Warning: Radio frequency radiation hazard
The radar scanner transmits electromagnetic energy at microwave frequencies
which can be harmful, particularly to the eyes. Do NOT look at the scanner from
close range. Ensure personnel are clear of the scanner when it is powered on.
For safety reasons, the radar must be installed above head height, out of range
of personnel.
Caution: Service and maintenance
This product contains no user serviceable components. Please refer all
maintenance and repair to authorized Raymarine dealers. Unauthorized repair
may affect your warranty.
Caution: Doppler “wagon-wheeling” effect
• There are limits to the maximum relative speed that the radar scanner can
measure when processing Doppler targets. When the target is moving at
high speeds these limits can result in a stroboscopic visual effect known as
“wagon-wheeling” or “aliasing”.
• “Wagon-wheeling” refers to an optical illusion similar to that seen in some
movies, where wagon wheels appear to occasionally rotate backwards. When
using Doppler radar the effect occurs when the target is moving fast and the
frequency of the transmit pulses, when the target is illuminated by the radar,
is insufficient to distinguish whether the target is moving towards or away
from the vessel.
• The result of this visual effect is that the direction of target returns from high
speed vessels may be displayed incorrectly. Consequently, the displayed
target colors may be inverted, with targets colored red when they should be
green, and vice versa:
– When the target's speed is more than 60 knots Speed Over Ground (SOG),
or the relative speed between your vessel and the target is greater than 120
knots, the target colors may be inverted as follows:
♦ Approaching objects are highlighted in green.
♦ Receding objects are highlighted in red.
