Power Supply; Setting Into Operation - JTS MH-8800G Instruction Manual

4 Power Supply

G
Only insert batteries of the same type and always
replace all batteries.
G
If the microphone is not used for a longer period
(e. g. more than a week), remove the batteries.
Thus, the microphone will not be damaged in case
of battery leakage.
1) Unscrew the cap (7) for the battery compartment.
2) Insert two 1.5 V batteries of size AA (R6) with the
positive and negative connections as indicated on
the holder.
3) Place the battery compartment cap straight against
the thread of the microphone body and screw it on.

5 Setting into Operation

1) Before switching on the microphone, set the re -
ceiver to an interference-free transmission channel,
see instruction manual of the receiver.
2) Then switch on the microphone: Set the POWER
switch (9) at the lower end of the microphone to
position POWER. If required, slide the safety cap
(10) downwards beforehand. The display will indi-
cate the transmission group adjusted with the cor-
responding transmission channel (3) and a battery
symbol (2) showing the current charging status of
the batteries in several steps:
fully charged
3) The keys (4 – 6) which are slightly recessed can
easily be actuated by means of the tip of your
thumb without any further aid.
4) Set the microphone to the same transmission
group and the same transmission channel adjusted
on the receiver → chapter 5.1.
5) Speak/sing into the microphone. The mute switch
(11) must be in the position OFF, otherwise no
audio signal will be transmitted. The volume level of
the microphone can be readjusted by modification
of the sensitivity → chapter 5.2.
6) The microphone can be locked to prevent acciden-
tal modification of the adjustments or switching off
→ chapter 5.3.
7) For short interruptions, the signal transmission can
be muted → chapter 5.4.
8) The identification ring (8) can also be exchanged
against one of the coloured rings supplied. This
allows colour coding of several systems with dif -
ferent radio frequencies.
9) To switch off the microphone after operation, set the
POWER switch (9) to OFF.

until the display shows
will then return to normal operation.
2) Use the cursor keys to adjust the transmission
group: With the key
in descending order, with the key
order. The corresponding channels and transmis-
sion frequencies can be found in the table fig. 4.
Note: If other 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
Internet on www.jts-germany.de under "Informa-
tionen/Intermodulationsfreies Frequenzsetup".
3) Press the key SET again to recall the channel ad -
justing mode. On the display, the channel indication
1 – 16 starts flashing.
4) Use the cursor keys to adjust the transmission
channel: With the key
