OPERATION
2.1

How to Transmit

After the power is turned on and the magnetron has
warmed*, "ST-BY" appears at the screen center, meaning
the radar is ready to transmit radar pulses. You can transmit
by pushing the STBY/TX key on the Control Unit, or clicking
the [STBY TX] button on the Status bar.
*: The solid state radar does not have a magnetron, therefore it has no warming peri-
od.
The radar is initially set to previously used range and pulse length. Other settings such
as brilliance levels, VRMs, EBLs and menu option selections are also set to previous
settings.
The STBY/TX key (or [STBY TX] button) toggles the radar between STBY and
TRANSMIT state. The antenna is stopped in stand-by and rotates in transmit. Set the
radar in standby when its use is not required, to conserve the life of the magnetron.

How to Tune the Radar Receiver

After the radar is transmitting, adjust the receiver to the exact frequency of the trans-
mitter.
