Operating the LightMic

a.The LightMic has a built-in microphone. Once the transmitter is switched on, the microphone is activated.

b.The LightMic may be used as a hand- held mic or a hands-free pendent style microphone by clipping the LightMic on the supplied lavaliere cord.

Place the lavaliere cord around your neck, and adjust the length so the top of the LightMic rests on the collar bone.

c.On the side of the LightMic is the Chan- nel select switch. Slide the switch to the “A” position. (If a second LightMic is used for simultaneous operation, set one LightMic to Channel A and the second LightMic to Channel B.)

d.Slide the ON/OFF switch on the side of the LightMic to ON. The triangle- shaped light on the front glows red, indicating the microphone is charged and ready for use.

e.When the LightMic transmitter ON/OFF switch is slid to OFF, the microphone power is turned off.

Adjusting Volume

Volume is set by adjusting the volume control on the LES 780iR.

a.Ensure the LES 780iR is switched ON.

b.Ensure the LightMic is switched ON and the triangle-shaped LED on the front of the LightMic is glowing red. The IR 1 LED next to the A VOLUME knob on the LES 780iR will also glow, indicating that the LES 780iR is receiving the LightMic signal and is ready for use.

c.Adjust the volume of the receiver by turning A VOLUME clockwise.

d. Speak at a normal level and slowly turn the volume knob clockwise to increase the loudness of the speaker(s) until the sound level is adequate for the room.

[note:]

Feedback or “squealing” may occur if the volume is set too high. Reducing the loudness of the speakers with the volume control usually eliminates feedback.

Operating two microphone/ transmitters simultaneously

The LES 780iR has two independent receivers—Channel A and B. This makes it possible to operate two microphones simul- taneously. Follow the instructions below when using a second microphone:

a.Set each microphone/transmitter to separate channels. For example if you are using two LightMics, set one to Channel A and the other to Channel B. If you are using one LightMic and one HM-70 handheld microphone, set the LightMic to Channel A and the HM-70 to Channel B.

When the LES 780iR is receiving a signal from the microphone/transmitters:

IR 1 indicator to the left of the A volume knob will glow red on the LES 780iR when Channel A on the LightMic is selected

The IR 2 indicator light to the left of the B VOLUME knob will glow red when Channel B is selected.

When simultaneously operating two microphone/transmitters, both indicator lights will glow.
