There is a timer that counts the number of hours the magnetron has been transmitting. The
system gives a warning when the magnetron is close to the end of its expected lifetime.
From the radar data dialog, it is possible to view the hour count and the magnetron end of life
status (which reports OK or FAIL). When the magnetron is replaced, the timer should be reset.
Access the Installation dialog, and select the Magnetron timers reset option.
