Power ON and Start the System･･･････････････････････････
Attention
Wait approximately 10 seconds before turning on the power again.
A malfunction may occur if the power in the ship is suddenly interrupted during
operation of the radar. In this case, the power should be turned on again.
Immediately after the radar is installed, if the system is not used for a long time,
３
or after the magnetron is replaced, warm-up the equipment in the standby mode
for 20 to 30 minutes before setting it to the transmit mode.
If the warm-up time is short, the magnetron may cause sparks, resulting in an
unstable oscillation.
Start transmission on a short-pulse range and then send long pulses
sequentially. If the transmission is unstable in the meantime, reset the system
to the standby mode immediately and maintain it in the standby mode for 5 to 10
minutes before restarting the operation. Repeat these steps until the operation
is stabilized.
