Here, hope this simplifies it:
For the survey to be valid for 7 years, the prosecution has to show/prove & submit the following:
A) When radar is used, the arresting officer has successfully completed a radar operator course of not less than 24 hours on the use of police traffic radar, and the course was approved and certified by the Commission on Peace Officer Standards and Training.
B) When laser or any other electronic device is used to measure the speed of moving objects, the arresting officer has successfully completed the training required in subparagraph (A) and an additional training course of not less than two hours approved and certified by the Commission on Peace Officer Standards and Training.
(i) The prosecution proved that the arresting officer complied with subparagraphs (A) and (B) and that an engineering and traffic survey has been conducted in accordance with subparagraph (B) of paragraph (2). The prosecution proved that, prior to the officer issuing the notice to appear, the arresting officer established that the radar, laser, or other electronic device conformed to the requirements of subparagraph (D).(D) The radar, laser, or other electronic device used to measure the speed of the accused meets or exceeds the minimal operational standards of the National Traffic Highway Safety Administration, and has been calibrated within the three years prior to the date of the alleged violation by an independent certified laser or radar repair and testing or calibration facility.
(ii) The prosecution proved the speed of the accused was unsafe for the conditions present at the time of alleged violation unless the citation was for a violation of Section 22349, 22356, or 22406.
So in other words... They have to show:
A. The officer's training certificates for an approved course on the use of Radar.
B. Doesn't apply in your case since he used Radar not Laser.
C. They have to show that:
(i) in addition to "A" and "B" as well as "D", in addition to providing a survey that was issued before five years but under 7 years of your violation date, and...
(ii) that your speed was unsafe for the conditions. &...
D. That the Radar or Laser has been calibrated within the last 3 years and that it meets the requirements in subdivision "D".
