volume rotary knob near the upper left corner. COM 2 and NAV 2 circuit breakers on Avionics Bus 2

supply power to the GNS 430W.

NOTE:

The following operating instructions are applicable

to both the GNS 530W and GNS 430W

The GNS is self-contained with a single display and front panel controls. COM and NAV volume is

controlled via two small rotary knobs. COM/NAV frequency selection is controlled via the left dual-

concentric knobs. Pressing the knob toggles between COM and NAV frequency selection. There are

individual COM and NAV frequency flip-flop keys near the volume knobs.

The right dual-concentric knobs are used for page selection and entering data. The Small (Inner) knob

selects a specific page within a page group. Pressing the small knob turns the selection cursor ON and

OFF. When the cursor is ON, data may be entered in the applicable window by turning the small and

large knobs. In this case, the large knob moves the cursor on the page and the small knob selects

individual characters or values for the highlighted cursor location. The Large (Outer) Knob selects the

page group. When the cursor is ON, the large knob moves the cursor to highlight available fields.

There are dedicated ENT, CLR, and MENU keys on the right side of the unit. System messages are

viewable by pressing the MSG key at the bottom of the unit.

The GNS starts in normal mode when power is applied to the unit and the power switch is on. After

completing the self-test, the database confirmation page is displayed. Invalid or expired databases are

displayed in yellow. Press ENT to proceed to the INSTRUMENT PANEL SELF-TEST page. CDI/HSI

indications may be verified while this page is displayed. Press ENT to continue to satellite acquisition.

After a GPS position has been acquired, the unit will be ready for operation. During normal system

operation with all aircraft systems and avionics powered there should not be any system messages

displayed.

To enter into Configuration Mode for the GNS GPS/NAV/COM unit, verify the unit turned off. Apply power

to the GNS while holding the ENT key. Release the ENT key when “INITIALIZING SYSTEM” appears in

the upper left corner of the display.

Refer to the appropriate Modification Summary, Section 4, for further Configuration instructions.

2.3.3 GMA 347

The GMA 347 is powered by Avionics Bus 2 which is normally controlled by the Avionics Bus 2 master

switch. The GMA 347 also contains a power switch which is controlled by the Pilot’s volume rotary knob

near the left side of the unit. An AUD/MKR circuit breaker on Avionics Bus 2 supplies power to the GMA

347.

The GMA 347 is self-contained with front panel controls. Audio source selection is controlled by the top

row of buttons with green LEDs indicating selected sources. COM MIC selection buttons are on the

bottom row with a green LED indicating the selected COM MIC. The left dual concentric knob controls

pilot intercom volume and squelch. The right dual concentric knob controls copilot intercom volume and

squelch.

The GMA 347 starts in normal mode when power is applied to the unit and the power switch is on. All

lights will momentarily illuminate during the power-on self test.

Follow these steps to enter the GMA 347 Audio Panel into Configuration Mode:

1. Ensure the GMA 347 is powered off.

2. Locate connector PG11 which breaks out near connector PA28 underneath the pilot instrument

panel above the rudder pedals.

3. Plug 3-pin connector from GMA347 programming cable into PG11; plug other end into your

computer serial port.
