Pocket Transmitter - Monacor International JTS PT-850B/1 Mode D'emploi

5 Setting the Transmitter
into Operation
1) Connect the Lavalier microphone CM-501 sup-
plied to the mini XLR jack INPUT (3) and fasten
it to your clothes (e g tie or lapel) by means
of the clip
It is also possible to use another matching
JTS microphone with 4-pole mini XLR plug
2) Before switching on the transmitter, set the
receiver to an interference-free transmission
channel (see instruction manual of the receiver)
3) Then switch on the transmitter: Set the sliding
switch (2) to ON The LED status indication (4)
lights up in green to indicate normal operation
If it lights up in red after switching on or during
operation, the inserted batteries are almost dis-
charged and must be replaced
4) Set the transmitter to the same channel ad-
justed on the receiver: For this purpose, turn
the rotary switch CH (5) by means of the small
adjusting key supplied in such a way that the
arrow will point to the desired channel
The 16 transmission channels are assigned
to the following transmission frequencies:
Channel Frequency
1 863�125 MHz
2 863�250 MHz
3 863�375 MHz
4 863�500 MHz
5 863�625 MHz
6 863�750 MHz
7 863�875 MHz
8 864�000 MHz
Note: If other wireless transmission systems are
operated with this wireless system at the same
time, the radio frequencies of the individual sys-
tems should be carefully matched to each other to
prevent interference
5) Speak / sing into the microphone The volume
level can be readjusted by changing the sen-
sitivity via the gain control (6) For turning the
control, use the adjusting key supplied Adjust
the transmitter to the optimum level If the level
is too high, the transmitter will distort; in this
case, turn back the control (if necessary, turn
it to the left stop) If the level is too low, a
