MIC JACK
The Microplug (2.5 mm) input on the transmitter accommodates 2 wire positive bias lavalieres. A waterproof mic
connector is available from Lectrosonics as an assembly kit. A Switchcraft 850 connector can be used in an emer­
gency though it is not waterproof.
See the separate sheet titled “Waterproof Microplug Wiring” regarding the correct
connections for various microphones, and other sources.
ON/OFF SWITCH
There is no on/off switch for this unit. Simply remove the battery to turn the unit off. There will be a thump in the
receiver when the transmitter battery is removed, so turning the received audio off in the main sound system may be
necessary.
“POWER” LAMP
Glows green when the battery is good. When the lamp glows red, there is about 30 minutes of operation left with the
recommended lithium battery. An alkaline battery will have about 20 minutes of life left. The lamp will flash red when
there are only a few minutes of life. A NiMh battery will give little or no warning when it is depleted. If you wish to
use NiMh batteries in the MM200, we recommend trying fully charged batteries in the unit, noting the length of time
that the batteries will run the unit and in the future use somewhat less than that time to determine when the battery
needs to be replaced. A weak battery will sometimes light the POWER LED to the “good” green indication immedi­
ately after being put in the unit, but will soon discharge to the point where the LED will go red or shut down, just like a
flashlight with “dead” batteries.
FREQUENCY ADJUST
These two rotary switches adjust the center frequency of the carrier. The 1.6M is
a coarse adjustment and the 100K is the fine adjustment.
Unscrew the knurled knob a few turns to loosen the water tight cap to gain
access to the two frequency switches.
