Hi Keith Evans 3,
I have just seen this thread. Do you sill have an issue with the 14SG? If so...
I suggest storing the 14SG in a warm dry place for a few days then see if the problem persists.
To access "power mode" (for performing range checks etc..) press RTN and switch on.. If the transmitter continues to access "power mode" unexpectedly I would suspect the RTN button is faulty and suggest having it replaced.
I hope this helps.
Nick
