Display control buttons (Power, Mute, Mode) and LEDs — The
settings of the display control functions are customized for each
projector. These buttons function only after they have been
programmed on the System 7SC or System 5cr Plus.
Display power (Power) button and LED — Pressing this button
turns the projector’s power on/off. It may also be tied to a
Room function (System 7SC only) if programmed to do so.
The LED lights when projector power is on, and it blinks
during projector power-up/power-down. The power-up/
down delay times are set via the software that is included
with the switcher.
Display mute (Mute) button — Press this button to turn
the projector’s “mute” function on or off (to turn off/
on the displayed image) once the Mute button has been
programmed for use with the projector.
Mode button — For the System 5cr Plus, this button can be
programmed to switch the mode of the projector between
computer-video (RGB), S-video, and composite video.
For the System 7SC, this button can be programmed to
execute any RS-232 or IR command.
b
Volume control knob and LED — Turn this knob to adjust
the audio volume. For the System 7SC this affects the Variable
(preamp) audio output, not the fixed output. There is no
physical limit to this knob’s rotation. The LED blinks when the
knob has reached its functional minimum or maximum limit.
