The Gamut display modes can alert you whenever a signal exceeds a selected
limit. You can set alarm limits for both the Diamond RGB display and Arrow-
head composite display. The alarm can take the form of an alarm message in the
lower left corner of the CRT or a flashing of the MON OUT signal.
To set either the RGB or composite alarm, follow these steps:
1. Press the CONFIG button and select the GAMUT menu.
2. Select the type of GAMUT CHECK from these choices:
H CMPST (composite) for the Arrowhead display
H RGB for the Diamond display. RGB mode checks the R, G, and B
signals for transitions below 0 mV and above 700 mV.
H BOTH enables RGB and CMPST gamut checks.
3. Select the type of ALARM DISP (display) you want from:
H SCREEN places an error message at the lower left of the CRT.
H PIX MON flashes the analog output monitor signal in the area that
exceeds the limits.
H BOTH enables both SCREEN and PIX MON alarm displays.
4. Set the adjustable limit cursor to 100, 110, 120, or 131 IRE for NTSC or
700 mV or 950 mV for PAL.
When an alarm condition occurs, a message appears or the monitor flashes for at
least one second. In addition, pin 16 of the Remote rear panel connector is pulsed
low. Refer to Remote Connector discussion on page B–2 for more information.
