Channel Selection: Receiver
Each Receiver has 100 user-selectable
channels to choose from. You can
either select a channel manually or by
pressing the SCAN button, which will

ended):
A) Make sure the transmitter(s) is
OFF before pressing this button.
When this button is pressed, the
receiver will cycle through all
100 channels and select a clear
frequency. (This process takes
about 20 seconds.)
B) Once the receiver selects the
clear channel, you will need to
select the same channel on the
corresponding transmitter
(handheld or belt-pack). See pages
11 and 16 for instructions.
NOTE There are 3 different groupings
of 100 channels available. When
the system is powered ON, the
two letters that initially blink in the
channel window on the receiver
indicate the frequency group (see
chart on page 25 for further details).

Transmitter Mute
The mute switch turns the
transmitter’s audio signal ON and
OFF. The audio is muted when the
RED LED is flashing.
Sensitivity Level
This function allows the user to set
the gain structure of the microphone
to best fit the voice level of the
person speaking into it. A person
with a very loud, booming voice may
want the microphone set to sensitivity
level of 1 or 2. A person with a very
soft voice will be better off with the
microphone set to a sensitivity 3 or 4.
To change the sensitivity setting:
1. Press the UP button 3 times to get
to the Sensitivity Level screen.
2. Press and hold the SET button until
a blinking cursor appears.
3. Use the UP and DN buttons to
make a selection (1-4).
4. Press and hold SET until the
blinking cursor disappears.

5. BATTERY LIFE INDICATOR AND BATTERY-
TYPE ON HANDHELD MICROPHONE
Battery Life Indicator
The battery life is shown on the
primary screen of the LCD. The 7-step
fuel gauge acts as a detailed guide to
show the actual life of the battery.
Battery Type
The transmitter will operate with
either standard AA alkaline batteries
or nickel metal hydride (NiMH)
rechargeable batteries. Since these
types of batteries have different
characteristics, it is important to set
the transmitter to the appropriate
type of battery being used so that
the Battery Life Indicator will operate
properly.
To change the Battery Type setting:
1. Press the UP button 2 times to get
to the Battery Type screen.
2. Press and hold the SET button until
a blinking cursor appears.
3. Use the UP and DN buttons to
make a selection.
4. Press and hold SET until the
blinking cursor disappears.

MICROPHONE
Replacing the Batteries
1. Unscrew the end cap to reveal the
battery compartment.
2. Remove or replace the batteries as
shown. The microphone requires
two AA sized batteries stacked
end to end.
3. Note the polarity in the battery
compartment.
IMPORTANT: Replace batteries
with the same type, (alkaline or
NiMH), that were installed in your
Handheld Microphone. Lightspeed
recommends Panasonic or Energizer
batteries. Duracell may not work
properly.
