Trantec S3500 beltpack fault

[richardash1981]

I have a Trantec S3500 radio mic beltpack which has developed an odd fault. If it is kept cool all is well.If it is warmed up towards body temperature (as tends to happen if worn on the belt clip ...) then it starts glitching every 3 seconds. The display goes from normalTrantec_S3500_normal on Flickrto this:Trantec_S3500_glitch , on Flickrfor a fraction of a second (not long enough to read it!).

At the same time the audio cuts out, and you get the "chiff" from the receiver muting circuit operating.

Video of the display (no audio) here:

Anyone know what the display information means?
