Frequency Screen.
Note
The default is to display the operating frequency in MHZ. Pressing
the FREQ button again displays the operating frequency as a two-
digit hexadecimal number that corresponds the equivalent
Lectrosonics Frequency Switch Setting.
2) Use the Up or Down arrow buttons to move
the operating frequency up or down in 100
kHz increments from the current setting.
kHz increments from the current setting.
Note
The operating frequency displayed on the LCD wraps as it reaches
the upper or lower end of its range. Thus, if you intend to move the
operating frequency from the lower end of the range to the upper
end, it may be faster to do this by using the Down arrow until the
end, it may be faster to do this by using the Down arrow until the
frequency wraps to the upper end.
Most Lectrosonics receivers indicate the
operating frequency both in MHz and as a two
digit hexadecimal number.
This conforms to the
Lectrosonics tradition of
setting the operating
frequency using two 16-
position rotary switches.
The SM offers the ability to
set the operating frequency
in a smililar manner.

The front panel Modulation LEDs indicate limiter activity.
(See chart below.) Once set, the transmitter’s audio
level setting should not be used to control the volume of
your sound system or recorder levels. This gain adjust-
ment matches the transmitter gain with the microphone’s
output level, the user’s voice level and the microphone’s
position.

Note
Different voices will usually require different settings of the AUDIO
control, so check this adjustment as each new person uses the
system. If several different people will be using the transmitter and
there is not time to make the adjustment for each individual, adjust it
for the loudest voice.
1) Mute the main sound system, then insert the
microphone plug into the input jack, aligning
the pins and ensuring that the connector
