2.3 POWER ON/OFF
A malfunction may occur if the power in the ship is instantaneously
interrupted during operation of the radar. In the case, the power should be
turned on again.
Note:

Wait for about 2 seconds before turn 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.

Power on
(90 seconds preheat time is required for cold start, because of the Magnetron heater.)
After 90 seconds, anytime transmitting is possible.
Reference:
The radar cannot start transmission if you press the TX/STBY icon while the preheating time
is displayed.
