SMART Sympodium projection cut off

Standard

ISSUE: when using a classroom equipped with a SMART Sympodium display, the image on the projector and/or display itself will sometimes appear cutoff, or may be “off the screen” to one side.

RESOLUTION: power cycle the Sympodium display using the power button on the front, top right corner.  Leave the projector on while you do this, and when the display powers up, the image should display properly in both locations.

Rossman AMP2x75 amplifier

Standard

ISSUE: frequent “clicking” sound heard over speakers

RESOLUTION: classrooms with this model amplifier may experience this clicking, which is an input-sensing relay within the unit opening and closing.  To resolve, change the “ON/AUTO” switch on the rear control panel from AUTO to ON.  This will leave the amp powered on, without the input sensing engaged, and should resolve the clicking.  This switch is the bottom-most switch on the rear panel, directly above the RCA input jacks.

ISSUE: audio output is very quiet, even with mixer and amp both turned all the way up

RESOLUTION: check that mono button is not engaged; when mono button is depressed, audio becomes very quiet.  Mono button is located to the immediate left of the Bass dial.
