Note: When the length of the cable between the scanner unit and the power
supply unit is more than 60 meters, the magnetron heater voltage may not reach
the lower limit due to voltage drop. If this is the case, increase the voltage with the
sliding contact R813 in the power supply unit, and readjust with R811, R812 in
the scanner unit.
