system: If the power of the radio signal falls
below the threshold value adjusted, the receiver
is also muted . Therefore, adjust a high threshold
value (turn the control towards MAX) when the
reception is good and a low value (turn the con-
trol towards MIN) when the distance between
the transmitter and the receiver is long .
8) The wireless microphone has a lock feature . To
activate the lock, set the switch LOCK (18) in
the battery compartment to the position ON .
The displays shows a key symbol and it is not
possible to switch off the microphone with the
switch (16) or to set it to a different channel via
IR signal . However, it is still possible to mute the
microphone when you set the switch (16) to the
mid-position or the lower position .
9) After operation, switch off the units with the
corresponding switch (9, 16, 21) . If the micro-
phone system is not in use for a longer period
of time, disconnect the power supply unit of
the receiver from the mains socket; even with
the receiver switched off, it has a low power
consumption .
