OPERATIONAL OVERVIEW

1.1 Turning on the Power

The [POWER] switch is located at the top left corner of the display unit. Push it to switch on the radar set. To turn off the radar, push it again. The screen shows the bearing scale and digital timer approximately 15 seconds after power-on. The timer counts down three minutes of warm-up time. During this period the magnetron, that is, the transmitter tube, is warmed for transmission. When the timer has reached 0:00, the indication STBY ap- pears, indicating that the radar is now ready to transmit pulses.

DANGER

Before turning on the radar, make sure that there is no one near the antenna.

Serious injury or even death may result if

a rotating antenna strikes someone standing nearby.

1.2 Transmitter ON

After the power has been turned on and the magnetron has warmed, STBY (Standby) ap- pears at the screen center, indicating the ra- dar is ready to transmit radar pulses.

Press the [STBY/TX] key to transmit.

When you won’t be using the radar for an extended period, but you want to keep it in a state of readiness, place it in standby by pressing the [STBY/TX] key. The display shows STBY when the radar is in standby.

Video Lockup Recovery

Video freeze-up or lock-up, can occur unex- pectedly on digital rasterscan radars. This is mainly caused by heavy spike noise in the power line and can be noticed by carefully watching the nearly invisible sweep line.

If you suspect that the picture is not updated every scan of the antenna or no key entry is accepted notwithstanding the apparently normal picture, do Quick Start to restore normal operation.

1.Turn off the POWER switch and turn it on again within 10 seconds.

2.Push the Transmit switch labeled STBY/TX for Transmit status.
