Turning on the Power

The POWER switch is located at the left corner of the control head. Push it to switch on the
radar system. To turn off the radar, push it again. The screen shows the bearing scale and
digital timer in approximately 15 seconds after power-on. The
minutes of warm-up time. During this period the magnetron, i.e., transmitter tube, is warmed
for transmission. When the timer has reached 0:00, the indication STBY appears indicating
that the radar is now ready to transmit pulses.
In warm-up and standby condition, you will see the message BRG SIG MISSING. This is
normal because a bearing (azimuth) signal is not yet generated when the antenna is not
rotating. ON TIME and TX TIME values shown at the bottom of the screen are the time
counts in hours and tenths of hour when the radar has been powered.
