3.1.1 Power ON and Start the System
!
• A malfunction may occur if the power in the ship is
instantaneously interrupted during operation of the
radar. In this case, the power should be turned on
again.
• 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 longer 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 is stabilized.
