2.2 Turning the Radar On/Off

Press the [POWER] key to turn the radar on or off.

The control panel lights and a timer displays the time remaining for warm up of the mag- netron (the device which produces radar pulses), counting down from 1:30 to 0:01.

2.4 Stand-by

When you won’t be using the radar for an extended 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,” navigation data, or goes into the economy mode depending on menu set- ting. (More on menu operation later.)

2.3 Transmitting

After the power is turned on and the magne- tron has warmed up, STBY (Stand-By) ap- pears 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 echoes in eight tones of green according to echo strength.

Economy mode

The CRT can be set to automatically turn it- self off when in stand-by, to reduce power consumption. This feature is called the “economy mode.” Power consumption in the economy mode is 28 W. When the economy mode is on, the lamp next to the [POWER] key lights.

Navigation data display during stand-by

If a navigation aid inputs navigation data to this radar in IEC 61162 format, navigation data can be displayed during stand-by. You can turn the navigation data display on/off through the menu. Figure 2-2 shows a typi- cal navigation data display during stand-by.
