2 Safety Notes
The units (receiver and power supply unit) corre-
spond to all relevant directives of the EU and are
therefore marked with
.
WARNING The power supply unit uses dan-
gerous mains voltage. Leave ser -
vicing to skilled personnel only.
Inexpert handling may result in
electric shock.
Please observe the following items in any case:
G
The units are suitable for indoor use only. Pro-
tect them against dripping water and splash
water, high air humidity and heat (admissible
ambient temperature range: 0 – 40 °C).
G
Do not operate the receiver and immediately
disconnect the power supply unit from the
mains socket
1. if the receiver or the power supply unit is
visibly damaged,
2. if a defect might have occurred after a unit
was dropped or suffered a similar accident,
3. if malfunctions occur.
In any case the units must be repaired by
skilled personnel.
G
For cleaning only use a dry, soft cloth; never
use water or chemicals.
G
No guarantee claims for the units and no lia-
bility for any resulting personal damage or
material damage will be accepted if the units
are used for other purposes than originally
intended, if they are not correctly connected or
operated, or if they are not repaired in an
expert way.
If the units are to be put out of operation
definitively, take them to a local recy-
cling plant for a disposal which is not
harmful to the environment.
3 Applications
Combined with two transmitters of the TXS-900
series from "img Stage Line" (wireless micro-
phone TXS-900HT or pocket transmitter TXS-
900HSE with a microphone connected), the
2-channel multi-frequency receiver TXS-920 can
be used to set up two wireless audio transmis-
sion systems, e. g. for stage applications. The
receiver uses "True Diversity" technology and
operates in the two UHF ranges 823 – 832 MHz
and 863 – 865 MHz.
The two identical sections of the receiver are
operated separately. For each receiver section,
there are 3 operating modes to set the transmis-
sion channel: manual setting, channel scan or
selection from one of 4 preset groups (8 chan-
nels in each group). The receiver section and the
transmitter are synchronized by radio transmis-
sion: When the synchronization button is kept
pressed on the transmitter and the button SYNC
is briefly pressed on the receiver section at the
same time, the transmitter is set to the transmis-
sion channel of the receiver section.
3.1 Conformity and approval
Herewith, MONACOR INTERNATIONAL de clare
that the receiver TXS-920 is in accordance with
the basic requirements and the other relevant
regulations of the directive 1999 / 5/ EC. The dec-
laration of conformity is available on request from
MONACOR INTERNATIONAL. The re ceiver is
generally approved for operation in EU and
EFTA countries; it is licence-free and requires
no registration.
