5.2  Starting and Shutting Down the 
Radar 
5.2.1  Powering on and starting 
 
Note 
•  Wait for about 2 seconds before turning on the power again. 
•  Immediately after the radar is installed, at start of the system after it has not been used for a 
long time, or after the magnetron is replaced, preheat the equipment in the standby state for 20 
to 30 minutes before setting it into the transmit state. 
If the preheating time is short, the magnetron causes sparks, resulting in its unstable oscillation. 
•  Start transmission on a short pulse range and change the range to the long pulse ranges in 
turn. If the transmission is unstable in the meantime, immediately place the system back into 
the standby state and maintain it in the standby state for 5 to 10 minutes before restarting the 
operation. Repeat these steps until the operation are stabilized. 
 
1  Check that the ship's mains are turned on. 
2  Press the Power button on the operation unit. 
This equipment starts and Task Menu appears on the screen.
