LOCATION AND FUNCTION OF PARTS AND
CONTROL OF MICROPNHONE (IWH-201)
1.Grille cover
2.Low battery indicator
The green LED showed the battery in full enough power.
The red LED showed the battery is weakly. Recharge the battery.
3.Power switch
Slide to turn microphone on.
4.Infrared emissionsource
Transmitting the infrared ray which carrying voice.
5.Power Selector Switch (Lo/Hi)
This switch changes transmitting power 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 thetransmitting distance may be insufficient. Set the switchto Hi position.
Factory setting is Lo position.
At Hipower operation, operating time is approx.4 hours.
(About half timeof Lo power operation.)
Turn the battery cover to counterclockwise and pull out. As shown in figure.
Make sure thepower switch is in the OFF position when replacement battery.
Make sure thebattery polarity is correction when installationthe new battery.
REPLACEMENT OF BATTERY(IWH-201)
