Mississauga Toronto Ontario lawyer Stephen R. Biss speaks about the effect of cell phones on the reliability of the evidentiary breath instruments used in Ontario Canada. Radio frequency interference from a transmitting Nokia 3500 cell phone causes an apparent blood alcohol concentration beyond 700 mg/100mls on an Intoxilyzer 5000 64 series product number 564 CA model similar to the Intoxilyzer 5000C used peviously by police in Ontario Canada. Police in Ontario now use the Intoxilyzer 8000C.
