5 Operation

1) Do not switch on the transmitter of the system
yet; switch on the receiver first: Set the on /off
switch (8) to ON . When the unit is switched
on, the ring around the REMOSET button (3)
lights up . After briefly indicating the identifi-
cation number (

☞
– the indication MUTE (f)
The muting function will be activated when
no radio signal is received from the transmit-
ter on the transmission frequency adjusted,
when the signal received is poor or when the
transmitter is muted (possible for transmitter
TXS-865HT only) .
2) Before switching on the transmitter, set the
receiver to a free and interference-free trans-
mission frequency
transmission frequency has been set and the
reception indication RF (a) shows a radio signal
(one or several segments of the indication are
displayed), select a different frequency .
3) Switch on the transmitter, check its settings
( ☞ instruction manual of the transmitter), then
set it to the same transmission frequency via the
REMOSET function according to chapter 5 .2 .
When the transmitter and the receiver have
been set to the same frequency, the muting
function is deactivated; the indication MUTE (f)
disappears . One of the indications
is displayed to show which of the antennas (1)
receives the more powerful radio signal . The
indication RF (a) shows the reception quality:
the more segments displayed, the better the
reception .
If the reception is poor, please check:
– if the batteries of the transmitter are exhausted .
The display shows a battery symbol (d) indi-
cating the status of the batteries in the trans-
mitter in four levels .
– if the transmission power of the transmitter
is too low .
To increase the transmission range when the
transmitter is placed at a greater distance
from the receiver, it is possible to increase the
transmission power from 10 mW to 50 mW
(possible for transmitter TXS-865HT only,
instruction manual of the transmitter) .

transmission path .
Make sure to keep the transmitter and the
receiver at a minimum distance of 50 cm from
metal objects and any other sources of inter-
ference, e . g . electric motors or fluorescent
lamps .
– if the reception is improved when you move
the antennas .
– if the squelch threshold adjusted with the
SQUELCH control is too high
4) Speak / sing into the microphone of the transmit-
ter or, when picking up the sound of an instru-
ment, feed an audio signal to the microphone .
The indication AF (b) shows the volume level of
the audio signal received . The more segments of
the indication AF displayed, the higher the level .
Set the transmitter to the optimum volume
via the indication AF
the transmitter .
5) Use the volume control (2) to match the output
level of the receiver to the input of the subse-
quent unit . If you use the XLR audio output and
the level is too high even when the volume is
low, attenuate the level by 20 dB with the toggle
switch ATTENUATION (10) .
6) Use the control SQUELCH (12) to adjust the
threshold for interference suppression . The fur-
ther the control turned clockwise, the higher
the threshold .
Interference suppression will mute the re-
ceiver when high-frequency interference signals
(c)
B
with a level below the threshold adjusted are
received during music intervals . With a higher
threshold, however, the transmission range
will decrease as the receiver will also be muted
when the signal strength of the transmitter falls
below the threshold adjusted . Therefore, adjust
a higher threshold with the control SQUELCH
when the reception is good; select a lower value
when the transmitter is placed at a greater dis-
tance from the receiver .
7) The receiver is provided with a lock function to
prevent accidental change of settings or switch-
ing off
☞
8) After operation, set the on /off switch (8) to OFF .
If the receiver is not in use for a longer period of
time, disconnect the power supply unit from the
mains socket; even when the receiver is switched
off, the power supply unit will have a low power
consumption .
