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 (device which transmits
radar pulses), counting down from 1:00 to 0:00.

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. Press the [TX] key. The radar is restored
    for full operation.

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 marker, 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.

The dialogue for adjustment of tone and
brilliance is automatically erased when there is
no TrackDisk operation for about 10 seconds. To
erase it more quickly, press the [TONE] key after
making the adjustment.

The range selected automatically determines the
range ring interval, the number of range rings
and pulse repetition rate.

Press the [+] or [-] key to select a range. The
range and range ring interval appear at the top
left corner on the screen.
