compartment (11) on the rear side will be accessi-
ble (see fig. 3).
2) Insert two 1.5 V batteries of size AA (R6) with the
positive and negative connections as indicated in
the compartment.
3) Unlock the control part again, slide it back to its pre-
vious position and let it lock into place.
5 Setting the Transmitter into Operation
1) Connect the Lavalier microphone CM-501 supplied
to the mini XLR jack INPUT (4) 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 (see chap-
ter 3).
2) Before switching on the pocket transmitter, set the
receiver to an interference-free transmission chan-
nel (see instruction manual of the receiver).
3) Then switch on the transmitter: Slide the switch (2)
to the position ON. The display (3) will indicate the
transmission group adjusted with the corresponding
transmission channel (in the group mode), e. g.
or the transmission frequency (in the frequency
mode) and a battery symbol showing the current
charging status of the batteries in several steps:
fully charged
If the batteries are exhausted (indication
colour of the display on the receiver will additionally
change from green to orange as a warning.
4) Press the locking buttons (8) on the sides of the
transmitter and slide the control part upwards in its
casing until it locks into place (see fig. 1).
5) Set the transmitter to the same transmission
group and the same transmission channel or the
same radio frequency adjusted on the receiver:
→ chapter 5.1 or chapter 5.2.
6) Speak/sing into the microphone connected. The
volume level can be readjusted by changing the
sensitivity via the trimming control GAIN (10) on the
rear side of the control part (fig. 2). For this pur-
pose, use the adjusting key supplied. Adjust the
transmitter to the optimum level according to the
indication AF on the display on the receiver. 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 poor signal-
noise ratio will result; in this case, advance the con-
trol correspondingly.
7) The transmitter can be locked to prevent accidental
change of the radio frequency or switching off
→ chapter 5.3.
8) After all adjustments have been made, unlock the
control part, slide it back to its previous position and
let it lock into place. Fasten the transmitter to your
clothes (e. g. belt or waistband) by means of the
clip (9).
To modify the position of the transmitter on your
clothes, the clip can also be mounted in a different

decreased by 25 kHz; each time the key
pressed, it will be increased by 25 kHz. To scan a
wide frequency range, keep the corresponding key
pressed.
Note: If several wireless transmission systems are
operated at the same time, the radio frequencies
of the individual systems should be carefully
matched to each other to prevent interference.
Examples for frequencies for simultaneous op -
eration of several systems can be found in the
