1. RADAR OPERATION
1.1 Turning on the Power
The [POWER] switch ( ) is located at the left corner of the control unit. Open the
POWER switch cover and press the switch to turn on the radar system. To turn
off the radar, press the switch again. The screen shows the bearing scale and
digital timer approximately 30 seconds after power-on. The
timer counts down
three minutes of warm-up time. During this period the magnetron (transmitter
tube) is warmed for transmission. When the timer has reached 0:00, the
indication “ST-BY” appears at the screen center, meaning the radar is now ready
to transmit pulses.
In the stand-by condition, markers, rings, map, charts, etc. are not shown.
Further, ARP is cancelled and the AIS display is erased.
In warm-up and stand-by condition, ON TIME and TX TIME counts in hours and
tenths of hour appear at the screen center.
Note: Avoid turning the power on directly after it has been turned off. Wait
several seconds before reapplying the power, to ensure proper start up.
1.2 Transmitter ON
After the power is turned on and the magnetron has warmed up, ST-BY appears
at the screen center, meaning the radar is ready to transmit radar pulses. You
may transmit by pressing the [STBY/TX] key on the full keyboard or roll the
trackball to choose the TX STBY box at the bottom left corner of the display and
then push the left button (above the trackball). The label at the left-hand side of
the guidance box at the bottom right corner of the screen changes from TX to
STBY.
