2. OPERATION
2.1 Turning the Radar On/Off
The [POWER] key turns the radar on/off. When
turning on the power, the control panel lights
and the timer displays the time remaining for
warm up of the magnetron (the device which
transmits radar pulses), counting down from
1:00 to 0:00.
Quick Start
Provided that the radar was once in use with
the transmitter tube (magnetron) still warm,
you can turn on the radar into TRANSMIT
status without the one-minute stand-by.
If the power switch has been turned off by
mistake and you want to restart the radar
promptly do the following:
1. Press the [POWER] key not later than five
seconds after power-off.
2. After ST-BY appears, press the [TX] key.
The radar is restored for full operation.
2.2 Transmitting, Stand-by
After the power is turned on and the magnetron
has warmed up, ST-BY (Stand-By) appears at
the screen center, indicating the radar is ready
to transmit radar pulses.
Press the [TX] key to transmit. Echoes appear
in four levels of digitized video according to
echo strength. Note that when a target is
beneath a marker (VRM, EBL, heading line and
range ring) the part of the marker where the
target lies is displayed in reverse video.
Note: If you press the [TX] key before the
indication ST-BY appears, the buzzer sounds
and the radar does not transmit pulses.
When you won’t be using the radar for an
extended period, but you want to keep it in a
state of readiness, press the [TX] key to set the
radar in stand-by. It is recommended to set the
radar in stand-by when it is not in use to extend
the life of the magnetron.
