3. Adding Friends and Group Management

The Odmaster App allows for comprehensive management of your contacts and groups.

Adding Friends:

Scan to add friends: Click the "Scan" button in the app, then scan your friend's user QR code. The user will appear in your friend list after successful addition. (Note: Only Odmaster QR codes are supported.)
Search ID/nickname to add friends: Click the "Add Friends" button, enter the ID or nickname in the input box, and search to add.

Creating/Joining Groups:

Note: The APP is primarily for group management (add/delete/modify/view groups). Joining a group in the app does not automatically place the radio in that group; switching groups still requires operation on the radio itself.

Troubleshooting

If you encounter any issues with your TD-M15 radio, refer to the following common problems and solutions. If the issue persists, please contact support.

1. Poor Signal Received

Possible reasons: The network signal at your current location is weak (e.g., in a basement or near a large building), radio waves are difficult to transmit effectively, or the network is busy (e.g., high network traffic during peak hours).

Solutions:

Move to a location with better network coverage.
Avoid using it during peak network times, or wait a moment and try again.

2. Echo or Noise

Possible reason: Poor network relay lines from some network operators.

Solution: Turn the radio off and then restart it. It will automatically search for base stations and switch to a network with better quality.

3. Shortened Standby Time

Possible reasons:

Standby time can vary based on the system settings of the network operator.
The battery may be running down, especially if used in high-temperature environments.
If the radio cannot connect to the network, it continuously emits signals to search for base stations, which consumes battery power rapidly.

Solution: If you are in an area with a weak signal, temporarily turn off your radio to conserve battery.
