SM Screen Selections
Six screens are used to set up and operate the SM.
These screens are used to set the operating frequency,
adjust the audio modulation level, select the Compatibil
ity Mode or lock the control panel and power down the
transmitter.
Audio Screen
The Audio screen is the default
screen at the end of the power
up boot sequence. It can also
be accessed by pressing the
AUDIO button during normal operation.
The Audio screen displays the current audio input level
setting.
Frequency Screen
The Frequency Screen displays
the operating frequency in MHz
or as a two-digit hexadecimal
number that corresponds to the
equivalent Lectrosonics Fre
quency Switch Setting. Press
ing the FREQ button toggles
between the two displays.
When the operating frequency is displayed in MHz, the
decimal point also acts as the PLL lock indicator. If the
decimal point is constantly blinking or missing, this
indicates that the transmitter is having RF problems.
(See Troubleshooting, Receiver RF Indicator Off .)
Compatibility Mode Screen
Holding down the Up arrow
button while powering up the
SM opens the Compatibility
Mode screen. By using the Up
or Down arrow buttons, the user can select one of six
compatibility modes:
Note: RF transmission is prevented while selecting
Compatibility Modes. Also, the SM exits the
Compatibility Mode screen to Standby Mode. (See

While in the compatibility mode screen, pressing either
the AUDIO or FREQ button exits to standby mode. To
power off from the compatibility mode screen, press
AUDIO and FREQ together.
Lock/Unlock Screen
Simultaneously pressing both the Up and Down arrow
buttons during normal opera
tion starts the Lock timer. The
timer starts at three and counts
down to zero.
When the timer reaches zero, the transmitter'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 a reminder that the
controls are locked.
Important: Once the transmitter is locked, it
cannot be unlocked or powered off using the
buttons. The only ways to unlock a locked
transmitter are to remove the battery or unlock
it via the remote control. The remote control
will work only if the transmitter was previsouly
configured to respond to the remote control.
Lock mode does not persist when the power is
off.
Power On Timer Screen
Simultaneously holding the
AUDIO and FREQ buttons
when the unit is turned off
displays the Power ON Timer
screen. The screen counts up
from one and starts the Power On sequence when the
count reaches three. Releasing either button prior to
the Power On Timer screen reaching three puts the unit
in Standby Mode where the user can review transmitter
frequency and audio level settings without transmitting.
(See Standby Mode , page 8.)
Power Off Timer Screen
Simultaneously holding the
AUDIO and FREQ buttons
while the unit is operating
displays the Power Off Timer
screen. The screen counts
down from three and turns off
the transmitter when it reaches zero. Releasing either
button prior to the Power Off Timer screen indicating
zero returns the unit to normal operation and displays
the previous screen.
