Setting Into Operation; Locking/Unlocking The Unit - Monacor International JTS PT-920B Manual De Instrucciones

5 Setting into Operation

1) Connect the supplied Lavalier microphone CM-501
to the 4-pole mini XLR jack INPUT (4) and fix it with
the clip to your clothes (e. g. tie or lapel).
Instead of the Lavalier microphone it is also pos-
sible to use a matching headband microphone or
instrument microphone (e. g. CM-204..., CX-504,
CX-508W, or CX-516W from JTS).
2) To switch on, set the power switch (2) to ON. The
display (3) indicates the transmission channel ad-
justed and a battery symbol which indicates the
current charging status of the batteries in several
steps:
fully charged
3) Adjust the transmission channel for the transmitter
→ see chapter 5.1. Switch on the receiver and
adjust it to the same channel → see instruction
manual of the receiver.
Switch on the audio unit (mixer or amplifier)
connected to the receiver.
4) Speak/sing into the microphone. The volume level
can be readjusted by changing the sensitivity via
the control GAIN (8). Use the supplied adjusting
key for turning the control.
Adjust the transmitter to an optimum level. If the
level is too high, the transmitter will distort, in this
case turn back the control (if required, even to the
left stop). If the level is too low, a poor signal-noise
ratio will result, in this case, advance the control
correspondingly.
5) The transmitter may be locked to prevent acciden-
tal change of of the transmission channel or acci-
dental switching off → chapter 5.2.
6) After all adjustments have been made, put the
transmitter back into the belt bag and secure it with
the velcro fastener against slipping out.
7) Fix the belt bag with the velcro strap on its rear side
to your clothes.
8) To switch off the transmitter after operation, set the
power switch (2) to OFF. The display shortly indi-
cates and then extinguishes completely.
