CPL Approved.

OPERATION

• multi-piece K band radar
  -- forward and rear facing antennas
  -- processor / display unit with wired remote
• stationary or moving mode
• measures on-coming or same-lane traffic
  -- can track targets traveling in same lane/direction
• Instant On or continuous
• Audio Doppler (Target)
• Manual-lock (Speed)
• stopwatch mode
  Operator inputs distance between objects (known in advance), and pushes a button when a target passes each object (radar calculates time between button pushes); radar computes target speed from distance (known) divided by time (button pushes); and displays target speed and time (to travel between objects). Radar does not transmit in this mode.
  -- target window displays calculated speed
  -- patrol car window displays time from operator inputs (LOCK/RELEASE switch)
  -- distance set with THUMBWHEEL switches

• Range Control
• Manual-lock (Speed)
• Mode switch
• Volume (audio target Doppler tone)
• Audio Squelch -- squelch target Doppler audio tone
• Test -- test lights, timing circuits, and transmit frequency
• others?

• Display -- Target Speed
  stationary: 15 to 199 mph
  moving mode: max closing speed 199 mph
  same lane/direction target
  -- speed difference (between radar and target) must be between 3 and 25 mph.

• Display -- Patrol Car Speed
  15 to 80 mph (99 mph max)

• speaker -- tone equal to target Doppler frequency

• Display Messages
  rF -- RFI (Radio Frequency Interference) present
  Lo V -- low voltage (operation inhibited)
  Er-- frequency drift (out of spec) or failure (operation inhibited)
  JA -- STANDBY mode only, radar detects jamming signal from another transmitter

• Auto Calibration - automatically checks crystal oscillators every 50 ms (0.05 sec).
• automatically clears displays when operator changes mode.

• speed displays automatically adjust brightness to lighting conditions
