Infra-red disable
You can protect the miniTX from an accidental change

the infra-red port on the transmitter. This will prevent all

Sleep mode
The miniTX can be put into sleep mode using the SwitchiR.
In sleep mode the orange LED will flash every two seconds.
The miniTX uses very little current and the SwitchiR can still
be used to read all settings other than frequency.
When not in use the power should be switched off by
removing the microphone plug or input cable.
