Standby Mode
Standby Mode allows the user to verify or change the
transmitter’s operating frequency or audio input level
without transmitting any signals. Standby Mode can
only be invoked from a power off condition.
Quickly press and release both the AUDIO and FREQ
buttons simultaneously to enter and exit this mode.
Selecting the
Compatibility Mode
All Digital Hybrid Wireless™
receivers are capable of work-
ing with the Lectrosonics HM
transmitter. By selecting the proper compatibility mode,
the SM will also work with 200 Series, 100 Series and
IFB analog receivers, plus some other analog wire-
less receivers (contact the factory for details). Setting
the Compatibility Mode of the transmitter to match the
receiver is easily done via the Control Panel.
Note: RF transmission is prevented while selecting
Compatibility Modes. Also, the HM exits the
Compatibility Mode screen to Standby Mode. (See
Standby Mode, this section.)
Note: The unit comes from the factory configured
as a 400 Series transmitter.
1) Set the receiver’s audio controls to minimum.
2) Power up the HM and observe the Boot Sequence.
If the Compatibility Mode for the HM does not
match the corresponding receiver, then power off
the HM transmitter.
3) From a power off condition, hold down the Up
arrow, then simultaneously press the AUDIO and
FREQ buttons.
4) The LCD will display the current Compatibility
Mode. Use the Up or Down arrow buttons to set
the Compatibility Mode to match the corresponding
receiver.
The following Compatibility Modes are available:
• 100 Series mode:
CP 100
• 200 Series mode:
CP 200
• Mode 3 (Contact dealer for details): CP 3
• 400 Series mode:
CP 400
• IFB Series mode:
CP IFB
• Mode 6 (Contact dealer for details): CP 6
5) The Compatibility Mode selected in Step 4 will be
the current Compatibility Mode until reset using this
procedure. Pressing the AUDIO or FREQ exits into
Standby Mode. To power off from the compatibility
mode screen, press AUDIO and FREQ together.
Power Up and Boot Sequence
1) Ensure that good batteries are installed in the unit.
(See Battery Installation.)
2) Simultaneously press and hold the AUDIO and
FREQ buttons until the Power On Boot Sequence is
initiated. (See Power On Timer.) As the unit turns
on, the Modulation LEDs and PWR LED all glow red,
then green, and then they revert to normal opera-
tion, i.e., the Modulation LEDs glow according to the
audio level present at the Audio Input Jack and the
PWR LED glows green (with good batteries).

will stay energized and the display will return to the
previous screen.
