The SMH5 can be paired with up to three other headsets for Bluetooth Intercom conversation.
1. Turn on the two SMH5 headsets (A and B) that you would like to pair with each other.
2. Press and hold the Jog Dial of the headset A and B for 5 seconds until red LEDs of the both units start to flash rapidly. You will hear a voice prompt saying “Intercom pairing”.
3. Simply tap the Jog Dial of any one of the two headsets A or B (It doesn’t matter that you choose A or B) and wait until the LEDs of both headsets turn to blue and intercom connection is automatically established. The two SMH5 headsets A and B are paired with each other for intercom conversation. If the pairing process is not completed within one minute, the SMH5 will return to stand-by mode.
