SMDa Series
RM Remote Control Operating Instructions
RM Front Panel Controls
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 transmitter
will be set immediately.
Available adjustments:
• Audio input gain
• Frequency
• Lock or Unlock Modes
• Sleep Mode ON/OFF
When an SM Series Transmitter is in the power sav­
ing sleep mode, it uses only 20% of the normal bat­
tery drain, so battery life with be 5 times longer. This
is especially useful in situations where the transmitter
is buried deep inside costuming and there are wait­
ing periods between use. The transmitter can “sleep”
for several hours and then be awakened and adjusted
when the production is about to begin.
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.)
A single AA Lithium battery will operate
the RM for up to several years.
NOTE: 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 transmitter’s channel but will not affect any
other setting on the transmitter at that time.
RM Pages
The AUDIO button cycles through 4 pages:
1) Aud - set transmitter’s audio level
2) SLEEP/unSLP - cause transmitter to sleep or wake up
3) Loc/unLoc - lock or unlock transmitter’s buttons
4) Loud - adjust RM speaker volume
(press SEND button for a sample tone)
The FREQ button cycles through 2 or 3 pages, depend­
ing on the settings:
1) CH - set transmitter’s channel
(using block-independent hex code)
2) b - select a block number
(optional — uncovers next page)
3) 000.000 - set transmitter’s frequency in MHz
(avail. if a block is selected)
Speaker
Send Button
When the SEND button is pressed, the selected RM setting is
transmitted via the RM speaker to the microphone attached to
the SM Transmitter.
