SMa Series
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 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 ways to unlock a locked
transmitter are to remove the
battery or unlock it via the
RM remote control.
Remote Control
Operation
Remote Control Screens SM Series transmitters may
be configured to respond to
signals from the RM remote control unit or to ignore
them. This setting is accessed by holding down the
Down arrow button while powering the transmitter on.
Use the arrow keys to toggle between “rc on” (remote
control on) and “rc oFF” (remote control off). The default
setting is “rc on.”
If a remote control signal is detected but the transmitter
is set to “rc oFF”, the message “rc oFF” will be dis­
played briefly on the transmitter’s LCD, to confirm that a
valid signal was received, but that the transmitter is not
configured to respond to it.
Functions available from the remote control are:
• Audio Level
• Frequency
• Lock/Unlock Buttons
• Sleep/Wake (power saving mode)
In sleep mode, the SM uses 20% of the normal amount
of current. For example, in sleep mode it will drain the
battery as much in five hours as it would do in one hour
of normal operation. Sleep mode can only be invoked
with the remote control, and can only be revoked with the
remote control or by removing the battery. When in sleep
mode, the PWR LED blinks green every few seconds to
indicate that the SM is asleep and not turned off.
Note: The RM is not included with SM Series
transmitters.

Battery Installation
The SM transmitter is powered by a single standard AA
1.5 volt battery. We recommend using lithium batteries
for longest life. In the SM, lithium batteries provide over
4.5 hours of operation at room temperature.
Note: Standard zinc-carbon batteries marked
“heavy-duty” or “long-lasting” are not adequate.
The battery status circuitry is designed for the voltage
drop over the life of lithium batteries.
To install new batteries:
1. Turn the Battery Cover Plate Thumbscrew coun­
terclockwise, open the battery compartment and
remove any old batteries.
2. Insert the new battery (or batteries) into the hous­
ing. The positive (+) battery terminal goes into the
transmitter first.
3. Replace the Battery Cover Plate and tighten the
Battery Cover Plate Thumbscrew.
