Select VLOC on CDI for approach - The aircraft is inbound and within 3 nm of the FAF; and the active approach is not a GPS-approved approach. Verify that the VLOC receiver is tuned to the proper frequency and press the CDI Key to display ‘VLOC’ (directly above the CDI Key).

Set course to [###]° - The course select for the external CDI (or HSI) should be set to the specified course. The message only occurs when the current selected course is greater than 10° different from the desired track.

Steep turn ahead - This message appears approximately one minute prior to a turn in one of the following three conditions: 1) the turn requires a bank angle in excess of 25° in order to stay on course, 2) the turn requires a course change greater than 175°, or 3) during a DME arc approach the turn anticipation distance exceeds 90 seconds.

Stored data was lost - All user waypoints, flight plans, and system settings have been lost due to a memory battery failure or system reset.

Terrain - See Section 12.3 and 13.3 for complete lists of TAWS and TERRAIN related Alerts and Annunciations.

Terrain configuration conflict - The hardware configuration does not match the terrain software configuration. The operational status of the terrain components is unknown and the unit should be returned to a Garmin dealer for service.

Terrain configuration has changed - The software has detected a change in the terrain configuration.

Terrain has failed - The terrain functionality self-test has failed. The operational status of the terrain components is unknown and the unit

should be returned to a Garmin dealer for service.

Timer has expired - The count down timer has reached zero.

Traffic device needs service - Either the TCAD battery or the TCAD interrogation device has failed. If the message persists, contact a Garmin dealer for assistance.

Unit configuration has changed - The GNS

530 has detected a failure (during initial power up) in its system configuration. Some system components may be unusable. Try cycling power off and back on. If the message persists, contact a Garmin dealer for assistance.

User card format unknown - A data card has been inserted, but the format of the card is not recognized.

VLOC has failed - The GNS 530 has detected a failure in its VLOC receiver. The VLOC receiver is not available and the unit should be returned to a Garmin dealer for service.

VLOC is not responding - Internal system- to-system communication between the main processor and the VLOC receiver has failed. Operational status of the VLOC receiver is unknown and the unit should be returned to a Garmin dealer for service.

VLOC needs service - The GNS 530 has detected a failure in its VLOC receiver. The VLOC receiver may still be usable, but the unit should be returned (at the earliest convenience) to a Garmin dealer for service.

VLOC remote transfer key is stuck - The remote VLOC transfer switch is stuck in the enabled (or pressed) state. Try pressing the switch again to cycle its operation. If the message
