channel number, keep the button SELECT(2)
pressed until the units digit on the display (3)
starts flashing. Press the button briefly to adjust
the units digit. Keep the button pressed again
until the tens digit on the display starts flash-
ing. Press the button briefly to adjust the tens
digit. A few seconds after you have pressed the
button for the last time, the the digit will stop
flashing to indicate that the channel adjustment
has been stored.
4)
Point the IR sensor (15, 23) of the wireless
microphone / pocket transmitter towards the IR
window (6) on the receiver. The distance must
not exceed 1.5 m. Make sure that there are
no obstacles between the sensor and the IR
window.
Keep the button ACT (7) pressed for a few
seconds until the display backlight of the wire-
less microphone or the pocket transmitter has
been activated. Thus, the wireless microphone
or the pocket transmitter and the receiver have
been set to the same channel. The display (14
or 22) shows the channel number.
5 Operation
1)
Put the receiving antennas (1) in a vertical
position.
2) Switch on the receiver with the POWER switch
(9) first. The LED AF (4) flashes twice. The display
(3) shows the transmission channel adjusted.
If one of the reception LEDs RF (5) lights up
while the wireless microphone
1
or the pocket
transmitter
2
is still switched off, interfering sig-
nals or signals from another wireless system are
received. In this case, adjust a different channel
(
☞
chapter 4.4).
3)
To switch on the pocket transmitter, set the
switch (21) to the position ON. To switch on the
wireless microphone, set the switch (16) to the
upper position. For transmitting sound, set the
switch on the wireless microphone to the upper
stop or set the switch on the pocket transmitter
to ON. In the mid-position, the transmitter is on,
but the microphone signal is muted.
After switching on, the backlight of the
display (14, 22) lights up for a few seconds.
The display shows the channel adjusted and
the battery status.
full discharged
Note: Replace the batteries when the indication BATT
starts flashing.
4) On the wireless microphone, adjust the trans-
mitting power with the switch POWER (19) in
the battery compartment.
– upper position HI = high power for a long
range, but reduced battery life
– lower position LO = low power for a long life,
but reduced range
5) When the transmitter (wireless microphone or
pocket transmitter) is switched on, one of the
reception LEDs RF A or B (5) lights up on the
receiver to indicate which receiving part sup-
plies the best signal. If none of them lights up,
please check:
a Have the transmitter and the receiver been
set to the same channel?
If different channels are indicated on the
receiver and on the wireless microphone /
pocket transmitter, proceed with step 4 of
chapter 4.4.
b
Are the batteries of the transmitter dis-
charged?
c
Has the wireless microphone been set to a
low transmitting power?
d Is the distance between the transmitter and
the receiver too long?
Range:
TXS-611 / -631 / -636SET : approx. 30 m
TXS-616SET : approx. 50 m
e
Is the reception disturbed by metal objects in
the transmission path?
f Is it possible to improve the reception when
you turn the receiving antennas (1)?
g
Has the interference suppression been set too
high with the control SQUELCH (13)?

step 7)
6) Switch on the following audio unit or advance
the corresponding mixer control. Speak/sing
into the microphone and match the output level
of the receiver to the input of the following unit
with the control VOLUME (12).
On the pocket transmitter, adjust the gain
for the microphone connected with the control
GAIN (27) on the rear side: If the volume of the
microphone signal is too high and the signal is
distorted, turn back the control with a small
screwdriver. If the volume of the signal is too
low, however, the signal-to-noise ratio is poor;
advance the control accordingly.
7)
With the control SQUELCH (13), adjust the
threshold value for response of the interfer-
ence suppression. The interference suppression
will mute the receiver during pauses in speech
