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 OFF).

• Place your DECT base unit into registration mode by pressing and holding the 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.

cell station. This means that the PBX cell station does not have to be placed into site survey mode.

2) When using more than 1 repeater in site survey mode simultaneously, please ensure repeaters are set to different channels.

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.

Serial Repeater ID programming continued.

• 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
