TROUBLE SHOOTING:
1. Radar unit will not register a speed: First, reset the system by removing power from the display for 10 seconds,
then re-applying power.
a. On the radar unit, the POWER indicator (green LED) should be lit. If not, verify power is connected to the
display (the radar units get power from the Power/Data cable from the display) If the display is active
(counts down upon power up) then power is connected properly, at least to the display. If not, check the
outlet where the power supply is connected for proper 110VAC (standard household power). If the display
operates (counts down) then check that the cable connections and adapter (if used) are securely
connected. If the Green POWER LED is not lit, then there is most likely a connection problem with the
power data cable. If connecting to a PC, make sure the power supply is connected to the adapter, and is
plugged into to an operating outlet.
b. Verify the READING (Red LED) is on. If not on, make sure the MIN, MAX and FILTER indicator LED’s are
off. If any of these are on, press the MODE/SET button, until all these indicators are off and the MPH and
Km/H indicators toggle each time the MODE/SET is pressed. If the reading indicator does not turn on
after a few seconds, the Radar unit may be defective.
c. Verify the MIN and MAX speed limits are set within the speed you are reading. To check this, press and
hold the MODE/SET button until the MIN speed light comes on, the current minimum speed limit is shown
in the display. Press the MODE/SET button again, and the MAX speed limit is displayed. Press the
MODE/SET button again to exit the set speed limits mode.
d. Verify the operation with a tuning fork. If the POWER indicator, and the READING indicator are both on
(MIN and MAX and FILTER indicators are off) strike the tuning fork to make it ring, and hold it a few
inches in front of the unit. If the Reading indicator goes off, but the display still does not register a speed,
this indicates the radar unit is operating properly, and the problem may be in the cable, cable connection,
adapter, or possibly in the display. Check the connection pins on the cables for corrosion, clean or
replace as necessary. If no input configuration operates with multiple radar units, then the Display input(s)
may be defective, and will need factory service.
2. Radar works with a tuning fork, but will not read a pitch speed. If all items in 1 above are OK check the following:
a. Verify the FILTER setting is not too high. With the POWER and READING indicators on (and MIN and
MAX and FILTER indicators are off) Press the DOWN button, the FILTER indicator turns on, and the
display shows the filter number. Adjust this to 8 using the UP and DOWN buttons, then press MODE/SET
button. This low of a filter setting may give false readings, but it provides for maximum range. The
maximum range of the radar unit is typically 8 feet, so make sure the distance from the radar unit to the
net line is less than 6 feet.
b. If step a above allows the radar unit to read the ball speed, it is recommended that the filter number be
increased to the point where it will not read the speed (MAX number, then adjusted back down, ½ way
between 8 and the MAX number.
c. If step a above makes the radar unit continuously false read, press the UP button, then the MODE/SET
button, repeating this until the false readings stop. Verify the radar unit reads the intended target (pitch a
ball). If the speed cannot be registered, then there is a noise source too close to the radar unit. The noise
source must be shielded or moved, or the radar unit must be positioned CLOSER to the net.
