z  When the SART function is set to ON, small targets around own ship will 
disappear from the radar display. So it is necessary to exercise full 
surveillance over the conditions around own ship by visual watch in 
order to avoid any collision or stranding. 
If two or more sets of radar equipment are installed on own ship, use 
one set of 9 GHz band radar for detection of the SART signal and 
operate others as normal radars for avoiding collision, monitoring 
targets around own ship, and checking on own ship's position and 
avoidance of stranding. 
After end of detecting the START signal, turn the START display off. 
Then the radar returns normally to the nautical mode.
