Texas Instruments MATRIX 3000 User Errors, f Invalid User Entry, Input Signal Errors, No Signal

Section 3: Operation

	User Errors	f Invalid User Entry
			A keypad entry not recognized by the projector triggers a short on-screen error
			message identifying the problem. For example, if you specify a channel number that is
			not available, the message “Invalid Channel will appear. Or if you try to enter the
			wrong password, you’ll see “Invalid Password”. Press	or	Exit	to clear the
			message and try again.
			NOTE: On-screen display of “Invalid User Entry” messages cannot be disabled, even
			if Display Error Messages has been set to “Off”.
	Input Signal Errors	f An input signal error message occurs if you are in presentation level (i.e., there are no
			menus present) and have selected an input on which the projector detects a problem.
			While menus remain operational and any key press will temporarily remove any
			displayed error message, you must resolve the signal problem in order to permanently
			eliminate the message.
			No Signal
			The message "No signal" occurs when there is no source signal detected at the
			selected input—both HSYNC and VSYNC are inactive and the screen background is
			black. Connect or correct the signal, or try another input.
			Bad Sync
			The message "Bad Sync" occurs when HSYNC or VSYNC are active but the signal
			cannot be displayed. Such a condition occurs when only one of the two sync signals is
			present, or when either sync signal is unstable or the wrong frequency. Correct the
			signal or select another input.
			Other Signal Error Messages
			In addition to the common "Bad Sync" and “No Signal” errors, you may encounter a
			signal error message indicating that HSYNC and/or VSYNC are either too fast or too
			slow. When such a message appears, check the frequencies shown in the Status menu.
			If they are correct, then the signal is not recognized by the projector. On some PCs
			you may be able to change the settings to generate a compatible signal. If the
			frequencies shown in the Status menu are incorrect, check the cabling to see where the
			problem might originate.
System Warnings / Errors		f When the projector encounters a system malfunction, either a System Warning
			message or a System Error message may appear. Both types of messages are
			accompanied by a numerical error code on the LED status display window next to the
			built-in keypad. A system malfunction can be cleared with	Exit	Exit	from
			presentation level, but may indicate the need for service by a qualified service
			technician.
			NOTE: System messages appear on-screen only if Display Error Messages has been
			set to “Screen” or “All”.
			System Warnings
			A system warning indicates that a system malfunction has been detected (see Status
			LED Codes, below). A system warning message replaces any input signal message
			and disappears when the input signal status changes. While the projector will remain
			operational, the message indicates the presence of a potentially serious problem that
