Lectrosonics SMa Series, Instruction Manual, Page: 17 / 24

Super-Minature Belt Pack Transmitters
Operating Notes
• The sensitivity to the remote
control varies with the trans­
mitter’s audio level setting
and the microphone used, but
it is always possible to make
it work with a sufficiently loud
remote signal at close range.
• If the SMa is configured to
respond to the remote con­
trol, it will do so even if the
buttons are locked.
• When the SMa is asleep, it
can only be awakened by the
remote control, or by remov­
ing and reinserting the bat­
tery.
• When the SM is asleep, the
PWR led blinks green every
few seconds.
• If a remote command is sent that would result in
the same display being shown again on the SM (for
example tuning to the channel already displayed),
a row of dashes is displayed briefly, as a signal that
the command was received, but it didn’t change
anything.
• If you are having trouble getting the SMa to re ­
spond, make sure you aren’t covering the RM’s
speaker with your thumb, and/or turn up the RM’s
speaker volume on the “Loud” page.
• If the RM is set to a different block number than
the transmitter and an attempt is made to set the
transmitter’s frequency in MHz, the command
will still work. The transmitter is simply set to the
corresponding channel in the correct block, with a
matching hex code.
• Since all SM transmitters respond to the same sig ­
nals, take care that the remote control is presented
only to the desired transmitter, with the minimum
speaker volume necessary to do the job reliably.
Note: The audio signal from the RM will change
the settings of all transmitters within range.
Experiment with this to prevent accidental changes
to another transmitter during a production.
The RM should be held close enough to the microphone to
change the settings on the intended transmitter, but not be so
loud as to affect other transmitters nearby.
