Investigators authorized by the Attorney General (hereinafter "investigators") are authorized to enter without delay and at reasonable times any establishment of a producer where records under § 75.2 are maintained to inspect during regular working hours and at other reasonable times, and within reasonable limits and in a reasonable manner, for the purpose of determining compliance with the record-keeping requirements of the Act and any other provision of the Act (hereinafter "investigator").

For the purpose of this part, "normal business hours" are from 9 a.m. to 5 p.m., local time, Monday through Friday, or, for inspections to be held at the place of business of a producer, any other time during which the producer is actually conducting business relating to producing a depiction of actual sexually explicit conduct. To the extent that the producer does not maintain at least 20 normal business hours per week, the producer must provide notice to the inspecting agency of the hours during which records will be available for inspection, which in no case may be less than 20 hours per week.

The producer or non-employee custodian or records may bring to the attention of the investigator any pertinent information regarding the records inspected or any other relevant matter.
(d) Frequency of inspections. Records may be inspected once during any four-month period, unless there is a reasonable suspicion to believe that a violation of this part has occurred, in which case an additional inspection or inspections may be conducted before the four-month period has expired.
(e) Copies of records. An investigator may copy, at no expense to the producer or to his non-employee custodian of records, during the inspection, any record that is subject to inspection.
