Yealink DECT Repeater RT30

The Yealink DECT Repeater, RT30, can be deployed to extend the range of the W52P IP DECT phone to cover areas where reception was previously not available in accordance with Digital Enhanced Cordless Telecommunication (DECT) standards. All the usual handset functions are supported by the base station in the extended radio range. The repeater, base station and cordless handset employ wireless connection. In this section we will describe the process to register/de-register a repeater to a base station and some tips will be provided on how to deploy a repeater.

Connect the power for the repeater

1. Connect the RT30 to a power outlet using the provided cable and USB power adapter

Mount to a wall

Attach the base stand

Align the snap-fits with the corresponding holes and push forward, snapping them into the holes.

Setting up a repeater

If the radio link level of RT30 is excellent to good, each repeater can have up to two calls (external and internal calls) at any time. The repeater can be used to extend the range (up to 300m in unobstructed outdoor areas and up to 50m inside buildings). The automatic handover process is seamless. If the repeater is placed properly (overlapping the coverage of the base station), the handsets can move freely within the total coverage while on a call. The repeater does not increase the quantity of call paths and it shares the call paths with the base station.

Star Mode:

Up to 6 repeaters can be registered to one base station to extend the range in a star layout. All repeaters must be installed within the base station coverage.

Cascade Mode:

Cascade Mode allows you to "daisy chain" to extend range in a single direction. This is in addition to the Star Mode that is available with the W52P.

Note: Whilst Cascade setup is supported on the RT30, this is only supported on the Yealink W73P devices; this is not supported with the Yealink W52P devices.

The maximum number of handsets that can be registered to your base station is not affected by the repeater. The repeater can be used to extend the coverage range in all directions, allowing several floors to be covered.

Registering the repeater

If you want to register more than one repeater, in order to avoid ID conflict, we recommend that you put the repeaters closer to the base station and register the repeaters one by one.

  1. Plug the repeater into a power outlet. The Power LED will turn green and the DECT LED will flash red.
  2. Set the handset into RT30 Repeater Mode by going to "Settings→ System → Settings → Repeater Mode".
  3. Set the base station in registration mode by long pressing the paging key on the base station until the first LED flashes green.
  4. If the base station is found, the DECT LED will flash orange. When the DECT LED turns green/orange, the registration to the base station has been successful.

ID Modification

If you want to register more than one repeater, in order to avoid ID conflict, we recommend that you put the repeaters closer to the base station and register the repeaters one by one.

  1. Press the program key to confirm the ID.
  2. Long press the program key for around 7 seconds to enter the ID modification mode. When in ID modification mode, both the Power and DECT LEDs turn red.
  3. Press the program key to enter the new ID. Pressing it once indicates that the ID is one, twice means it is two etc. The number of times that the Relay LED flashes indicates the entered ID.
  4. Long press the program key for around 3 seconds to confirm the ID. The repeater will then re-register.
  5. De-registration


  1. Long press the program key and reconnect the power adapter
  2. Hold the program key until the three LEDs turn red. When the DECT LED flashes red, the de-registration is successful.


  1. To achieve optimum performance for the repeater, it is important to find an appropriate location.
  2. Hold the handset and stand near the base station.
  3. Make a call and then call the handset away from the base station.
  4. Make a note where you start to hear noise on the line, which indicates that the signal strength is getting 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 noise became noticeable.


  • Choose a raised position for both the base station and the repeater wherever possible.
  • When positioning the repeater, avoid obstacles that can interference with radio transmission, such as thick walls and metal structures.
  • Place the repeater away from other electrical appliances, such as microwaves, wi-fi equipment and computers.
  • Keep a minimum of 10 meters between multiple repeaters to avoid coverage overlapping.
