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, TT and AIS are not shown.
In the warm-up and stand-by conditions, ON TIME and TX TIME count in hours
and tenths of hour appear at the screen center.
Note 1:
Do not turn the power on directly after it has been turned off. Wait
several seconds before you reapply the power, to be sure the radar
starts up properly.
Note 2:
Parameters set on the menus are stored in a non-volatile memory (flash
memory), and are preserved when the power is turned off.
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 use the
trackball to select the TX STBY box at the bottom left corner of the display 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.
