Here’s how to connect your Bluetooth speaker microphone to a Bluetooth adapter on your Motorola radio or equivalent.
What is required:
- Bluetooth Speaker Microphone (WV-BTH-900)
- Bluetooth Adapter
- Your Portable Radio
Pair Bluetooth Speaker Microphone to Bluetooth Adapter
1. Before you begin, make sure your portable two-way radio is powered off.
2. Attach the Bluetooth adapter to the side of your radio. Fasten the screw by turning it clockwise.

4. Press and hold the orange pairing button for 6 seconds. You will hear another tone and the LED will alternate flash blue and red. This means it’s now in pairing mode.

5. On your radio, press and hold the pairing button on the adapter and turn on your radio simultaneously. Continue holding the pairing button for five seconds after the radio has been turned on. The light should now be flashing blue twice per second. The adapter is now in pairing mode.
6. Do not touch the pairing button until it turns to one continuous LED light for 3 seconds and the speaker microphone flashes blue every 2 seconds.
7. After a few seconds, you should hear a tone on your speaker microphone. Both devices are connected and ready to use. The devices should now automatically pair when both are turned on.
Note: The BTH-500 can only be paired to one radio. When you pair it to a new radio the old one will be erased.
