Instruction manual

6 Operation
1) To switch on the units, press the button #
POWER (3). The power LED (4) shows green. If
it shows red, the battery is almost discharged
and should be recharged as soon as possible.
The display (7) indicates the transmission
channel adjusted for a few seconds. Then it is
extinguished. To illuminate the display for a few
seconds, press the button POWER or CHAN-
NEL (8).
2) Select a transmission channel from the chan-
nels available (0 to F, see table below). Set the
transmitter and the receiver to the same chan-
nel: Keep the button CHANNEL (8) pressed
until a dot starts flashing on the display. Then
press the button CHANNEL repeatedly until the
desired channel is indicated. The channel
selected has been stored when the dot on the
display disappears (approx. 6 seconds after the
last actuation of the button CHANNEL).
3) Adjust the volume for the audio signal transmit-
ted with the control GAIN (6) on the transmitter.
For this purpose, use the adjusting key (10). If
the volume is too high, the signal will distort; in
this case, turn the control counterclockwise. If
the volume is too low, there will be a poor signal-
to-noise ratio; in this case, turn the control clock-
wise.
4) On the receiver, use the rotary switch PAD (6) to
match the output level of the jack AF OUT (1) to
the unit connected. For this purpose, use the
adjusting key (10). The switch has 3 levels:
0 dB,
- 10 dB and - 20 dB.
5) If the reception is poor or disturbed, please
check
– if the transmission is better when a different
channel is used.
– if the transmitter and the receiver are too far
apart.
– if there are obstacles in the transmission
path which may shield the radio signal.
6) To reset a unit in case of malfunction, press the
button RESET (2) by means of a thin object,
e. g. a metal pin. The unit is switched off and can
be set into operation again.
7) To switch off the units, keep the button
POWER pressed until the power LED is extin-
guished.
