Things to try when a radio system has crackling, poor connection, low volume or no connection, troubleshooting OPUS 2, Nucleus 6 and 7, and Sonnet audio processors.
Troubleshooting radio systems
A radio system consists of:
- a transmitter (Tx), worn by the person speaking
- a receiver (Rx), worn by the listener
If there's crackling, poor connection, low volume or no connection in a radio system, try the following:
- fully unwind the external aerial for good signal
- position microphone a pen's length from the mouth, in a central position
- connect the Tx to the Rx when on the hearing device by pressing the connect button on the Tx within 10cms of Rx
- repeat this process for best signal
- check the battery of the Tx is charged
- check the batteries of the hearing device are not flat, give the Rx power
- check all devices are switched on: the switch for the MicroMlxs must be on the two full dots setting
- check paperwork from Sensory Support Service: for FM use, the number in the Tx screen must match the FM channel programmed in the Rx
- check with the Teacher Of the Deaf that the Rx is on the correct setting for the device of children with cochlear implants
- check the gold pins on the Rx are clean: they can be affected by debris and condensation and may look green at the base
- try the system in different parts of the room or building for persistent interference: interference may be caused by metalwork, obstructions in rooms and other equipment
- try system reset by holding down all 4 corner buttons on the Tx: release and the system will reboot
For more advice, contact:
- the Teacher of the Deaf supporting the setting
- the Audiology Technician
