Attention
G Immediately after radar installation, after replacement of the magnetron or if the system has not
been operated for a long time, set the system to the standby mode and leave it as it is for 20 to 30
minutes before setting it to the transmit mode.
G When turning power on after power was once turned off, wait 5 min or more after setting the power
switch to OFF until setting it to ON again.
G Insufficient warming-up may cause sparks inside the magnetron and may make its oscillation unstable.
Start the transmitting mode with the short-pulse range and then go on to the long-pulse range. If the
oscillation becomes unstable during the period, immediately reset the system to the standby mode,
leave it as it is for 5 to 10 minutes and restart the system. Repeat this until the system comes to
oscillate stably.
