Any keypad entry not recognized by DLV 1280 will trigger an on-screen error
message describing the problem. For example, if you specify a source or channel
that has not been defined, the message "Invalid Channel will appear. Or if you
try to enter the wrong password, you'll see "Invalid Password". Press any key to
confirm the message and eliminate the message box.

Input signal errors messages appear when you are in presentation level (i.e.,
when there are no menus present) and have selected an input on which the
projector detects a problem. While menus remain operational and pressing any
key will temporarily remove the message from the screen, you must resolve the
signal problem in order to permanently eliminate the message.
NOTE: Input signal messages appear only if the
menu is set to
The message "No signal" appears when there is no signal on the selected input.
Both HSYNC and VSYNC are inactive and the screen background is black.
Correct the signal or select another input.
The message "Bad Sync" is displayed when HSYNC or VSYNC are active but
the signal cannot be displayed. Such a condition occurs when only one of the
two signals is present, or when either signal is unstable or of the wrong
frequency. Correct the signal or select another input.
In addition to the common "Bad Sync" and "No Signal", 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 channel 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 is.
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 steady red "Power" LED and a flashing red-and-yellow error
code on the "Status" LED. This condition indicates the need for service by a
qualified service technician.
