( ☞ chapter 7, step 2), they will be transferred to
the transmitter . However, it is also possible to set
the transmission power and the gain on the trans-
mitter itself .
1) The transmission power is adjustable in three
levels . When the transmission power is reduced,
the power consumption will also be reduced .
Thus, the battery life will be longer, but the
transmission range will be shorter . Use the but-
ton SET to select the function "setting of trans-
mission power" (indication
and the button
displayed = highest transmission power) .
2) The gain setting can be used to reduce the mi-
crophone sensitivity (for wireless microphone
TXS-1800HT) or the sensitivity of the microphone
input (for pocket transmitter TXS-1800HSE) and
thus to readjust the volume level of the trans-
mitter . Use the button SET to select the function

used will be skipped during the channel scan .
Unlock the buttons (

channel indication will keep rotating . To stop the
scan, press the button AUTO once again . At the
end of the scan, the radio frequency found and the
corresponding channel number will be indicated

7 Establishing a Transmission Path

1) Set the radio frequency on the receiver (
ter 6 .2 .1, chapter 6 .3) . Do not switch on the
corresponding transmitter yet . If the transmitter
is still switched off and the bargraph RF on the
display (4) indicates a signal, interference or sig-
nals from another wireless system are received .
In this case, use a different radio frequency .
2) Switch on the transmitter and open its battery
compartment so that the IR sensor is not
covered . Aim the IR sensor at the IR transmit-
ting diode (2) of the receiver . Make sure that
there are no obstacles between the IR sensor
and the IR transmitting diode (distance up to
approx . 2 m) .
For frequency synchronization, press the
button ADL (3): The transmitter will be matched
to the radio frequency of the receiver by IR sig-
nal . The transmission power and the gain set-
☞
ting ( chapter 6 .2 .3) will also be transferred
to the transmitter . During IR transmission, the
wave symbol in the indication
To indicate successful transmission, the display
of the transmitter will light up for a few seconds .
Note: The radio frequency, transmission power and
gain can also be set manually on the transmitter .
3) When the receiver and the transmitter have
been set to the same radio frequency, an
antenna symbol

of the receiver (depending on which of the two
separate receiver sections of the unit receives
the radio signal of the highest quality at this
moment) and the bargraph RF will indicate that
will
a radio signal is being received .
In case of no reception or poor reception, please
check the following items:
a) Are the batteries of the transmitter dis-
charged?
Both on the display of the receiver and on the
display of the transmitter, a battery symbol
indicates the battery status .
b) Are there any metal objects or other high-
frequency sources interfering with reception?
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 range depends on local conditions
(up to approx . 100 m in the open) . The trans-
mission path should be free of any obstacles .
e) Is the squelch too high and / or the trans mission
power too low? (
