Section 3: Operation

User’s Manual 3-67.

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.

• 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 “0n”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

Exi t

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.

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
