Introduction MPH Industries, Inc. designed the BEE III Doppler radar with the police offic er in mind. The radar is easy to operate and includes the performance and features needed for today's traffic environment. The BEE III is the most useful and flexible radar available; it is a full -featured moving radar with fastest and same direction cap ability. The BEE III utilizes MPH’s patented Automatic Same Direction ™ (ASD™ ) technology.
A Detailed Explanation of the BEE III's Features Practical use of the BEE III The BEE III allows the operator to choose various types of use and operation. The radar may be used as a conventional MOVING, STATIONARY, or PACING radar. The BEE III also feat ures the SAME DIRECTION MOVING and FASTEST features. Each of these uses is described below. Stationary radar As a stationary radar, the MPH BEE III allows the officer to monitor traffic coming or going while the patrol vehicle is stopped.
Modern DSP radar such as the BEE III can process many targets at the same time, but there is no practical way to display multiple targets and associate them with the corr ect vehicles. Fastest mode gives the operator an opportunity to view one other target besides the strongest. In this mode, the BEE III considers all possible targets (there may be several in range of the radar) and displays the fastest one. Doppler audi o is also provided for this target.
Display The BEE III uses a high contrast LED display with automatic dimming. Mode The mode section shows what the radar is doing. The display is set up like a roadway. A large red “X” icon in th e left lane tells at a glance that the transmitter is in standby. A large green car in the right line indicates that the transmitter is on. The operating mode of the BEE III is illustrated with the scene of a patrol car and selected targets.
Speed windows The BEE III has three windows for speed display. These are arranged by function and use color for quick identification at night. The leftmost display is a dedicated red target window. This window always displays the strongest target’s speed, even in fastest mode. Error conditions such as radio frequency interference (rFi), low voltage (Lo), and general sy stem errors (Err) are also displayed in this window.
Remote Control The remote is a battery -powered infrared remote control, much like one for a television. There is no action required to turn power on or off on the remote, but try to avoid storing the remote with any switch depressed in order to avoid draining its batteries. The BEE III has two main sections of controls located on its face. These sections are separated by a heavy white line on the label.
Less-frequently used keys. These keys are flat membrane -type keys which are embossed around their edges to make them easy to identify by feel. Some of the keys have two colors of text identifying them. The red text is the default function of the key; pressing the key by itself will cause it to perform this function. The function in blue text is initiated by first pressing the blue “2ndF” key. Mov/Sta – Toggles the radar between moving and stationary operating mode s.
Menu No presses of the menu button – Adjust the audio volume Audio volume has 7 settings (including mute). During volume ad justment, “A” is displayed in the middle window of the radar, followed by the current setting. On its initial power -up, the volume is initially set to level 3. On subsequent power -ups, the BEE III retains the volume setting it had when the radar was turn ed off. Pressing the “— “ key lowers the volume one level; pressing the “ +” raises the volume.
Operation Power up When the BEE III is turned on, it will go through a complete self test. The radar will first perform a light test, in which all of the display's indicators will light, and then the radar will perform a speed test on the internal circuitry When the BEE III is first plugged in, it will also go through a complete self test and then power down. Thi s allows the user to know the radar is OK when the remote batteries are dead.
To perform the tuning fork te st, strike the patrol 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. While co ntinuing 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.
Power Source Cigarette lighter receptacles have been the traditional source of power for traffic radar. However, poor grounding, electronic ignition bleed over, and alternator noise in newer cars can combine to create an unacceptably high level of ambient electronic i nterference. In some instances, an unusually noisy vehicle ignition/alternator noise can result in false readings and/or reduce the range of the BEE III.
IV. MPH BEE III Specifications The MPH BEE III is designed for convenient use by law enforcement agencies to measure the speed of motor vehicles when operate d from a moving or stationary patrol vehicle.
