6 OPERATION
6.1 Switching on
■
Keep the ON/OFF button pressed for 2 seconds to switch on the microphone.
The power indicator lights red. The display indicates O
adjusted and the battery status. The display goes off if no button is pressed
within 5 seconds. It can be switched on again by pressing any button.
6.2 Frequency adjustment
■
To select a transmission channel keep the SET button pressed until the channel indication starts flashing.
It keeps flashing for approx. 10 seconds. During that time, the channel can be adjusted with buttons ▲ and
▼. Press the SET button to confirm the channel selection (within 10 seconds) otherwise the microphone
returns to the channel previously adjusted.
■
The display can indicate the radio frequency for the adjusted channel. As long as one of the buttons ▲ and
▼ is pressed, the display indicates the frequency instead of the channel. (Please refer to chapter 7.1
Channel configuration for a table listing which channel is assigned to which frequency).
6.3 Sensitivity
■
The sensitivity of the microphone can be adjusted in two steps with the SENSITIVITY switch (upper
position: high sensitivity, central position: low sensitivity). Thus, the volume level of the microphone can
be readjusted. Reduce the sensitivity if the volume of the microphone signal is too high and thus
distorted. Increase the sensitivity if the volume is too low and a poor S/N ratio results.
6.4 Muting
■
To mute the microphone during operation, set the MUTE switch to its lower position. Then, no sound
will be transmitted.
6.5 Switching off
■
To switch off the microphone, keep the ON/OFF button pressed for approx. 2
seconds until the display indicates OFF.
■
If the display indicates Err (Error) when switching off, press buttons SET, ▲
and ▼ simultaneously to switch off the microphone. If the microphone is switched off
automatically after a short time, keep buttons ON/OFF, SET ▲ and ▼ pressed simultaneously, until the
display indicates O
. Then, normal operation is possible again. If it is not possible to eliminate the fault by

these measures of if other malfunctions occur, remove the batteries and reinsert them.
