SECTION 2IMPORTANT ELECTRICAL CONSIDERATIONS
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 repeater is no exception.
Changes or modifications to this product not expressly approved by NEC Corporation
of America, or operation of this product in any way other than as detailed by this
manual, could void your authority to operate this product.
SECTION 3FCCREGULATORY INFORMATION
3.1 Part 15 Compliance
This device complies with part 15 of the FCC rules. Operation is subject to the
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.
Certification numbers:
FCC ID: AMWUU228
Industry Canada IC: 513C-UU228
Do not attempt to unplug any appliance during an electrical storm.

3.2 Privacy Information
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.
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 hear 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
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.
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 National Technical Assistance Center.

SECTION 2CHECKING THE PACKAGE CONTENTS
You should have received the following items:
repeater
AC adapter
Mounting screws and wall anchors
SECTION 3HOW IT WORKS
The DTL-RPT-2 Repeater repeater lets you extend the coverage area of your Dterm
DECT 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.

Configurations
Each base supports up to six repeaters, so you can extend coverage in all directions,
including through floors and ceilings.

Issue 1.0 Dterm Cordless DECT
In addition, the DTL-RPT-2 Repeater supports a sequential or "daisy chain" layout to
extend coverage in a single direction. Up to three repeaters can be installed in
sequence.
When a repeater powers on, it searches for signals from the base and any other
repeaters registered to the same base. The repeater will automatically connect to the
strongest available signal. You can combine "star" and "daisy chain" layouts to create
a wide variety of coverage configurations, as long as you have no more than six
repeaters per base unit.

SECTION 4SETTING UP YOUR REPEATER
Setting up the repeater involves four basic steps:
1. Install the AC adapter on the repeater unit.
2. Register the repeater to the base.
3. Position the repeater at the proper installation site.
4. Install the repeater in its final location.
Use ONLY the power adapter that came with your repeater. A different power
adapter may cause an electrical hazard or damage the repeater.
You can register up to six repeaters to a base. Repeat these steps as needed.
These procedures refer to items on the back of the DTL-RPT-2 Repeater:

During registration, the LED on the front of the repeater will blink. The table explains
what the LED blink patterns indicate.
SECTION 5INSTALLING THE AC ADAPTER
1. Using both thumbs, press down on the raised ridges of the adapter cover on the
repeater until you hear a click.
2. Being careful not to angle the cover, gently pull to remove it.
Table 2-1 Repeater LED Patterns
State Meaning
Steady On The repeater is registered to a base and has a good signal
from that base (or another repeater registered to that
base).
Slow blink (one blink per
second) Standby mode. The repeater is not registered or cannot be connected to the registered base.
Flicker (2 rapid blinks per
second) The repeater is in registration mode (it is looking for a base to register to).

3. Insert the AC adapter connector into the yellow adapter opening. Thread the
cord according to the illustration.
4. Carefully replace the cover, and press until you hear it click. Do not angle it as
you replace it.
5. Use the AC adapter to connect the repeater to a standard 120 V AC outlet. (Do
not use an outlet controlled by a wall switch!) The LED on the repeater flashes
briefly, then remains on and steady.
SECTION 6ACTIVATE REGISTRATION MODE ON BASE
You need to activate registration mode on your base before you can register your
repeater to it. Refer to the Owner’s Manual for your base unit for registration
instructions.
You only have to activate registration on the base once, regardless of how many repeaters
you want to register (up to 6).
6.1 Register Repeater to Base
You can register up to six repeaters to each base. Repeat these steps as
needed for each repeater. The repeater seeks out the base with strongest
DECT/GAP signal and automatically registers to that base. Make sure no
other bases in range are in registration mode. If more than one base is in
registration mode at the same time, you cannot control which base the
repeaters register to.

Issue 1.0 Dterm Cordless DECT
Before you start the registration process, be sure you have:
A working base
A working handset registered to that base
Any repeaters you want to register to that base (you must complete the
registration process separately for each repeater).
At least one of the AC adapters supplied with the repeaters. If you have
multiple repeaters to register, you can power up one repeater, register it,
power it off, and then use that AC adapter for the next repeater. The
repeater remains registered to the base, even if power is disconnected.
Use ONLY the power adapter that came with the repeater. A different adapter
may cause an electrical hazard, or damage the repeater.
6.2 Registration
1. Press and hold the registration button on the base until the Power LED
on the base begins to blink.
2. On the back of the repeater, press and hold the registration button until
the repeater LED on the front settles into a slow blinking pattern. The
repeater is now in registration mode.
3. Release the button on the repeater and wait for the LEDs on the
repeater and base to stop blinking and remain steady on (this can take
about 60 seconds).
4. 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
location.; the repeater will stay registered to the base even if you
disconnect the AC adapter, or there is a power failure.
