2)
Turn on the receiver and adjust the Long Ranger
volume to minimum.
3)
Turn on the transmitter. The RF LED on the re-
ceiver should come on.
4)
Hold the microphone as you will when you will be
using it.
5)
While speaking, adjust the transmitter gain until the
green MOD LEVEL lamp on the Long Ranger
control panel is lighted or flickers and the red MOD
LEVEL lamp blinks on the loudest words. Raise
and lower your voice while observing the lamps.
The red lamp should blink occasionally.
Occasional lighting of the LIMIT LED (about 10-15% of the
time) indicates proper operation
and optimum signal-to-noise ratio.
Even when the transmitter is limiting, little distortion is
produced because of the high linearity of the gain
control circuit in the H175.
6)
Adjust the Long Ranger volume level as necessary.
NOTES: The LEVEL control on the transmitter
should not be used to control the volume of your
sound system. This should be done using the
level control on the Long Ranger.
If the mic level is too high - the Red LED on the
Long Ranger will light frequently or stay on. This
condition may cause distortion.
If the mic level is too low — neither LED will light,
or the Red LED will light dimly. This condition will
cause hiss and noise. You may experience severe
reduction in apparent range if the transmitter gain
is too low. It may sound as if you are getting
dropouts. What is actually happening is that you
are hitting your noise floor because the S/N ratio
has been reduced by the low modulation.
The input limiter operates over a full 30dB range
regardless of the gain control setting. The Red
LED should flicker occasionally during operation.
