observing that the word
“Off” appears in the LCD along with a counter.
2) When the counter reaches “0”, the unit turns off.
Note: If the AUDIO and FREQ buttons are
released before the LCD goes blank at the end of
the countdown, the unit will not turn off. Instead, it
will stay energized and the display will return to the
previous screen.
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 receivers are
capable of working with the
Lectrosonics SMDa trans­
mitters. By selecting the
proper compatibility mode, the SMDa will also work with
IFB analog receivers. 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 transmitter exits the
Compatibility Mode screen to the Standby Mode.
(See Standby Mode section)
Note: The unit comes from the factory with the
Digital Hybrid mode selected.
1) Set the receiver’s audio controls to minimum.
2) Power up the SM and observe the Boot Sequence.
If the Compatibility Mode for the SM does not match
the corresponding receiver, then power off the SM
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:
• 400 Series mode: CP Hbr
• IFB Series mode: CP IFb
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.
