Garmin GPSMAP 175 - Manual (Page 51)

The proximity waypoints list lets you define an alarm circle around a
stored waypoint position, and can be used to help you avoid reefs, rocks or
restricted waters. Up to nine waypoints may be listed, with a maximum alarm
radius of 99.9 nautical or statute miles or kilometers. If a proximity alarm circle
overlaps with an existing alarm circle, a ‘Proximity Overlap’ message will
appear each time the unit is turned on. If you enter an alarm circle overlap, you
will only be alerted to the closest proximity waypoint.
To enter a proximity waypoint:
1. Highlight the ‘Proximity Waypoint’ option and press T.
2. Use the R key to highlight the first blank waypoint field and press T.

O to select the waypoint from the nearest waypoint list, waypoint list, or
map display.
4. Press T to confirm. The distance field will now be highlighted.
5. Press T to begin entry of the proximity radius.
6. Use the R keypad to enter a distance value (to 99.99 units) and press T.
To turn proximity alarms on or off:
