When the radar is switched to TX (transmit) status, most settings (such as brilliance,
range, pulse width, etc) are restored with the same settings as before standby.
For magnetron radars, it is recommended to place the radar in standby when trans-
mission is not required, to reduce wear on the magnetron. You can also set a "blank
sector" where transmission is stopped (see the Installation Manual for details).
How to stop antenna rotation
Antenna rotation can be stopped using one of the following procedures:
• Turn the antenna switch off.
• Turn antenna rotation off from the menu (See installation manual).
Screen freeze
The screen is not refreshed if the screen has frozen. An audio alarm is released 30
seconds after a screen freeze. The ALARM ACK key flashes and a contact alert sig-
nal is also released. To return the radar to normal operation, turn the radar off, then
on again.
Quick start
Provided that the radar was in use and the magnetron (transmitter tube) is still warm,
you can switch to transmit mode without the three minute warm-up time. If the radar
was turned off by mistake or you wish to restart the radar promptly, wait several sec-
onds before you press the POWER switch.
