If you are only using one of the two wireless systems, it
is best to use the wireless system built into the Long
Ranger and leave the Add-On receiver turned off. This
will prevent unwanted noise, hiss or static that could
occur in the unused receiver from entering the Long
Ranger.
Special Note to Dual Channel Users
1)
Set up the Long Ranger system according to the
Initial Equipment Adjustments on page 6.
2)
Leave the Long Ranger power turned on. Set both
volume controls on the Long Ranger control panel
tominimum.
3)
Turn the Add-On receiver power switch to “ON.”
Check to see that the power lamp comes on.
4)
Plug the microphone into the transmitter that is on
the same frequency as the Add-On receiver. The
plug on the microphone is a twist-lock connector.
Make sure there is a good connection. If you are
using the head set microphone, turn the white level
control knob on the headset fully clockwise (maxi-
mum).
5)
Install the 9 Volt battery into the transmitter, turn the
transmitter on and make sure the red LED on the
transmitter glows brightly.
6)
Check to see that the green “RF” LED on the Add-
On receiver glows steadily. This verifies that the
receiver is picking up a good radio signal from the
transmitter.
Initial Adjustments to the Add-On Receiver System
7) This is the most important step in the set up
procedure.
Place the microphone in the exact
position where you will be using it. Speak at the
same voice level that you will use during actual
operation. While you speak, use the supplied
screwdriver to adjust the gain control on the trans-
mitter side panel (see pages 5 & 7) while you
observe the MODULATION LEDs on the Add-On
receiver front panel. The green LEVEL lamp should
flicker or stay lit as you speak. The red LIMIT lamp
should blink only on louder words.
8)
Adjust the AUXILIARY INPUT VOLUME control on
the Long Ranger control panel for the necessary
loudness. If the transmitter gain controls have been
correctly set on both the Longer Ranger 4 and the
Add-On system, both volume control knobs on the
Longer Ranger 4 panel will be in about the same
position for equal loudness on both systems. It is
not unusual, however, that one of the volume
controls may need to be set higher or lower than
the other one in normal use. Adjust the controls
separately for adequate sound levels for each
microphone.
If it is necessary to use the Add-On receiver by itself,
turn the WIRELESS MICROPHONE VOLUME control
knob on the Long Ranger control panel to minimum.
Then set the AUXILIARY INPUT VOLUME for the
necessary loudness of the Add-On system.
