Service and Repair of Type 4128-C
Head and Torso Simulator Type 4128-C has been designed to provide many years of reliable
operation and under normal use there should be no significant deviation from the stated
specifications. However, if a fault occurs, disconnect the HATS from all external instruments
and consult your local Brüel &Kjær service representative. Under no circumstances should
repair be attempted by persons not qualified in the service of electronic instrumentation.
