Locking/Unlocking The Control Panel; Remote Control Operation - Lectrosonics SMV-941 Instruction Manual

SMV Series
FREQ Button
The operating frequency can be adjusted according to
the frequency in MHz or a two-digit hexadecimal code.
Press the button repeatedly to switch between the two
displays. The display switches when the button is first
pushed; push and hold the button in the desired mode
and use the UP and DOWN arrow buttons to make the
adjustment.
In this example, the same frequency is displayed in
MHz and the equivalent hex code.
The hex code is a hexadecimal sequence that pro-
gresses upward from lowest to highest frequency using
the numerals and letters from 0 through F. When the
frequency is on a 100 kHz step, the hex code is only
two digits, as shown above, which is easy to remember.
When the step size is set to 25 kHz, additional charac-
ters are used to denote the exact frequency with four
characters.

Locking/Unlocking the Control Panel

When the timer reaches zero, the buttons on the control
panel are locked.
With the controls locked, the AUDIO and FREQ buttons
can still be used to display current settings. Any attempt
to change a setting by pressing either the UP or DOWN
arrow button will result in an on-screen Loc reminder
that the controls are locked. Remove the batteries to
unlock the control panel.
Important: Once the transmitter is locked, it
cannot be unlocked or powered off using the
buttons. The only ways to unlock a locked
transmitter are to remove the battery or unlock it
via the RM remote control.

Simultaneously pressing and
holding both the UP and
DOWN arrow buttons during
normal operation starts the
Lock timer. The timer starts at
three and counts down to zero.

Remote Control Operation

Remote Control Screens
The remote function is enabled in the UP arrow power
on options (see previous section). If a remote control
signal is detected but the function is no enabled, the
message rc oFF will be displayed briefly on the trans-
mitter's LCD.
Remote functions available are:
• Tx Input Gain
• Sleep/Unsleep
• Lock/Unlock
• Frequency
• Tuning in 25 kHz steps
• Changing the low frequency roll-off setting
• Turning on/off the PWR and Audio LEDs
• Input gain functions
In sleep mode, the transmitter uses about 20% of the
normal amount of battery drain. 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 the sleep mode, the PWR LED blinks green every few
seconds to indicate that the transmitter is asleep and not
turned off.
The transmitter can be
controlled by signals from
audio "dweedle" tones
generated by a mobile phone,
or with the Lectrosonics RM
and RM2 devices.
