to see error messages displayed on-screen, select the “screen” option
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 status/error messages also appear in the lcd status display window near the keypad at the rear of the projector. they are accompanied by their corresponding 2-digit error code next to the keypad, evident at a greater distance. normal operation is indicated by the “00”status code.
user errors invalid user entry
input signal errors
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.
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
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 “status” led, and a related text message appears in the lcd status display window. a system malfunction can be cleared with exit exit from presentation level, but may indicate the need for service by a qualified service technician.
system messages appear on-screen only if display error messages has been set to “screen” or “all”.

the status led codes
if the status code display on the back of the projector shows one of the following values, you have encountered a likely system error requiring the attention of a qualified service technician (see system warnings and system errors, above). acknowledge and clear the error with exit exit from presentation level, or try resetting the projector by powering it off and on again, cooling when necessary. consult table 3.1 and contact your dealer if the problem persists.
the specific code number identifies the source of the error detected, and is particularly useful in cases where the projector is too far away to read the accompanying text message in the lcd status display window. for example, the code “21” means the lamp could not be turned on. error codes for this projector are listed in table 3.5.
if you encounter a system error, clear it with exit exit . if necessary, try resetting the projector by powering it off and on again (cooling if necessary). contact dealer/factory if error persists.
