Note: The SureSetfeature utilizes standard automotive ATC fuses to select between series or parallelvoice-coiloperation (DVC only). The fuses also providevoice-coilprotection under transient conditions such as accidental momentary overdrive. The fuses will not protect againstvoice-coilfailure resulting from long term high power abuse.
