Operation Test For Target Tracking - JRC JMR-5410-4X Instruction Manual

Memo
• If the speed or course of the own ship is changed or a new reference target is set, the
displayed speed may take 3 minutes or more to reach the specified speed after the
speed/course change or the setting.
Even after 3 minutes or more has passed, the speed may differ from the specified speed
depending on the tracking condition.
• If the reference target is lost or the Target Tracking function is stopped, the ship speed against
the ground will be GPS. (Only if the GPS is equipped.).
• If the reference target is lost or the Target Tracking function is stopped, that will make a major
impact on the accuracy of the target tracking and the own ship speed.
• The reference targets are only used for the calculation of true speed.
• Only one target can be set as a reference target. When a new reference target is set, the
previous reference target is cancelled.

6.5.8 Operation test for target tracking

Simulation is a function for determining if the target tracking function is working
correctly or not. Accordingly, this function should be used only to check for the target
tracking function operation.
In particular, if this mode is used during navigation, a pseudo target will appear on the
radar screen and cannot be easily identified from the real target. This may cause such
an accident as collision. Do not use this mode during the navigation.
The following operation test and checking are performed to check the operation of target tracking as
required. The [TT Test] dialogue is used for operation.
[Operation procedure]
Open the Target Tracking Test dialogue by performing the following operations.
[Menu] button → Settings → TT Test
