2.6 Main Screen Annunciators:

Located between the RPM and M.P. instruments on the Main Screen
are the following annunciators:

Fuel - When the estimated total fuel drops below approximately
45 minutes the “FUEL” annunciator will blink. The trigger level is based on 75% engine power and a fuel
specific of .08 gal/hr/Hp. The Low Fuel Trigger is set by Electronics International based on the aircraft data
provided.

Switch – When the “Recurring Fuel Alarm Qty” has been burned the “SWITCH” annunciator will blink.
This provides a reminder for the pilot to switch fuel tanks. The “Recurring Fuel Alarm Qty” can be set or
disabled in the “Fuel Alarm and Unit Info”screen, found in the User Setup Screens Menu (see section 6).

Secondary Screen Annunciator – If a function with a red and/or yellow limit is placed on the Secondary
Screen and the function is operating in a yellow or red range, the name of the function (in this case VOLTS)
will blink in the color of its operation. All functions monitored by the CGR-30P with yellow and/or red
range markings are either viewed or annunciated on the Main screen.

2.7 External Master Caution and Warning Lights:

A red external Warning Light and a yellow Caution Light (provided with the CGR) may be mounted in front of the
pilot, high on the aircraft instrument panel. These lights provide a heads-up visual warning. The red Warning Light
will blink any time the operating level of any monitored function reaches a red operating limit and the
yellow Caution Light will blink any time the operating level of any monitored function reaches a
yellow operating limit.

Pushing the Exit Button while viewing the Main screen will acknowledge the blinking and the blinking
will stop. Also, acknowledging a voice warning using the external “Voice Alarm Control Panel” will
stop the blinking of the Caution and Warning Lights.

Acknowledging a yellow blinking display will cause the yellow Caution Light to go out. Acknowledging a red
blinking display will cause the red Warning Light to stop blinking and go solid red. If at any time another function
reaches a red and/or yellow operating limit, the approprate Caution or Warning Light will once again blink.

2.8 Voice Alarm Control Panel (OEM Only):

The Voice Alarm Control Panel is an external panel used to control the voice warnings provided by the CGR. The
CGR voice warning system is a powerful system that provides an immediate and intelligent audible warning
regardless of the pilot’s head position or focus. The instant an operating level of any function reaches a red and/or
yellow operating limit, a chime will sound in the headset and a pleasant female voice will annunciate a phrase, such
as: “Check Oil Pressure,” or “Check Fuel Pressure.”
