After installing my new RADAR, I noticed that the
indicated bearing to a target does not agree with the actual bearing. How
do I correct this?
All Raytheon RADARS require a bearing alignment procedure during initial
setup. Please refer to your owner's manual for a description of the setup
procedure or to an authorised technician.

I have a GPS receiver interfaced with my Raytheon
RADAR. When navigating to a waypoint, why does the waypoint identifier
jump around on the screen?
This condition occurs because the RADAR is using course over ground
(COG) information from the GPS to determine the ship's heading. COG is
an "average heading" calculated over time, and may not update with the
"real time" image on the RADAR screen. This can be corrected on the XX
series, RL9, and Autohelm ST50 RADARS with the addition of an electronic
fluxgate compass which delivers "real time" heading information. This will
stabilise the waypoint symbol on the RADAR screen. Raytheon offers the
optional XX heading sensor (fluxgate compass) or the RADARS will also accept
heading information from a Raytheon or Autohelm Autopilot via the Seatalk
interface. (Seatalk is optional on the RL9, R10XX. and R11XX.)

In my marina I notice that my pathfinder radar does
not show many targets on short ranges.
This is probably due to the fact that in a marina or harbour situation
you may need to switch STC and GAIN to manual and adjust them as necessary.
The STC will need to be lowered to improve the target detection.

I am concerned that my radar may be harmful when
transmitting and people are on the flybridge close to the radar beam.
Due to the relatively low power of leisure radars this is generally
not considered to be a problem, as long as people are a few feet from the
scanner unit.

Can I interface my Raytheon radar with my GPS?
All Raytheon radars can be interfaced via NMEA to a GPS, and most can
accept Seatalk GPS without the need for any kind of interface box.
