8. FAQ – Common Issues

The LED stays blue, my device does not connect.

Check that the Master (M) device is in pairing mode, bring the devices closer together, and repeat the connection procedure.

I hear nothing in the earpiece.

Check the earpiece volume, make sure the mute function is not activated, and that the devices are paired (green light).

Multiple groups use WHIS® systems simultaneously.

Change the channel on the Competition devices and make sure all devices in the same group are set to the same channel.
