The RM unit gives you remote control of SM Series
transmitters using an audible tone delivered to the
transmitter's microphone. Operating parameters on the
transmitter can be set by holding the speaker on the
RM close to the microphone and pressing the pushbut-
ton. A "dweedle" tone will play from the RM speaker
into the microphone and the parameter on the transmit-
ter will be set immediately. Adjustments can be made
to set:
• Audio input gain
• Frequency
• Lock or Unlock Modes
• Sleep Mode ON/OFF
When an SM Series Transmitter is in the power saving
sleep mode, it uses 20% of the normal battery cur-
rent. The math is straightforward: having the transmitter
sleep for five hours is equivalent to using it normally for
one hour.

Powering the RM on and off

To turn the RM on or off, press the AUDIO and FREQ
buttons together briefly. The unit powers up on the page
that was displayed when the unit was powered off last.

Principles of Operation

The RM user interface is organized into pages which
are accessible via the AUDIO and FREQ buttons. Once
on a page, settings can be adjusted with the UP and
DOWN arrow buttons.
To change a transmitter's setting via the RM, it is neces-
sary to dial in the new setting on the appropriate page
on the RM, and then press the SEND button (on the
side, near the speaker). The speaker should be uncov-
ered and held within a few inches of the transmitter's
microphone. (The longest usable range is about 6 feet,
depending on the microphone and volume settings
used.)
Only the specific function displayed is altered. For
example, if the remote control is on the CH (channel)
screen, pressing the send button will set the transmit-
ter's channel but will not affect any other setting on the
transmitter at that time.
