Perform a tuning fork test
Place the BEE III into stationary mode by pressing the Mov/Sta button on the
remote. Turn the transmitter on to the front antenna by pressing the raised Front
button. Place a ringing fork in front of the antenna. The radar will read the speed
marked on the tuning fork, within one mile per hour, in its red Target speed
display. 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.
Alternately, you may place the radar into Tuning fork mode to perform the test,
as is detailed on page 24 of this manual.
Notice again that the radar gives two indications that it is operating in stationary
mode. Firstly, the Sta icon under the middle speed window is lighted. Secondly,
the Patrol window is filled with dashes, indicating that the radar will not pick up a
patrol speed. When you are in moving mode, the Mov icon under the middle
speed window is lighted, and there are no dashes in the Patrol window.
Try locking in a speed.
This is a good time to try the lock function. Place a ringing fork in front of the
antenna again. While the readout is displaying a speed in the Target window,
press the remote’s Lock button. Note that the tuning fork’s speed is locked in
the middle window. Also, the T-lock icon, which is located directly under the
BEE III's middle window is lighted, designating that the speed in the middle
window is a locked target speed.
Every time that the lock button is pressed, the radar will transfer the speed in the
Target window over to the middle window. Also, if you place the radar into
Standby, the operating mode at the time the speed was locked will be displayed in
the Mode window.
To clear a locked speed, press either the Front or Rear antenna button. This will
clear the locked speed regardless of whether or not there is a target speed
displayed in the Target window.
Locked speeds are also erased in other ways. If the radar is placed into Standby,
the locked speed is preserved, but if the BEE III is then made to transmit again,
the locked speed is cleared. (This is an IACP requirement.) Also, locked speeds
are automatically cleared 15 minutes after they are locked to preserve the
