Compatibility with MXP600 and R7:
The WM500 is compatible with MXP600 and R7 radios from v4.0.0 (or R04.00.00) firmware onwards. If the WM500 is running an older firmware version, it must be upgraded using the Accessory Manager application to ensure full compatibility and functionality with these radios.
Connecting to WAVE and Nitro Devices:
- Bluetooth Accessory Configuration in Wave Portal:
- Select the desired WAVE or SLN1000 device in the Wave On Cloud portal.
- Go to "Actions" > "Bluetooth Accessories."

Troubleshooting (FAQ):
- Changing Voice Announcement Language: Upgrade Accessory Manager app to V1.0.11+, upgrade WM500 software to R04.00.00 via the app, then update language options.
- Accessory Manager on Apple App Store: Currently in development, expected Q1-2022.
- Reconnection Issues with R7 Radio: If "Connecting Failed" is displayed, Bluetooth LED is solid blue, a "bad bonk" audio is heard, and "Disconnected" notification occurs, the recovery method is to power off the WM500, power cycle the R7 radio, clear WM500 pairing info from the R7, and perform a fresh pairing.
