2.3 POWER ON/OFF

2.3 POWER ON/OFF
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.
Note:
 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.
 Power On
