See here the Quickinstallation Guide for the C52-SP: QIG_C52_2017001.pdf

This guide will show you how to register (pairing) and deregister  the C52-SP Speaker/Microphone and an A230 DECT dongle.


Scenarios

For different cases you might need different solutions. Ultimately, however, you only need one of the two listed procedures to register or deregister.

  1. Case 1: You have lost the A230 dongle or it is defective. As a result, the dongle to which your C52-SP was paired is no longer available.
    1. Solution 1: You buy a new A230 dongle. This is unregistered. Here you simply have to go through the pairing procedure below.
    2. Solution 2: You receive another A230 dongle that you have already used. Here you should first go through the deregistration procedure and then the pairing procedure for both devices (Dongle and C52-SP).

  2. Case 2: You have lost the C52-SP or it is defective. You will receive a replacement device.
    1. Solution 1: To use the existing "old" A230 dongle, it must be deregistered and then the pairing procedure must be carried out.


Deregistering/Unpair the A230

To deregister a A230 DECT Dongle please follow these instructions:

  1. Press the key on the dongle for 10 seconds to enter deregistration mode.
    After 4 seconds of pressing the red LED starts to double-flash; at the end of the 10     seconds the LED starts to flash red rapidly, indicating that the dongle has entered deregistration mode.
  2. Then release the key and press it again for 1 second to confirm deregistration.
    The LED turns green for three seconds, turns off for one second     and then shows steady red light.


Deregistering/Unpair the C52-SP

  • To disconnect, hold the "Register" button for 10 seconds, release and immediately press the button again.
  • If everything is done correctly, the unit should stop flashing and a moment later, all the lights should turn yellow for a few seconds and then turn off.
  • Now the connection between the DECT dongle and the C52-SP is successfully disconnected.


Pairing

Make sure that the C52-SP is charged and the power supply is connected and within 30 cm of the A230.

When the C52-SP is not paired, it blinks slowly yellow.
  1. First press the button on the A230 dongle for 4 seconds, it starts blinking red.
  2. Then press and hold the registration button on the bottom of the C52-SP until the LEDs blinking red/green.
  3. If the process was successful, all LEDs on the C52-SP light up green and then turn off. The LED on the A230 also stops flashing.
  4. You can test the function by pressing the "call answer button". If the C52-SP is correctly paired, the phone will now start a call and you will hear a dial tone from the C52-SP's speaker. At the same time all LEDs are permanently lit in green.
  5. If the C52-SP continues to flash yellow, go back to steps 1 and 2 (sometimes it does not work the first time).
