Radar
5.2.1

Powering on and starting

Memo
• 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 long 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 stabilised.
• Even if the Standby/Transmit switch button is clicked on while "Preheat" is being displayed,
radar transmission cannot be performed.
