1. OPERATIONAL OVERVIEW

1.2 Turning the Radar On/Off, Transmitting
Press the POWER/BRILL key at the top of the control panel to turn the radar on, and the lamp to
its left lights. To turn the radar off, press and hold down the key until the screen turns black.
At power-up, the start-up screen appears, showing the model name, program number and the
results of the ROM and RAM check, OK or NG (No Good). If an NG appears, try pressing any key
other than the power key to proceed. If normal operation is not possible, contact your dealer for
advice.
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.
