Being the transmitter intended for mobile use
mainly, make sure that the battery is sufficiently
charged to sustain the desired activity.
Please note that the maximum battery life is
approximately 8-10 hours and, over the time,
due to the natural deterioration of lithium it may
reduce.
It is advisable to recharge the battery in
environments with temperatures between 10° C
and 30° C. Charging in other environments may
not be as effective.
Power Supply &
Charging
Make sure that the Micro-USB Cable (Pic. 2) is
connected to a wall power supply (not included
in the package) and to the dedicated port (Pic. 1)
located on the RIGHT SIDE of the transmitter.
Pic. 2 - Micro-USB Cable
To find out the state of the charge, observe the
Status LED (Pic. 1) which will be red when
the charge percentage drops below 20% and
during the charging procedure till 75%, while it
will be green with sufficient charge and when
charging is complete.
Powering On/Off
To turn on the transmitter, simply press and hold
the ON / OFF button located on the TOP SIDE of
the transmitter. As soon as the transmitter is
correctly switched on, the DISPLAY (Pic. 6) on
the front (Pic. 1) will show the channel on which
the transmitter operates.
Consequently, to proceed with the shutdown,
proceed by exerting the same pressure on the
ON / OFF button.
Audio Source
Whatever audio source you want to transmit, it
must be connected to the Audio Input on the
SUPERIOR SIDE of the transmitter (Pic. 1).
This means that if you have another type of
connector, you will need an adapter. Usually
most devices have a 3.5 mm output, so you
can use the AUX cable included in the package
(Pic. 3).

Mic
In order to spread your voice, you need to connect
a microphone compatible with the 3.5mm port
to the Mic Input located on the SUPERIOR SIDE
of the transmitter.
The SILENTSYSTEM® TX-400-MOBI kit does not
include a microphone. As a reference, you can
consider purchasing a Headband Microphone
(Pic. 4) or a Clip Microphone (Pic. 5).
Channel Selection
With the device switched on, the audio source
and the microphone properly connected, by
holding down the Mod key located on the
UPPER SURFACE (Pic. 1) the Display will begin to
flash.
Once done, simply use the Channel - and
Channel + buttons to select the one you want.
The same channel has to be selected on the
headphones to hear what is being broadcast.
