The Channel A/B switch is located inside the battery compartment. The switch is set to Channel B at the factory.

1.Slide the power switch on the side of the HM-70 all the way up. The power indicator LED will glow red and stay on.

2.The center position of the power switch is MUTE. When in this mode, the HM-70 is transmitting a signal, but no audio can be heard through the system. This is useful if you wish to temporarily turn audio off during a private conversation.

3.Grip the barrel of the HM-70 in the center section just below the power switch. Avoid gripping the HM-70 around the bottom, covering the infrared emitters circling the base. This could interrupt signal trans- mission from the microphone to the receiver.

4.Speak directly into the microphone at a normal level. Slowly increase the B VOLUME until you can just hear your voice.

5.Slide the switch to the OFF position to turn off the HM-70. (Make sure the power indicator light is off.)
