2) Keep the button SET pressed for approx. 1 sec-
GB
ond until the channel indication (E) and the fre-
quency indication (G) start flashing. The group
setting mode has been activated: The corre-
sponding indication "P1" ... "P4" (B) starts flash-
ing. Use the button
Then press the button SET to go to the chan-
nel setting mode. In the channel setting mode,
the corresponding channel number "1" ... "8"
(C) starts flashing. Use the button
select the channel within the group selected.
Note: When no button is pressed in the group setting
mode, the receiver will go to the channel setting mode
after a few seconds. When no button is pressed in the
channel setting mode, the mode will be exited after a
few seconds.
4) The channel setting mode will be exited auto-
matically after a few seconds or when the button
SET is pressed.

8 Establishing a Transmission Path

1) Set the transmission channel on the receiver
( chapter 7). Do not switch on the correspond -
ing transmitter yet. If the bargraph RF (H) on the
display indicates a signal, interference or sig-
nals from another wireless system are received.
In this case, use a different transmission chan-
nel.
2) Set the receiver and the transmitter to the same
transmission channel: To synchronize the
receiver and the transmitter, first keep the
blue synchronization button pressed on the
transmitter: "SYNC" (D) starts flashing on the
display of the receiver. Then, while still keeping
the synchronization button pressed on the
transmitter, briefly press the button SYNC (3) on
the receiver. Thus, the transmitter is set to the
transmission channel of the receiver. When syn-
chronizing, make sure that the maximum dis-
tance of 1 m between the receiver and the trans-
mitter is not exceeded.
3) When the receiver and the transmitter have
been set to the same transmission channel, the
bargraph RF on the display will indicate the
strength of the radio signal received.
Take the transmitter and walk around the
area where it is operated. In case of no recep-

or
tion or poor reception, please check the follow-
ing items:
a) Are the batteries of the transmitter dis-
charged?
b) Are there any metal objects or other high-fre-
quency sources interfering with the recep-
tion?
c) Is it possible to improve the reception quality
by turning the receiving antennas?
to
d) Are the receiver and the transmitter too far
apart? The transmission range depends on
local conditions (up to approx. 100 m in the
open). The transmission path should be free
of any obstacles.
e) Is the squelch too high (
4) Switch on the subsequent audio unit or raise the
corresponding control of the mixer and speak /
sing into the microphone of the transmitter. The
bargraph AF (I) on the display of the receiver
indicates the volume level of the transmitter. For
the pocket transmitter, use the gain switch to
adjust the level (
Use the volume control (6) to adjust the out-
put level of the receiver.
8.1 Squelch
To adjust the squelch threshold, use the control SQ
(10). The squelch function will mute the receiver
when the level of the radio signal received falls
below the threshold value adjusted. Thus, interfer-
ence signals will not cause any noise at the
receiver when the transmitter is switched off or
when the radio signal of the transmitter is insuffi-
cient: If the levels of the interference signals are
below the threshold value, the receiver will be
muted.
Use the control SQ to adjust the threshold value
so that there will not be any noise at the receiver
when the transmitter is switched off. The more the
control is turned clockwise, the higher the threshold
value. A high threshold value will offer high interfer-
ence resistance, but it will also reduce the trans-
mission range of the wireless system since, during
operation, the strength of the transmitter signal
must be high enough to prevent muting of the
receiver. Thus, when the reception is good, a high
threshold value can be used; however, when the
transmitter and the receiver are far apart, a low
threshold value is recommended.
