Only insert batteries of the same type and always
replace all batteries.

If the unit is not used for a longer period (e. g. more
than a week), remove the batteries. Thus, the unit
will not be damaged in case of battery leakage.
1) Open the Velcro fastener and take the transmitter
out of the belt bag.
2) Remove the cover (11) of the battery compartment.
Then the battery compartment (10) will be acces -
sible.
3) Insert two 1.5 V batteries of size AA (R6) with the
positive and negative connections as indicated in
the compartment.
4) Replace the cover.
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 power
switch (2) to position ON. The display will indicate
the transmission group adjusted with the corre-
sponding transmission channel (3) and a battery
symbol (7) showing the current charging status of
the batteries in several steps:
fully charged
4) Set the transmitter to the same transmission group
and the same transmission channel adjusted on the
receiver → chapter 5.1.
5) Speak/sing into the microphone connected. The
volume level can be readjusted by changing the
sensitivity via the trimming control GAIN (9) 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 of 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.
6) The transmitter can be locked to prevent accidental
change of the transmission channel or switching off
→ chapter 5.2.
7) After all adjustments have been made, put the
transmitter back into the belt bag and secure it
