Portable Wireless Sound System

7) Position the microphone on your person in the location it will be during actual operation. If you are using the

headset microphone, turn the white knob on the headset fully clockwise (maximum). The microphone should be

within 3 inches of the mouth to minimize the possibility of “feedback.” If the headset mic is being used, position the

mic element at the corner of the mouth and rotate the white volume control knob fully clockwise.

8) A small screwdriver is supplied with the transmitter. The screwdriver is used to adjust the audio gain of the

transmitter to match your microphone and your voice. The adjustment is made while observing the MOD LEVEL

lamps on the LONG RANGER III control panel:

a) Speak at the voice level you will be using during actual operation.

b) While speaking, adjust the transmitter gain with the screwdriver until the green MOD LEVEL lamp on the Long

Ranger III control panel is lighted or flickers and the red MOD LEVEL lamp blinks only on the loudest words.

Raise and lower your voice while observing the lamps. The red lamp should blink occasionally.

9) You may now adjust the WIRELESS MICROPHONE VOLUME control on the control panel to a level where

everyone can hear. You will probably have to do this in several steps. If you attempt to adjust the volume yourself

while standing and transmitting just behind the unit, you will likely have a “feedback” problem. It is convenient to

have another person adjust the volume while you transmit from a position 20 feet or more behind the unit.

REMEMBER--the transmitter gain control is used only to adjust for proper MOD LEVEL lamp indications. DO NOT

use it to adjust the output volume of the LONG RANGER III speaker. Different voices and different microphones will

usually require readjustment of the transmitter gain control, so check the adjustment frequently. If several different

people will be using the system and there is not time to make the adjustment for each individual, adjust it for the

loudest voice.

While speaking, Adjust the

transmitter as you observe

the LEDs on the receiver.
