integrity of the evidence. The automatic clearing is preceded by a 30 second

countdown if the BEE is in Standby to inform the officer of the imminent

clearing of the display so the officer can record the speed before it is erased.

A double click of the lock button will also clear the lock window.

Perform moving mode tuning fork tests

Place the BEE III into moving mode by pressing the Mov/Sta button on the

remote. If the radar is not in opposite direction moving mode, press the

Opposite button. Turn the transmitter on to the front antenna by pressing the

raised Front button. Strike the lower frequency fork on a hard nonmetallic

surface and hold the ringing fork in a fixed position two or three inches in front

of the antenna with the narrow edge of the fork facing the antenna. The speed

will be shown in the patrol window. You may have to move the tuning fork gently

toward and away from the antenna in order to get the radar to read it properly.

This is because a tuning fork vibrates both toward and away from the radar, and

the radar is expecting to see a target moving either toward it or away from it, but

not both directions at once. While continuing to hold the ringing fork in place,

strike the other fork and hold it next to the patrol speed fork. Both forks must be

vibrating while being held an equal distance from the antenna. The radar should

display the difference between the forks as the target speed. For example, for

forks marked 35 mph and 65 mph, the patrol would read 35 (low speed fork) and

the target would read 30 (high-speed fork minus low speed fork).
