2.3 Turning the Radar On/Off
Press the [POWER] key to turn the radar on.
To turn the radar off, press the [POWER] key
together with the [STBY/TX] key.
When the radar is turned on, the control panel
lights and a timer displays the time remaining
for warm up of the magnetron (the device which
produces radar pulses), counting down from
1:30 to 0:01 (2:00 to 0:01 for FR-7252).
2.4 Transmitting
After the power is turned on and the magnetron
has warmed up, STBY (Stand-By) appears at
the screen center. This means the radar is now
fully operational.
Press the [STBY TX] key to transmit.
When transmitting, any echoes from targets
appear on the display. This radar displays ech-
oes in eight tones of green according to echo
strength.
2.5 Stand-by
When you won’t be using the radar for an ex-
tended period, but you want to keep it in a state
of readiness, place it in stand-by by pressing
the [STBY/TX] key. The display shows
“STBY,” (default setting) navigation data, or
goes into the economy mode. (You can select
stand-by condition on the menu. More on menu
operation later.)
Economy mode
The CRT can be set to automatically turn itself
off when in stand-by, to reduce power consump-
tion. This feature is called the “economy mode”.
When the economy mode is on, the
“ECONOMY” indication under the [STBY/TX]
key lights.
Navigation data display during
stand-by
If a navigation aid inputs navigation data to this
radar, navigation data can be displayed during
stand-by. You can turn the navigation data dis-
play on/off through the menu. Figure 2-3 shows
a typical navigation data display during stand-
by.
