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.)

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

receivers—Channel A and B. is 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
• e IR 2 indicator light to the left of the
B VOLUME knob will glow red
when Channel B is selected.
