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SMisconguredtore-
spond to the remote control,
it will do so even if the but-
tons are locked.
• WhentheSMisasleep,itcan
only be awakened by the re-
mote control, or by removing
and reinserting the battery.
• WhentheSMisasleep,the
PWR led blinks green every
few seconds.

that would result in the same display being shown
again on the SM (for example tuning to the chan-
nel 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SMtorespond,
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.

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
on another transmitter during production.
