The M175DC transmitter features a wide range input

limiter to guard against overload distortion and allow

maximum signal to noise ratio. The following procedure

will adjust the wireless system to take full advantage

of the limiter action to prevent excessive output level

from the receiver from overloading the recorder. This

will also maximize the signal to noise ratio of the audio

being recorded.

Note: This procedure assumes the receiver is

connected to an antenna and output connector

in the same conﬁguration and under the same

load conditions that will be experienced in real

operating conditions.

1. Install battery in transmitter and attach microphone

and set transmitter MIC LEVEL Adjustment to near

maximum clockwise position.

2. Turn on transmitter and place microphone near a

sound source, such as a portable radio.

3. Ensure the receiver’s Power and Code LED indica-

tors are glowing.

4. With the sound source (your portable radio) set

between stations, adjust its volume so that the 0 dB

Modulation LED on the receiver ﬂickers slighty.

5. Leave the portable radio running and adjust the

receiver’s Audio Output Level Control so that the

audio input to the recorder is just below the maxi-

mum that the recorder can handle.
