LED Control Operation and Status Indication
The ON/SLEEP state of the SLII can be determined by pressing the
CONTROL
button for less than 0.5 seconds. If the instrument is ON, the
status of the instrument will be shown by the LEDs. If the instrument is in
the SLEEP mode, all the status LEDs will light until the
CONTROL
button
is released. Once released, the status indication resumes.
Control of the instrument is performed by pressing and holding the
CONTROL
button until the control LED corresponding to the desired
operation lights. Releasing the
CONTROL
button when the desired control
LED is illuminated results in the corresponding operation being performed.
When pressing the
CONTROL
button each LED will light in sequence.
Continuing to press the
CONTROL
button will result in all LEDs being
off after the last LED lights. If you continue to hold the
CONTROL
button down, the sequence will repeat with the first LED. Releasing the
CONTROL
button after the last LED turns off and before the first LED turns
on will result in no action being taken by the instrument. This provides a
mechanism to cancel (or ignore) the button press.
The Instrument will turn ON from the SLEEP mode if a recording is sched-
uled to start.
