1.1 Turning on the Power
DANGER
Before turning on the radar, make sure
no one is near the antenna unit.
Serious injury or death may result if a
rotating antenna strikes someone standing
nearby.
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 timer counts down
three 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 the radar is now ready to transmit pulses.

Note: Allow 10 seconds to elapse before turning off the power, to permit writing of
settings.
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 the radar has been powered.
