Thank you for purchasing our infrared wireless microphone system. Please be sure to read the

user's manual thoroughly and keep it for future reference.

Cautions

Do not cover the infrared emitter area of the wireless transmitter or the surface of the infrared

sensor.

Do not use the transmitter too close to speakers to prevent feedback.

Do not replace the battery when power is on.

Do not install near heat source or in a place subject to direct sunlight, excessive dust,

mechanical vibration or shock.

Do not use two transmitters on one channel at same time because it will cause abnormal

operation.

6.Audio output connector for assistive listening device. The volume level can be adjusted

individually via the volume knob below.

7.Audio input for EMERGENCY OVERRIDE (EO). There are two input modes for EO, 100V

(high voltage) and LINE (low voltage). The sensitivity can be set by adjusting the EO SENS

knob and the EO volume can be controlled on EO LEVEL knob . When EO is activated,

all operation of this unit will be muted temporarily and emergency audio source will be

amplified through this input. This function is specifically designed for emergency or public

broadcast.

8.EMERGENCY OVERRIDE mode selector. 100V for high voltage. LINE IN for low voltage.

9.Sensitivity setting of EMERGENCY OVERRIDE (EO). Turn to decide the sensitivity value

that activates EO function.

10.Volume setting of EMERGENCY OVERRIDE (EO). Turn to decide an optimized volume

level.
