3.9 Error Conditions; User Errors; Input Signal Errors - Runco Video Xtreme VX-40d Owner's Operating Manual

Occasionally the projector will encounter an error condition that can interrupt normal
operation. Such a condition can be caused by a simple invalid keypad entry, an input
signal error (most common) or a system error. The manner in which users are to be
notified of error conditions is set in the Menu Preferences menu:
• To see error messages displayed on-screen, select the "Screen" or "All" option.
(recommended by Runco)
• To be notified via a serial communication only, select the "RS232" option.
• To receive both types of notifications, select "All".
• To disable error messages (except for "invalid user key entry", which can't be hidden),
select "Off".
Note that a two-digit error code appears in the status LED display window located
beside the built-in keypad at the rear of the projector. Normal operation is indicated by
the "On"status code.

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".
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 of the wrong frequency. Correct the
signal or select another input.
