DESCRIPTION Garmin has identified an issue, whereby the large (outer) BARO knob and the small (inner) CRS knob may interfere with each other.

Figure 2

IMMEDIATE ACTION REQUIRED

PFD and MFD CRS/BARO Knob Interference Test 1. Apply power to the G1000/G900X/G950. 2. Press the CDI softkey on the Primary Flight Display(s) (PFD) to enter VOR mode

on the HSI. 3. Rotate the large (outer) BARO knob (refer to Figure 2) a minimum of three

complete revolutions in each direction while monitoring the Horizontal Situation Indicator/Digital Course Indicator (refer to Figure 3) on the PFD. If a change in the Horizontal Situation Indicator/Digital Course Indicator is produced while turning the BARO knob contact your local Garmin Service Center or OEM Dealer to replace the knobs.

NOTE In some installations the Digital Course Indicator does not display unless the field is actively being edited. In these instances, if the Digital Course Indicator does not appear while turning the BARO knob, no interference is present.

4. Rotate the small (inner) CRS knob (refer to Figure 2) a minimum of three

complete revolutions in each direction while monitoring the Barometric Altimeter Setting (refer to Figure 3) on the PFD. If a change in the Barometric Altimeter Setting is produced while turning the CRS knob contact your local Garmin Service Center or OEM Dealer to replace the knobs.
