Turning the Radar On/Off, Transmitting
Press the
POWER/BRILL
key at the upper right-hand corner of the control panel to turn on the
radar on. Press and hold down the key until the screen turns black to turn the radar off.
At power-up the start-up screen appears as shown right. The model name and program number
are shown and the ROM and RAM are tested. If "NG" appears as the results of the ROM and RAM
tests, try pressing any key to proceed. If normal operation is not possible, contact your dealer for
advice. 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 90 sec. (FR-8252) or 180 sec. (FR-8062, FR-8122).
Start-up screen
After the timer has counted down to 0:00, the indication STBY appears at the screen center,
meaning 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 for an extended period of time. This
will help 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.
