5. Operation
1) To switch on the units of the system, press
the button POWER (3). The POWER LED (4) will
show green. If it shows red, the battery is almost
discharged and should be recharged as soon as
possible. Whenever a button is pressed, the dis-
play (6) will indicate the transmission channel
adjusted for approx. 9 seconds, then the chan-
nel number will disappear. To reactivate the dis-
play for approx. 9 seconds, shortly press a
button on the unit.
2) Select a transmission channel from the 16
channels available ( frequency list attached). Al-
ways set the transmitter and the receiver /
receivers of a system to the same channel. To
set the channel, keep the button CHANNEL (7)
pressed until a LED starts flashing on the display
next to the channel number. Then press the
button CHANNEL repeatedly until the desired
channel is indicated. When the LED on the dis-
play disappears approx. 6 seconds after the last
actuation of the button CHANNEL, the channel
selected has been memorized.
3) Speak into the internal microphone (9) of the
transmitter or into the earband microphone
connected.
4) If the reception is bad, check if:

Transmission is better on another channel.

Distance between the transmitter and the
receiver is too large.

There are obstacles between the devices
that can disrupt the radio signal.
5) To reset a device in case of malfunctions, acti-
vate the RESET key (2) with a thin object, for
example a metal pin. The device turns off and
can be turned on again.
6) To switch off, press and hold the POWER
button until the operation LED goes out.
