Follow the instructions be-low if a battery is used. Tape the + and - terminals of battery before disposal to prevent fire, heat generation caused by short circuit.In the European UnionThe crossed-out trash can symbol indicates that all types of batteries must not be discarded in standard trash, or at a trash site. Take the used batter-ies to a battery collection site according to your national legislation and the Batteries Directive 2006/66/EU. In the USAThe Mobius loop symbol (three chasing arrows) indicates that Ni-Cd and lead-acid rechargeable batteries must be recycled. Take the used batteries to a battery collection site according to local laws.In the other countriesThere are no international standards for the battery recycle symbol. The number of symbols can increase when the other countries make their own recycle symbols in the future.•  This manual has been authored with simplified grammar, to meet the needs of international users.•  The operator of this equipment must read and follow the descriptions in this manual.

ii SAFETY INSTRUCTIONS Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. Indicates a potentially hazardous situation which, if not avoided, could result in minor or moderate injury. The operator must read the safety instructions before attempting to operate the equipment.Warning, Caution Prohibitive Action Mandatory ActionWARNINGCAUTIONWARNINGDo not open the equipment.The equipment uses high voltage that can cause electrical shock. Refer any repair work to a qualified technician.Before turning on the radar, be sure no one is near the antenna.Prevent the potential risk of being struck by the rotating antenna, which can result in serious injury or death.If water leaks into the equipment or something is dropped into the equipment, immediately turn off the power at the switchboard.Fire or electrical shock can result.If the equipment is giving off smoke or fire, immediately turn off the power at the switchboard.Fire or electrical shock can result.If you feel the equipment is acting abnormally or giving off strange noises, immediately turn off the power at the switchboard and contact a service technician.Do not disassemble or modify the equipment.Fire, electrical shock or serious injury can result.Make sure no rain or water splash leaks into the equipment.Fire or electrical shock can result if water leaks into the equipment.Do not place liquid-filled containers on or near 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 objects away from the antenna unit, so as not to impede rotation of the antenna.Fire, electrical shock or serious injury can result.Use the proper fuse. Use of the wrong fuse can cause fire or electrical shock.The data from AIS are intended for reference purposes only.Check all available navigation aids to determine target movement.Do not depend on one navigation device for the navigation of the ship. The navigator must check all aids available to confirm position.-  The TT (Target Tracking) automatically tracks an automatically or manually acquired radar target and calculates its course and speed, indicating them with a vector. Since the data generated by the TT depends on the selected radar targets, the radar must be optimally tuned for use with the TT, to ensure required targets will not be lost or unnecessary targets like sea returns and noise will not be acquired and tracked.-  A target is not always a landmass, reef, ship, but can also be returns from the sea surface and from clutter. As the level of clutter changes with the environment, the operator must correctly adjust the sea and rain clutter controls and the gain control so that the target echoes do not disappear from the radar screen.WARNING WARNINGCAUTION
SAFETY INSTRUCTIONSiiiThe TT tracks and plots the movement of up to 100 radar targets and fully complieswith IMO standards for TT.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.)- Echo intensity - Radar transmission pulse width - Radar bearing error - Gyrocompass error - Course change (own ship and target)▪ The amount of tracking delay is inversely proportional to the relative speed of the target. Delay is approx. 15-30 seconds for the higher relative speed; approx. 30-60 seconds for the lower relative speed. The following factors can affect accuracy:The data generated by TT and AIS are intended for reference only.Refer to official nautical charts for detailed and up-to-date information.CAUTION

The target pips are painted at their measured distances and in their directions relative to own ship's             heading.The short line on the bearing scale is the north marker, which indicates heading     sensor north.•  HEAD UP (TB)Radar echoes are shown in the same way as in the head-up mode. The difference from normal head-up presentation lies in the orientation of the bearing scale. The bearing scale rotates in accordance with the heading sensor signal, enabling you to know own ship's heading at a glance.This mode is available when the radar is interfaced with a gyro heading sensor. If the gyro heading sensor fails, the bearing scale returns to the state of head-up mode.•  STERN UPA display without azimuth stabilization in which the line that connects the center with the top of the display indicates your stern.•  NORTH UPThe north-up mode paints target pips at their measured distances and in their true (heading sensor) directions from own ship, north bearing is fixed at the top of the screen. The heading line changes its direction according to the ship's heading. This mode requires heading signal.If the compass fails, the orientation mode changes to head-up and the north marker     disappears.•  COURSE UPThe course-up mode is an azimuth stabilized display in which a line connecting the center with the top of the display indicates own ship's intended course (namely, own ship's previous heading just before this mode has been           selected).Target pips are painted at their    measured distances and in their directions    relative to the intended course, which is     maintained at the 0-degree position.                The heading line moves in accordance with ship's yawing and course change.North marker Heading lineNorth markHeading lineNorth mark Heading line
