that it is the
cause, you must leave it disconnected until the trouble has been corrected.
Radio Interference
Radio interference may occasionally cause buzzing and humming in your cordless
handset, or clicking noises in the base unit. This interference is caused by external
sources such as TV, fluorescent lighting, or electrical storm. Your unit is NOT
DEFECTIVE. If these noises continue and are too distracting, check around your
office to see what appliances may be causing the problem. In addition, we
recommend 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 you consistently hear other voices or distracting
transmissions on your telephone, you may be receiving radio signals for another
cordless telephone or other source of interference.
Finally, it should be noted that some cordless telephones operate at frequencies that
may cause interference to nearby TVs and VCRs. To minimize or prevent such
interference, the base of the cordless telephone 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.
More than One Cordless Telephone
If you want to use more than one cordless telephone in your office, they must operate
on different channels and more than 20 feet apart.
If more than eight DTL-8R-1s are used in the same area, there is a possibility that the
following problem occurs:
TDifficulty connecting the Handset with the Base Unit
TSome noises can be heard during conversation
The DTL-8R-1 is limited to five RF channels. The RF channel is changed
automatically to find the best channel.
Depending on your environment, the maximum number of cordless devices used
without interference varies.
Multiple base and handset units should not be closer than 20 feet at any time.
Radio interference causes interruptions in conversation. When this happens, your unit
is not defective. When noise continues, move to a different location while you talk.
(You might even need to move the base unit.) When the situation persists, contact the
National Technical Assistance Center (NTAC).
Congratulations on your purchase of the D
