2.4 Transmitting
After the power is turned on and the mag-
netron has warmed up, ST-BY (Stand-By)
appears at the screen center. This means the
radar is now fully operational. In stand-by
the radar is available for use at anytime—
but no radar waves are being transmitted.
Press the [ST-BY TX] key to transmit. When
transmitting, any echoes from targets appear
on the display. This radar displays echoes in
four tones of gray according to echo strength.
When you won’t be using the radar for an
extended period but want to keep it in a state
of readiness, press the [ST-BY TX] key to
set the radar in stand-by.
2.5 Selecting the Range
The range selected automatically determines
the range ring interval, the number of range
rings, pulselength and pulse repetition rate,
for optimal detection capability in short to
long ranges.
Procedure
Press the [– RANGE +] key. The range and
range ring interval appear at the top left cor-
ner on the display.
Tips for selecting the range
• When navigating in or around crowded
harbors, select a short range to watch for
possible collision situations.
• If you select a lower range while on open
water, increase the range occasionally to
watch for vessels that may be heading
your way.
