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.
