i SAFETY INSTRUCTIONS WARNING Radio Frequency Radiation Hazard The radar antenna emits electromagnetic radio frequency (RF) energy which can be harmful, particularly to your eyes. Never look directly into the antenna aperture from a close distance while the radar is in operation or expose yourself to the transmitting antenna at a close distance. Di[...]

ii WARNING Do not place liquid-filled containers on the top of the equipment. Fire or electrical shock can result if a liquid spills into the equipment. Do not operate the equipment with wet hands. Electrical shock can result. Keep heater away from equipment. Heat can alter equipment shape and melt the power cord, which can cause fire or electrical[...]

iii CAUTION The plotting accuracy and response of this auto plotter meets IMO standards. Tracking accuracy is affected by the following: • Tracking accuracy is affected by course change. One to two minutes is required to restore vectors to full accuracy after an abrupt course change. (The actual amount depends on gyrocompass specifications.) • [...]

iv Safety Instructions for VIDEO PLOTTER RP-26 (Option) CAUTION No one navigational aid should be relied upon for the safety of vessel and crew. The navigator has the responsi- bility to check all aids available to confirm position. Electronic aids are not a substitute for basic navigational principles and common sense. ❐ Digital charts cannot re[...]

1-14 2. T o enable selection of S2 (0.15 m s) and M1 (0.3 m s) pulsewidth on the 3 SM range, select S2 at 3 SM in the PULSE WD 1 menu and M1 at 3 SM in the PULSE WD 2 menu. A longer pulse provides an increased detection range, but with reduced discrimination. If you need discrimination in preference to detection, choose a shorter pulse. Example: T [...]

1-15 1.13 Adjusting the Sensitivity The [GAIN] control is used to adjust the sensitivity of the receiver , and thus the intensity of echoes as they appear on the screen. It should be adjusted so that the speckled back- ground noise is just visible on the screen. T o become acquainted with the way the [GAIN] control works, try rotating it between fu[...]

It is mainly dependent on the pulselength, antenna[...]

2-2 X-band and S-band In fair weather , the above equation does not give a significant difference between X- and S-band radars.

2-5 2.3 SART (Search and Rescue T ransponder) A Search and Rescue T ransponder (SAR T) may be triggered by any X-Band (3 cm) radar within a range of approximately 8 nm.

5-28 Indirect echoes A target at close range is usually picked up directly , but it can also be received as reflec- tion from a large, flat surface. This will result in the radar presenting two or more echoes on the display , each at a different range. The ARP A can acquire and track the false echo if it is detected by five consecutive scans.
