2.4 Turning the instrument on
When the instrument turn on button (pos.5 figure 2.2) is
depressed the power supply of the receiver is turned on.
The receiver conducts a short test
of the LED, plays the welcome music (if the sound is on)
and outputs the battery voltage in volts (for instance,
voltage of 3,0 V at figure 2.2).
The indication of battery voltage is kept on the screen for
about 2 sec, then the current operating frequency is
displayed (for instance frequency of 8928 Hz figure 2.3): If
batteries voltage is lower than 2,6 V (2,2 V for
accumulators), batteries require to replacing (ref. to p.
2.11).
After that the receiver comes to the search mode of
maximum at the frequency at which the receiver has been used in the previous session with
switched off mode "SuperMax" and auto set amplification.
2.5 Operation frequency selection
The first depression on the operation frequency selection button pos.8 figure 2.1 displays the
current working frequency, following ones
– scan through the operation frequencies. In doing
this the first offered frequency is the one used before (for more comfortable switching between
the passive mode and used generator frequency), then the next frequencies are offered from low
to high. The basic version of the receiver supports eight operation frequencies:
