Various Settings in MIW333
Channel Selection:
First open the cover of MIW333's battery compartment by pressing its release buttons on
both sides. There are 2 channels for selection, namely "A" and "B" A stands for 2.08MHz
and B stands for 2.54MHz.
Making Changes to MT:
Low-impedance "MT" gain control is located inside the battery compartment. It can be
adjusted by using a small screw driver to rotate till a desired audio output level is selected.
*Operating times are approximate and not guaranteed.
Battery installation/replacement
To install the batteries, first open the battery compartment by pressing the release
buttons on both sides of the MIW333. Batteries used are 2 pcs of NiMH 1.2V/2100 mAH
type(rechargeable) or Alkaline type(not rechargeable). When inserting batteries, please
place them according to the correct polarity.

CAUTION!!
The above chargers are specially designed for Ni-MH battery used in portable
transmitters/receivers only. Before charging, please make sure that the batteries are
Ni-MH rechargeable type.
Never try to charge an ordinary Zinc oxide or Alkaline battery as this may result in
explosion or re.

Charging the transmitters:
1.Make sure that the batteries installed in the transmitter are rechargeable NiMH type
and transmitter power has been turned off.
2.Connect the adaptor to the DC IN port of XC33 with its end to the wall outlet or DC
output of PIRA250.
3.Place the transmitter into the slot and charging process will start automatically.
4.When another transmitter has to be charged simultaneously, simply connect a
charging cable between the external charging port and this transmitter.
5.There are 2 sets of LED to indicate the charging condition of both transmitters.
The left set indicates the front transmitter and the right for the rear one. During
charging the RED LED will keep lit. When charging is nished, the process will stop
automatically and the GREEN LED will light up.

CAUTIONS:
‧Do not cover the infrared emitter area of the wireless microphone or the surface of the
infrared sensor, which may disturb the unit and cause abnormal operation.
‧Since the unit uses infrared reectance. Do not expose receiver to the black ceiling or
wall which may cause abnormal operation.
‧Do not use the microphones near speakers which may cause feedback.
‧Prevent the microphone from getting wet and avoid dropping.
‧Do not replace the battery when power is on.
‧Do not install the unit near heat source or in a place subject to direct sun-light, excessive
dust, mechanical vibration or shock.
OPERATING THE SYSTEM
1. Plug the adaptor in a nearby outlet and then connect the DC plug of adaptor to your
receiver.
2. Connect the receiver to speaker and turn on the PIRA250.
3. Slide the power switch of microphone to "ON". Then the channel indicator of receiver
will light up.
4. Adjust the volume control of amplier to a comfortable level.
5. Find the best position with a wide view of the room then set the receiver.

Ceiling Sensor PIRS360
PIRS360 has a wide reception of 360-degree angle to see the entire room at once.
Users can select 1, 2 or more PIRS360 to operate with PIRA250 receiver according to
different locations. Below are 2 examples for sensor placement of 1 and 2 PIRS360 in two
applications.
A.In an ordinary space such
as a classroom
1.Locate the PIRS360 sensor in
the middle of the ceiling (as
illustrated in below picture).
2.Connect the sensor cable to
PIRA250.
3.Turn on the IR system and
amplier then operation can be
started.
B.In a larger space such as
a tness center
1.Locate 2 PIRS360 sensors on
the suggested positions on the
imaginary catercorner of the
ceiling (as illustrated in below
picture).
2.Connect both sensor cables to
PIRA250.
3.Turn on the IR system and
amplier then operation can be
started.
