Setup
a.
Check to ensure that the M-175 transmitter’s radio frequency channel is
the same as the associated COMTEK receiver’s channel. (Channels are
indicated by the rotary channel selector switches on the back of the
transmitter. See page 8.)
b.
Open the battery door cover on the transmitter (see page 4) and
insert a new nine volt alkaline battery (Eveready E522 or equivalent). This
type of battery will offer up to 14 hours of operation.
Replace
the battery before
every
use if
the demand for fail-safe operation outweighs battery cost.
The use of
carbon batteries is not recommended.
NOTE: If a rechargeable battery is to be used, ensure that it has been
allowed to charge at least twelve hours to bring it to full charge
(see page 5 for battery charger instructions).
c.
Connect the microphone to the transmitter by inserting the microphone
plug into the receptacle on the top of the transmitter. The transmitter is
operating when the transmitter power switch is turned on and the battery
status/on indicator illuminates.
NOTE: The 48-inch microphone cord also functions as part of the
transmitter’s antenna system. For optimum performance, this cord
should be fully extended. Coiling or bunching the microphone
cord may reduce the range of the transmitter. The transmitter
should be carried by the snap-on belt clip (included) or in a pocket
or belt-clip pouch.
d.
In a situation where an extremely loud voice or a very soft voice is used, it
is necessary to adjust the audio input gain control while observing the audio
“voice” level modulation indicator. A full bright LED indicates full audio
compression at 100% modulation. For best performance, the audio input
gain should be adjusted for some low level LED luminescence during
normal audio levels with occasional full bright peaks indicating 100%
modulation.
