LCD Backlight Settings

The LCD backlight can be set to stay on continuously or
turn off after either 5 or 30 minutes. Hold the UP arrow
in while powering up the unit to enter the setup screen.
Press the AUDIO button repeatedly to step through the
setup items to reach the backlight settings screen.
Use the UP or DOWN arrow button to select the desired

Setting Transmitter Operating Frequency

Frequency displayed
in MHz
Frequency displayed as
two-digit hexadecimal
number
1) If the LCD is displaying something other than the
Frequency Screen, press the FREQ button on the
HM Control Panel 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
that corresponds the equivalent Lectrosonics
Frequency Switch Setting.
2) While holding the FREQ button, use the UP or
DOWN arrow buttons to move the operating fre-
quency up or down in 100 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 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-posi-
tion rotary switches. The HM offers the ability to set
the operating frequency in a similar manner. Pressing
the FREQ button while the LCD displays the operat-
ing frequency in MHz will change the display to show
the equivalent two-digit hexadecimal frequency select
switch setting. Simply press the UP or DOWN arrow to
increase or decrease the operating frequency.

The operating frequency of the
HM can be displayed either in
MHz or as a two-digit hexa-
decimal number. The example
of the two-digit display shown
here indicates CH (channel)
and 2C as the frequency.
The frequency can be set with
the unit in standby mode or
when powered up for normal
operation.

ter's controls are locked.
The LCD will display the locked condition as long as the
arrow buttons are held, then revert back to the previous
screen when either button is released.
With the controls locked, the AUDIO and FREQ buttons
can still be used to display current settings. Any attempt
to change a setting by pressing either the UP or DOWN
arrow button will result in an on-screen Loc reminder
that the controls are locked. Remove the batteries to
unlock the control panel.
Important: Once the transmitter is locked,
it cannot be unlocked or powered off using
the buttons. The only way to unlock a locked
transmitter is to remove the batteries.
