IWM-402 Pendant Transmitter:
Remove the rear battery cover from the unit and insert a fully
charged battery, ensuring the correct polarity, if you don’t have
any fully charged batteries to hand use Hi capacity AA cell for
testing/set up purposes.
(IMPORTANT: see notes on page 16 regarding Chargers and
Batteries)
Choose the required transmission channel A or B, the IR
Receiver will operate on both, however if only one transmitter
unit is to be used please set to channel A, and replace the rear
cover.
Set the microphone volume level on the side of the transmitter to minimum and switch on the power, a green LED on
the front of the transmitter will indicate power is present. The channel indicator LED on the Receiver should illuminate
and should be the same as the pre set channel on the transmitter.
With the unit worn around the neck, gradually increase the volume level whilst speaking at a normal conversational
level, the sound should be heard through the system speakers as the volume control is advanced. Ideally the level
should be set at approx. 3/4 power before any feedback is possible, if feedback is encountered reduce the volume
of the transmitter, or alternatively adjust the level of the ampli
fi
er unit installed to compensate.
The microphone may be muted at at any time by pressing the mute button on the transmitter front, if muted this
will illuminate red, and allows the internal microphone to be temporarily switched off when privacy or con
fi
dential
conversations are required.
Check the IR Coverage (as per page 16)

These are intended primarily as a “roaming” microphone for pupil interaction.
Other than an On/Off switch, the handheld microphone option has no other controls. Operation
is indicated by a green LED which changes to red when the batteries are running low and
require re-charging (see section on chargers and batteries below). You will

hands free (just like the IWM-402 Pendant transmitter).
