Lectrosonics SMQ - Manual (Page 8)

SM
Standby Mode
Quickly pressing both the
AUDIO and FREQ buttons from
rF OFF
a power off condition places the
unit in Standby Mode. In this
Standby Screen
mode, the screen displays “rf
OFF” to inform the user that the unit is not transmitting.
Holding the FREQ button in Standby Mode displays the
current operating frequency of the transmitter. The
operating frequency can be changed by holding the
FREQ button and pressing either the Up or Down
button. Release the FREQ button, then press and hold
it again to toggle the display between frequency in MHz
and the hex code corresponding to the equivalent
Lectrosonics Frequency Switch Setting.
Holding the AUDIO button in Standby Mode displays
the current audio input level setting. This level can be
changed by holding the AUDIO button and pressing
either the Up or Down button.
Quickly pressing both the FREQ and AUDIO buttons
simultaneiously when the unit is in Standby Mode
powers off the transmitter.
Remote Control Operation
Note: A remote control (Lectrosonics model RM) is
available to change certain settings on the SM in
situations where the controls would be difficult to
access, for example, when the transmitter has
been placed underneath an elaborate costume.
The RM is not included with the SM.
The SM transmitter may be configured to respond to
signals from the remote control or to ignore them. This
setting is accessed by holding down the 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
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 one fifth 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 occasinally to indicate that the SM is asleep and
not turned off.
Battery Installation
The SM transmitter is powered by a single standard AA
1.5 volt battery, while the SMD and SMQ use two AA
batteries. 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 counter­
clockwise, open the battery compartment and
remove any old batteries.
2. Insert the new battery (or batteries) into the hous­
ing. Take note of the polarity marked on the case
showing the location of the positive (+) and nega­
tive (-) terminals. The positive (+) battery terminal
goes into the transmitter first.
3. Replace the Battery Cover Plate and tighten the
Battery Cover Plate Thumbscrew.
