Setting Transmitter Operating Frequency

The Operating Frequency of the SM is displayed
either in MHz or as a two-digit hexadecimal num-
ber. Pressing the FREQ button toggles between
the two display modes. The frequency can be set
with the unit in Standby Mode or while powered up
for normal operation.
Note: You must first find a clear frequency
with the receiver, then set the transmitter to
match.
To change the Operating Frequency of the SM
Series transmitter:
1) Press the FREQ button to enter this screen.
Note: The default display is in MHz. Pressing the FREQ button again
displays the operating frequency as a two-digit hexadecimal number.
2) While holding the FREQ button, use the Up or Down arrow buttons to
move the operating frequency up or down in 100 kHz increments from
the current setting. Holding the Up or Down arrows will cause rapid
scrolling through the frequencies.
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
frequency wraps to the upper end.

adjusting the Low Frequency roll-off

Repeatedly press the AUDIO button until the LF
roll-off adjustment screen appears. Then press and
hold the AUDIO button while selecting the desired
roll-off frequency with the UP and DOWN arrows.
The roll-off frequency can be set to 35, 50, 70, 100, 120 and 150 Hz.
