User's manual
Thank you for purchasing our infrared wireless microphone system. Please be sure to
read the manual thoroughly and keep it for future reference.
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 reflectance. Do not expose receiver to the black ceiling or
wall which may cause abnormal operation.
1. Do not have the microphone near the speaker because it may cause howling.
2. Do not drop and wet microphone.
3. Do not replace the battery when power is not off.
4. Do not install the unit near heat source or in a place subject to direct sun-light, excessive
dust, mechanical vibration or shock.
5. Do not use two A or B channels at same time because it may cause abnormal operation.

Charging the batteries of IWM-302:
When IWM-302 is on, the LED glows Green to indicate enough power. If red or no
light, the batteries might be weak or wrongly installed. Please check the
installation polarity again.
IWM-302 can be recharged by HC-37. To charge IWM-302, switch it off and connect
the adapter to a wall outlet. Slot IWM-302 into this charger and charging process
will start automatically. During charging, the" CHG"LED (red) keeps lighting up until
the "FULL" LED(green) lights up, meaning the batteries are full.
Please notice that this charger is specified to CHIAYO rechargeable batteries
only. Batteries with other specifications might not cause the charger to work
normally.

Power Selector Switch (Lo/Hi)(IWH-201)
This switch changes transmitting intensity of infrared ray. At Lo position transmitting
distance is approx. 20M and at Hi position approx. 30M.
If transmission system may pick up some noise at Lo position.
It means the transmitting distance may be insufficient. Set the switch to Hi position.
Factory setting is Lo position.
At Hi power operation, operating time is approx. 8 hours.
At Lo power operation, operating time is approx. 12 hours.
