Service and Repair of Type 5128
HF HATS Type 5128 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 HF 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.
