DLV 1280 User's Manual
If you would like to be notified on-screen of such errors, select the
Screen
option
from the
Error Msgs
pull-down list (in Preferences menu). If you would like to
be notified via an RS-232 message only, select the
RS232
option instead. For
both types of notification, select
All
. To disable error messages (except for
invalid user entries), select
Off.
Invalid User Entry
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.
NOTE: Displaying of “Invalid User Entry” messages cannot be disabled, even if
Error Msgs
in the Preferences menu is set to
Off
.
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
Error Msgs
in the Preferences
menu is set to
Screen
or
All.
No Signal
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.
Bad Sync
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.
Other Signal Error Messages
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.
