The address 175 404 is fixed. Jumpers: X6 all OUT, X7 IN, X8:2-4 connected.
Jumper plugs are inserted on the SHV terminals, depending on the operating mode
of the SEM (

The CD or bias voltage can be set with trimmer R4. Measure the value with a DVM
on
CD-test
. Before making any adjustments switch off the unit and remove the HV
421. One counterclockwise rotation reduces the CD voltage by approx. 150 V or
the bias voltage by approx. 80 V. Reinstall, re-measure and correct the setting, if
necessary. Do not change the settings of any other trimmers!
Up to 2 DI 420 can be installed.
