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. Distances at which RF radiation levels of 100 and 10 W/m2 exist are given in the table below. [. . . ] With the cursor inside the effective display area, roll the wheel to display "REF MARK / EXIT" in the guidance box. Select a small fixed island or any radar prominent point located at 0. 2 to 24 nm from own ship. Roll the trackball to place the cursor (+) on the target selected at step 2. 3-3 3. Push the left button to enter the reference mark. (The mark may also be entered by pressing the [ENTER MARK] key on the full keyboard. ) The reference target mark (see below) appears at the cursor position and the own ship position data label changes from "LOG, " "NAV" or "MANUAL" to "REF. " Note that it takes 60 scans or approximately 1 min before a new speed is displayed. If tracking has failed for a reference target, the target is marked with a lost target mark (symbol formed with two triangles). R1 changes to R1 in 60 seconds. Reference target 5. Repeat steps 2-4 to continue entering reference marks. Notes on speed input by reference target · When the reference target is lost or goes out of the acquisition range, the reference target mark blinks and the speed reads "**. *. " Select a different reference target in this case. · When all targets are deleted, the reference target mark is also deleted and the target-based speed becomes invalid. The speed is indicated as KTBT where BT means Bottom Track (speed over ground). · Reference targets may be marked with a vector. This can be done with 3 REF TARGET VECTOR on the ARP TARGET menu. Canceling echo-referenced speed input Open the SPD menu, referring to paragraph 1. 13, and set 1 SHIP SPEED to LOG, NAV or MANUAL as appropriate. 3-4 3. ARP OPERATION 3. 5 Automatic Acquisition The FAR-2xx7 radars can acquire a maximum of 100 targets, the number of automatically and manually acquired targets determined by the ARP TGT menu setting.

Within 60 scans (20 scans for HSC), the initial tracking stage is finished and the target becomes ready for stable tracking. At this point, the broken square mark changes to a solid circle. (Targets automatically acquired are distinguished from those acquired manually. The targets which are acquired manually are displayed by bold symbol. ) 3. 5. 1 Enabling auto acquisition 1.
