Overview
A repeater is used when you need to extend the range of your cordless DECT
telephone or PBX cell station, to include areas where reception was previously not
available. The repeater extends the range in all directions, allowing several floors to
be covered.
Up to 6 repeaters can be registered at a DECT base unit, and up to 18 repeaters
can be registered at a PBX cell station (when utilising Serial Repeater ID
Programming).
Please note : The number of simultaneous calls on a Cell Station is reduced by
adding a repeater. This is by design. Each repeater is controlled using one speech
path. The repeater can support up to a maximum of two handsets.

Automatic Registration
Automatic registration cannot be performed if the repeater is already registered to
another base unit or cell station. Please follow the DE-REGISTRATION procedure
on page 10 before attempting Automatic Registration.
•
Ensure that the repeater is switched off
(disconnect the AC adaptor) (both LEDs are

button for 10 seconds. This step is not necessary for registration to PBX cell
stations.
Power on the repeater, by connecting the AC
adaptor. The red LED will light for 2 seconds,
and then the green LED will flash slowly. This
indicates that the repeater is searching for
the cell station or base unit.
•
When the repeater has found the cell station
or base unit, the green LED will go steady
ON.
Note: It may take up to 60 seconds for the
repeater to register with the cell station or
base unit.
•

If after 60 seconds the registration has not
completed, the red LED will go steady ON,
indicating that registration has been
unsuccessful. In this case the registration
must be repeated. Power off the repeater and
start again.
Please note :1) Manual registration procedure may be required if the repeater is
used with unlisted products.
2) We recommend that you power down any cell station that you do
not wish to connect to the Repeater prior to Registration.

Manual Registration continued.
•
Press ‘off hook’ on the handset. The
green LED will go steady ON.

Enter a unique identifying number on the handset keypad for each repeater
registered. The identifying number can be 2 to 7 for domestic DECT products,
and 000 to 255 for PBX DECT products. The digit will display on the handset
screen.
The green LED will flash to correspond
with the dialled digit. i.e digit 5 will
cause the green LED to flash 5 times.
For PBX use the digit 0 will cause the
green LED to flash 10 times. i.e digits
025 will cause the green LED to flash
10 times for ‘0’, then a delay of 2
seconds, then flash 2 times for ‘2’, then
a delay of 2 seconds, then flash 5 times
for ‘5’. You do not have to wait for the
confirmation flashes when registering.
•
Dial “*” on the handset to store the
identifying number to memory. The
green LED will go off for 1 second.
If the identifying number entered is
already assigned, the red LED will light
for 1 second. A new identifying number
must then be entered followed by “*”.
The green LED will then flash slowly for
a short period of time before going
steady ON. Registration is complete.
•
If the registration is not successful, the red
LED will turn steady ON. In this case, repeat
the registration process.

Serial Repeater ID programming (PBX option only)
This function is used to control up to 3 repeaters in a chain configuration on a PBX
system. To ensure correct operation (and to avoid circular linking), each repeater
must be assigned a different chain-level (1 – 3). The first repeater (nearest the cell
station) is assigned chain-level 1, each additional repeater will then be assigned an
incremental number (up to 3), the highest number being assigned to the repeater
furthest removed from the cell station.
By default, a repeater is registered to chain-level 1 when first registered to a cell
station. After registration, the chain-level may be changed to a different chain-level.
Additional repeaters can be registered to operate on the same chain-level, this will
allow star configurations on each chain-level. All repeaters and cell stations must
have a unique Radio Part Number (R.P.N.).
There can be 6 repeaters per chain level. Chain-level 1 and chain-level 2 repeaters
can support another 6 repeaters.
There follows 2 example setups, showing both star and chain configurations.

Ensure that the repeater is switched OFF. (both LED’s are OFF)
Power ON the repeater.
Assign the repeater to a base by following either the manual or automatic
registration process.
•
•
Bring the repeater into close range of the repeater on the parent level (i.e. when
assigning a repeater to chain-level 3, the repeater must be brought into close range
with the repeater already set to chain-level 2.).
Press the switch the corresponding number
of times to set the chain-level.
(i.e. 3 times = chain-level 3 etc.).
The red LED flashes a number of times
corresponding to the chain level.
NB: Pressing the switch 4 or more times
corresponds to chain-level 1.
•
•
After two minutes from power ON, the new chain-level and Radio Fixed Part Identity
(R.F.P.I.) are then stored into the repeaters memory, and the repeater returns to
normal operation.
Please note : This function is not available for domestic DECT appliances, only
PBX.
