SECTION 3FCC REGULATORY INFORMATION
3.1 Part 15 Compliance
This device complies with part 15 of the FCC rules. Ope
following two conditions: (1) This device may not cause harmful interference,
and (2) This device must accept any interference received, including
interference that may cause undesired operation. Privacy of communications
may not be ensured when using this phone.
ration is subject to the
3.2 Privacy Information
Cordless telephones are radio devices. Communicat
ions 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
___________________________________________________________________________________

term
D
Cordless DECT Document Revision 1
___________________________________________________________________________________
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.
3.3 Radio Interference Information
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 hea
r other voices or distracting
transmissions on your telephone, you may be receiving radio signals for
another cordless telephone or other source of interference. If you cannot
eliminate this type of interference, you need to change to a different channel.
Finally, it should be noted that some cordless telephones operate at
freq
uencies 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.
Radio interference causes interruptions in conversa
tion. 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 National Technical Assistance Center.

SECTION 1 CHECKING THE PACKAGE CONTENTS
You should have received the following items:
T DTL-RPT-1 DECT repeater
T AC adapter
T Mounting screw and wall anchor
SECTION 2HOW IT WORKS
The DTL-RPT-1 repeater lets you extend the coverage area of your D
Cordless telephone system in all directions, including up and down. If the repeaters
are installed so their coverage area overlaps the coverage area of the base, the base
can hand-off calls to the repeaters as the user moves from one coverage area to
another. When connected to the repeater, the mobile handset operates the exact
same way as it does when connected to the base, and the hand-off from the base to
the repeater can be completely invisible to the end user, even during an active call.

4.1 Automatic Registration
The repeater seeks out the base with strongest DECT/GAP signal and
aut
omatically registers to that base.
1. Make sure the repeater is powered off (i.e., the AC power adapter is not
connected).
2. Set the base into registration mode. (Consult the owner's manual that
came with yo
ur base station for more information).
3. Use the AC adapter to connect the repeater to a standard 120 V AC
out
let. (Do not use a power outlet controlled by a wall switch.) The LED
on the repeater flashes briefly, then remains on and steady.
If the LED continues to flash, try registering the repeater again.
The repeater is now registered to this base and is ready to use.
You can safely disconnect the power and move the repeater to the selected
lo
cation; the repeater will stay registered to the base.
4.2 Registration for a Daisy-Chain Layout
Registering the repeaters to operate in
requires network administrator access and configuration software. Contact
your installer or refer to the DTL-RPT-1 Administrator's Guide (provided with
the configuration software) for more information.
4.3 Registering to a Different Base
Once the repeater is registered, you need to reset it before you can change
registration to a different base. If you want to reset the repeater and clear
the

SECTION 5INSTALLING THE REPEATER
5.1 Finding the Right Location
To get the best operating conditions for the repeater, it is important to place it
correct
Place the repeater as high as possible, but at least 6 feet off the ground.
Make sure you have good reception from the base.
Make sure the location is close to a standard 120 V AC power outlet.
Allow at least 35 feet between repeaters (if you are installing repeaters
Avoid sources of electrical interference, such as hi-fi systems, office
ly. Here are a few tips for placing repeaters:
Never install electrical cords across a traffic area: they can create a trip
hazard or become damaged and create a fire or electrical hazard.
across multiple floors, remember to allow 35 feet vertically, also).
equipment or microwave ovens.
Avoid heat sources and direct sunlight.
Avoid things that can interfere with radio signals, such as metal doors,
thick walls, niches and cupboards.
5.2 Map the Base Coverage Area
To find the best location for the repeater, you need to determine the base
covera
ge area. Stand near the base and make a call. Walk away from the
base with the handset, and make a note where the signal becomes weaker.
The optimum location for the repeater is as far from the base as possible while
still maintaining a "good" signal, or just inside the location where the signal
became weaker.

5.3 Test the Location
To test the location, plug the AC adapter into the repeater, then hold the
rep
eater in the place where you plan to mount it. The LED should remain on
and steady, indicating that the repeater has a good signal from the base.
If the LED flashes, the repeater is not getting a good signal. The repeater may
too far away from the base, there may be interference from electronic
be
devices, or the signal might be blocked by thick walls or metal objects. Try
moving the repeater to another location.

3. At the screw location, use a 3/16ths drill bit to make a pilot hole
ap
proximately one inch deep.
4. Place the wall anchor into the pilot hole and tap it gently with a hammer
un
til the anchor is flush with the wall.
5. Insert the mounting screw into the anchor, leaving approximately 1/4
in
ch space between the screw head and the wall.
