C.1.1  Overview 
The Inter switch NQE-3141 is equipment that makes it possible to freely select several radar display 
units provided in the bridge and the several radar antennas with different properties. 
 
Even when the power supply of the display unit has been switched OFF or has become faulty, it is 
possible to operate the radar antennas from other display units. 
When it has become impossible to use the Inter switch, it is possible to carry out operations 
independently. 
The selection can be made up to a maximum of 8 units. 
When the radar antenna is switched, the following settings are read out.
