1.7.2 Warming Up
It has to be noted that at start-up the Radar needs a variable time from 90 to 120
seconds to heat up the magnetron (microwave emitting tube). During this time it
is not possible to turn on the transmission.
Radar pages are visible but with a small overlapping message window showing
the time remaining to Warm Up completion:
"Radar Warming Up! xx seconds remaining!"
At completion of the Warm Up sequence the following message will be displayed:
"Radar Warming Up! Warm Up Completed!"
This window shall remain open for 2 seconds, then it will close automatically.
At this point the Radar is ready for operation. Transmission is turned Off and
"STAND BY" message is displayed at the center of the Radar page.

SWR 9/SWR 10
When the Radar is turned Off, the antenna comes to a stop. If you want to have
the antenna to stop in a specific position, the Antenna Parking Position function
can be used to choose the desired antenna position. This function only controls
the antenna position at which the power to the motor is cut off. The distance
through which it comes to a stop from this point depends on temperature and
