![xi!Use Target Tracking (TT) function only as a navigation aid. The final navigation decision must always be made by the operator him/herself. Making the final navigation decision based only on tracking target information may cause accidents.Tracking target information such as vector, target numerical data, and alarms may contain some errors. Also, targets that are not detected by the radar cannot be acquired or tracked.Making the final navigation decision based only on the radar display may cause accidents such as collisions or running aground.!A malfunction may occur if the power in the ship is instantaneously interrupted during operation of the radar. In this case, the power should be turned on again.When using the [AUTO SEA] function, never set the suppression level too high canceling out all image noises from the sea surface at close range.Detection of not only echoes from waves but also targets such as other ships or dangerous objects will become inhibited.When using the [AUTO SEA] function, make sure to choose the most appropriate image noise suppression level.When using the [AUTO RAIN] function, never set the suppression level too high canceling out all image noises from the rain or snow at close range.Detection of not only echoes from the rain or snow but also targets such as other ships or dangerous objects will become inhibited.When using the [AUTO RAIN] function, make sure to choose the most appropriate image noise suppression level.](https://usermanual.wiki/Japan-Radio/NKE1130.Users-Manual-1/User-Guide-994629-Page-13.png)

![JMA-9100 Instruction Manual > 5.OPERATION OF TARGET TRACKING AND AIS > 5.1 PREPARATION5－155.1 PREPARATION This section explains the features of the target tracking and AIS functions, and the initial setting for using each function.Target Tracking FunctionThe target tracking function calculates the course and speed of a target by automatically tracking the target's move. The target tracking function enables the automatic acquisition of targets by using the automatic acquisition zone function. The target tracking function also enables the simulation of the ship maneuvering method to avoid collisions by using the trial maneuver function.•There are the following limitations on use of the target acquisition and target tracking functions.[I] Resolution between adjacent targets and swapping during automatic target trackingDepending on the particular distance and echo size, resolution between adjacent targets during automatic target tracking usually ranges somewhere between 0.03 to 0.05 NM. If multiple targets approach each other, resolution will become about 0.05 NM and this may cause the system to regard them as one target and thus to swap them or lose part of them. Such swapping or less of targets may also occur if the picture of the target being tracked is affected by rain/snow clutter returns or sea clutter returns or moves very close to land.[II] Intensity of echoes and the target tracking functionThe intensity of echoes and the tracking function have a correlationship, and thus the target will be lost if no echoes are detected during six scans in succession. If a lost target exists, therefore, radar gain must be increased to support detection of the target. If, however, radar gain is increased too significantly, sea clutter returns or other noise may be erroneously detected and tracked as a target, and resultingly, a false alarm may be issued.[III]Adverse effects of error sources on automatic trackingTo execute accurate tracking, it becomes necessary first to appropriately adjust the [GAIN], [SEA] and [RAIN] dials of the radar so that the target to be acquired and tracked id clearly displayed on the radar display. Inappropriate settings of these adjustments reduce the reliability / accuracy of automatic tracking.Attention](https://usermanual.wiki/Japan-Radio/NKE1130.Users-Manual-1/User-Guide-994629-Page-273.png)
