Turning on the radar

Press the POWER key. The control panel lights and a timer displays the time remaining for warm up of the magnetron, counting down from 3:00 to 0:00.

Turning off the radar

Press POWER and ST BY/TX keys together.

1.2 Transmitting, Stand-by

Transmitting

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. In stand-by the radar is available for use at any time.

Press the ST BY/TX key to transmit. The radar displays echoes in eight intensities according to echo strength.

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 ST BY/TX key. The display shows ST-BY.
