z Wait for about 2 seconds before turning on the
power again.
z 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.
z 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 are stabilized.
CAUTION
3.1.1 Power ON and Start the System
Attention
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.
