Frequency Select Switches - Lectrosonics MM400C Quick Start Manual

Frequency Select Switches

Two 16-position rotary switches adjust the center frequency of the carrier. The
1.6M is a coarse adjustment and the 100K is the fine adjustment.
Changing the Frequency
Locate the rotating watertight door on the bottom of the transmitter. Unscrew
the knob and pull the door outward, then swivel open to reveal two small
rotary switches. With the small screwdriver supplied with the kit, turn the left
switch to the first character in the two-digit Transmitter Frequency Switch Set-
ting code, then turn the right switch to the second character of the two-digit
code. For example: the frequency is 623.000, and the two-digit Setting code
is 56, thus the lefthand switch on your transmitter should be set to "5" and the
righthand switch to "6".
Note: If you are using a receiver with a frequency scan function, find
a clear frequency with the receiver, then set the transmitter to the
frequency selected with the receiver. With Lectrosonics 400 Series
receivers, a front panel LCD character display will indicate the correct
transmitter switch settings as a two-character alphanumeric hex code
once a clear frequency has been located with the scan function (if the
receiver is so equipped).
