Operation
To switch the Pilot Tone ON/OFF
The pilot tone is switched off by activating both keys (+) and (-) simultaneously twice.
Then the pilot LED is switched off indicating that the pilot has been switched off.
In order to switch on the pilot tone both keys (+) and (-) are pressed simultaneously
only once. Thus the pilot LED flashes and the level can be changed. If the level is
correct, the LED will flash quickly after 5 seconds and the current set-up is stored in
the memory.
