Failure to establish all of foundation elements.

- When the defendant was convicted of speeding, the defendant was correct that the state failed to establish all of the foundational elements that are applicable to state troopers, such as the introduction of evidence as to the State Patrol's licensing and annual certification of its radar devices. Brown v. State, 204 Ga. App. 629, 420 S.E.2d 35 (1992), overruled on other grounds, Carver v. State, 208 Ga. App. 405, 430 S.E.2d 790 (1993).

Defendant waived claim of error regarding proper foundation.

- Defendant did not show that the trial court erred in admitting into evidence the results of a radar speed detection device as the defendant objected to admission of the results for lack of "foundation," but did not state what the foundation should be; accordingly, the defendant waived a claim of error. Keller v. State, 271 Ga. App. 79, 608 S.E.2d 697 (2004).

Certificate of accuracy dated within one year prior to the use of radar.

- State met the requirements of the statute by producing a copy of the certificate of accuracy dated within one year prior to the use of the radar in the case. Gamble v. State, 237 Ga. App. 414, 515 S.E.2d 422 (1999).

Administrative certificate sufficient for county police.

- When a radar detection device was operated by a county officer, the administrative permit issued by the Department of Public Safety presumptively complied with O.C.G.A. § 40-14-4 and an actual Federal Communications Commission license did not need to be produced to demonstrate compliance. Brooker v. State, 206 Ga. App. 563, 426 S.E.2d 39 (1992); Nairon v. State, 215 Ga. App. 76, 449 S.E.2d 634 (1994).

Uncertified technician.

- When the manufacturer's certification of accuracy and correctness of operation failed to show that the compliance check was done by a technician possessing certification as required by the Department of Public Safety, the state failed to show compliance with the third foundational requirement contained in Wiggins, and the admission of the radar evidence of speed was error. Hardaway v. State, 207 Ga. App. 150, 427 S.E.2d 527 (1993).
