1.1 General

Congratulations on selecting the Autohelm ST50 LCD Radar for your
radar navigation needs.
Whether you purchased this radar because of its compactness, power
economy, ease of installation, or long term reliability, one thing is
certain; the moment you turn on your ST50 Display you will know you
are seeing a revolutionary new concept in radar technology at work.
You are the proud owner of a radar system unmatched within the
recreational marine industry.
Radar signals are "stored" on an LCD display with chart like clarity and
detail. A single glance at your Display will give you's complete and
accurate 360' radar picture of other vessels, buoys and landfall
surrounding your vessel.
The l/8 NM range scale together with the Offset mode makes
navigating tight channels, rivers, or waterways at night a pleasure
instead of a problem.
The Zoom mode gives you a fast 2 times enlargement of the radar
presentation in the zone you have designated. "Timed TX" mode lets
the radar automatically turn its transmitter "on" and "off" for scans of
the area around your vessel to save battery power. Set the target
alarm zone to alert you of any radar contacts that have entered your
zone, including any that might have escaped your notice.
Electronic Bearing Line (EBL), Variable Range Marker (VRMIand cursor
allow rapid high accuracy target bearing and range measurements.
When connected to a GPS or Loran Navigator with proper output data
format for full function operation, the radar can display your destination
destination, and can be used to help locate specific buoys or waypoint
landmarks.
