transient (caused by lightning or switching surge to the system) by accident or
abnormal conditions of operation, the series fusible resistors will be blown open
(become high impedance) like fuses to protect the user and the instrument.

series fusible resistors and the spark gaps should then be replaced by qualified
technician. Refer to the LIMITED WARRANTY section for obtaining warranty or
