If used with H-UP, the image may blur. Set the image processing (a) Select "PR1" or "PR2" in the line "PROCESS" - the menu "FUNCTION". • PR1: This is used when there is a target that is moving at low speed. Images of relatively unstable targets are emphasized and displayed in a stable manner. This function has the effect of suppressing irregular signals such as sea surface clutter. However, images of targets that are moving at high speed will become weak. As a rule of thumb, the function should be used at ranges of 1.5NM or less. 190
PR2: This function is used in stabilizing unstable images using PR1. This function is effective when sea surface clutter is abundant. As a rule of thumb, the function should be used at ranges of 3NM or more. Canceling image processing (a) Select "OFF" in the line "PROCESS" - the menu "FUNCTION". The image processing function has been canceled. 3.3.22 Moving the center of the PPI screen By moving the center of the PPI screen (relocating the center), it is possible to extend the range in any given direction. •This function is disabled when the zoom function is enabled or the maximum Range is in use. Setting the position to which the center is relocated. (a) Push the soft key DISPLAY . (b) Push the soft key 2 and select first OFF CENT and then CENTER . The marker will be displayed on PPI screen.
