Battery compartment SR-LR switch
The SR-LR switch changes the transmitter range.
Factory setting LEFT= ‘SR’.
SR is Standard Range, indicated by three bars on the aerial display.
LR is Long Range, indicated by four bars on the aerial display.
You will probably only select LR (Long Range) when using cochlear
implant processors or Phonak MicroMLxS receivers to increase range or
reduce occasional interference problems. It will also give a longer range in
outdoor pursuits.
Battery compartment TH control
The TH control adjusts the threshold level for showing the sound
present symbol on the status display.
Factory setting ‘5 o’clock’ (fully CW).
You will only need to adjust this control if you find that the auto power-off
does not operate due to a high level of general background noise.
Fully clockwise is the most sensitive.
The fmGenie has an auto power-off facility – if no sound passes through
the system for an hour the fmGenie will turn itself off to save wasting
batteries. The TH control sets the sound detection threshold for the sound
present symbol which resets the ‘auto power-off’ timer when it flashes.
