BEE 36 (Series A)
M.P.H. Industries, Inc.

CPL Approved.

OPERATION

• multi-piece system
  -- remote control
  -- computer module
  -- readout display module
  -- forward looking antenna (weather proofed)
  -- 2nd optional rear facing antenna (weather proofed)
• X, K and Ka models available
• Instant On or continuous
• stationary or moving mode
  stationary -- measures on-coming AND going traffic
  moving mode (front antenna) -- on-coming traffic only
  moving mode (rear antenna) -- going traffic only
  (only one antenna active at a time for either stationary or moving mode)
• Audio Doppler (Target)
• Manual-lock (Speed), separarate display
• Pacing mode -- radar in stationary mode measures patrol car speed
• supplied with 2 calibrated tuning forks

CONTROLS

• Instant On (FRONT / STANDBY / REAR)
  FRONT -- transmit, front antenna
  STANDBY -- radar in standby, on but not transmitting
  REAR -- transmit, rear antenna
• Manual Lock (LOCK / RELEASE)
• Moving/Stationary switch (MOV / STA)
• Town / Highway (HIWAY / TOWN)
  In moving mode should use
  -- TOWN for patrol speeds to 35 mph,
  -- HIWAY for speeds above 35 mph.
• Audio Volume
• Display Lighting
  BRIGHT -- brighten displays
  DIM -- dim displays
• Test
  SEG CK -- check display segments
  ICT -- Internal calibration test
  -- In stationary mode displays 32 in target window if passes.
  -- In moving mode displays 32 in target and patrol car windows if passes.
  -- Florida units display 32 in patrol window and 31 in target window.
• On/Off

DISPLAYS / INDICATORS

• Display (LEDs) -- Target Speed
  stationary: 20 to 129 mph
  moving mode: 20 to 209 mph (max closing speed)
  

• Display (LEDs) -- Locked (target) Speed

• Display (LEDs) -- Patrol Car Speed
  20 to 79 mph

  (wider speed measuring ranges may be special ordered)

• Speaker -- tone proportional to target Doppler frequency

• Indicators
  LV -- low voltage indication
  RFI -- Radio Frequency Interference
  CD (optional) -- Coherence Detector: indicates harmonic frequencies present
  RUN (not all units) -- Indicates RUN or STANDBY mode

• Runs calibration test automatically (periodically). Target display shows 31 and patrol car speed display shows 32 when test running. (Florida users only)
