Step 4:
1. Make sure:
a. 750iR is switched ON.
b. LightMic is switched on and the
triangle-shaped is glowing red.
c. IR indicator on the 750iR is glowing
(to the left of A VOLUME).
2. As you speak into the microphone the
AF indicator light (to the left of A
VOLUME) on the 750iR will flash on
and off as the voice volume increases
and decreases.
3. While speaking at a normal level,
slowly turn the A VOLUME knob
clockwise to increase the volume of
the loudspeaker(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.

1. Ensure the HM-70 Handheld Microphone is turned OFF
(ON/OFF switch on the side of the unit). The LES 750iR can
be left on, but must be connected to AC power in order
to charge the microphone.
2. The HM-70s rechargeable batteries are
factory installed. Plug the smaller end of
the charging cable firmly into the jack
labeled CHARGER on the side of the
HM-70. Connect the larger end of the
charging to one of the CHARGE jacks
on the back of the LES 750iR.
Volume is set by adjusting the
volume control on the LES 750iR.
3. The power indicator light next to the
power switch glows green when the
cable is connected and charging
correctly. The light goes out when
fully charged.
