TECHNICAL INFORMATION
REN Number:
The Ringer Equivalence Number (REN)
assigned to each terminal’s device
provides an indication of the maximum
number of terminals allowed to be
connected to a telephone interface.
The REN number of this phone is
located on the bottom of the base unit.
The termination on an interface may
consist of any combination of device
subject only to the requirement that
the sum of the Ringer Equivalence
Numbers of all the devices does not
exceed 5.
CAUTION
This product is intended for use in the
USA and CANADA only. Sale or use
in other countries may violate local
laws.
Cordless telephones use radio
frequencies to allow mobility. This
affects the performance of your
phone.
1. NOISE
Electrical pulse noise is present in
most homes at one time or another.
This is most intense during electrical
storms. Certain kinds of electrical
equipment, such as light dimmers,
fluorescent bulbs, motors, fans, etc.,
also generate pulse noise.
Because radio frequencies are
susceptible to this, you may on
occasion hear pulse noise through
the handset. This is usually only a
minor annoyance and should not be
interpreted as a defect of the phone.
2. RANGE
Because radio frequencies are used,
the location of the base station can
affect the operating range of the
phone. Try several locations and
choose the one that gives the
clearest signal to the handset.
(Turning in a circle while holding the
handset may also increase the
operating range.)
3. INTERFERENCE
Electronic circuits activate a relay to
connect the unit to your telephone
line. These electronic circuits operate
in the radio frequency spectrum.
While several protection circuits are
used to prevent unwanted signals,
there may be periods when these
unwanted signals enter the base
station. You may hear a click or hear
the relay activate when you are not
using the cordless handset. If this
occurs frequently, you can minimize
or eliminate the problem by lowering
the height of the base station or
relocating the base station. It may also
be helpful to change the operating
channel and/or the security code
setting.
Operation is subject to the following
two conditions: (1) this device may
not cause interference, and (2) this
device must accept any interference,
including interference that may cause
undesired operation of the device.
