WARNING! Ensure power is off during installation. Use appropriate marine-grade wiring.

First-Time Setup

Power on unit; allow time for satellite acquisition.

1. Initialize: On first use, unit may need several minutes to acquire satellites.
2. Set position format: Access SETUP menu, select preferred format (e.g., hddd°mm.mmm').
3. Set datum: Match datum to your charts (WGS 84 default).
4. Set units: Select nautical miles/knots, statute miles/mph, or kilometers/kmh.
5. Set time: Adjust to local time zone and daylight saving if needed.

CAUTION! Ensure secure mounting before operation in moving vessel.
