Start-up screen

After the tests are completed, the bearing scale and a digital timer appear. The digital timer counts down the time remaining to warm up the magnetron, which transmits the radar pulses. This warm- up takes 180 sec. (FR-8252) or 90 sec. (FR-8062, FR-8122).

After the timer has counted down to 0:00, the STBY screen appears, the appearance of which you may choose according to your needs. (For further details, see paragraph 1.41.2.) The radar is now ready to transmit radar pulses. Press the STBY/TX key to transmit radar pulses.

The STBY/TX key toggles between stand-by and transmit status. The antenna rotates in transmit condition and is stopped in standby. Because the magnetron ages with use it is highly recom- mended to set the radar in standby when it will not be required, to extend the life of the magnetron.

Quick start

Provided that the radar was once in use with the transmitter tube (magnetron) still warm, you can get the radar into TRANSMIT condition without the warm-up. If the POWER/BRILL key was turned off by mistake or the like and you wish to restart the radar promptly, turn on the POWER/ BRILL key not later than 10 seconds after power-off. This feature is not available with the

FR-8252.
