Lectrosonics M185 - Manual (Page 5)

CONTROLS AND FUNCTIONS (cont’d)
Since the internal circuits are all tightly regulated and the RF output stage has a separate discrete
regulator, the transmitter will continue to operate to a battery voltage of 6.5 Volts. From 6.5 Volts to 6
Volts, the transmitter will still operate, but with degraded performance. Please note that a weak battery
will sometimes light the POWER LED immediately after turn on, but will soon discharge to the point
where the LED will go out, just like a flashlight with "dead" batteries.
The combination of an accurate battery condition indicator and regulation of all internal circuits provides
much longer battery life, as well as consistent performance over the life of the battery.
MODULATION LEDS
Indicate the proper setting of the MIC LEVEL control.
LEVEL LED
Flickers or glows when sufficient audio is present.
LIMIT LED
Lights up when the audio volume level is high enough to cause limiting.
MIC LEVEL
Used to adjust the audio input level for the proper modulation.
ANTENNA
The microphone cord is used as the antenna. A dipole antenna is formed between the shield of the
microphone cord and the metal transmitter housing.
THE BELT CLIP
The belt clip may be removed for special applications by removing the two screws.
USE ONLY THE SCREWS THAT ARE SUPPLIED
The circuitry is tightly packed into this unit. Longer screws will permanently damage the transmitter!
