Establishing A Transmission Path - IMG STAGE LINE TXS-900 Bedienungsanleitung

2) Keep the button SET pressed for approx . 1 sec-
ond until the channel indication (E) and the
frequency indication (G) start flashing . The
group setting mode has been activated: The
corresponding indication "P1" ... "P4" (B) starts
flashing . Use the button
group .
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 .
3) 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 signals
from another wireless system are received . In
this case, use a different transmission channel .
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 keep-
ing 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
synchronizing, make sure that the maximum
distance of 1 m between the receiver and the
transmitter is not exceeded .
3) When the receiver and the transmitter have been
set to the same transmission channel, the bar-
graph 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 reception

or poor reception, please check the following
items:
a) Are the batteries of the transmitter dis-
charged?
b) Are there any metal objects or other high-
frequency sources interfering with the recep-
tion?
c) Is it possible to improve the reception quality
by turning the receiving antennas?
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 trans-
mitter . 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 (
TXS-900HSE) .
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 insufficient: 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 interference resistance, but it will also reduce
the transmission 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 .
