Problem Description	Possible Resolution
The unit won't “arm”.	Ensure you have positioned the cursor over the ‘Arm” button on the PureLaunch™ software installed on your computer. Check all connections from the computer to the unit. Contact our Department for further assistance.
The unit won't power on.	If using as battery operated: Ensure the battery is fully charged. The “green” battery light should be displayed when you press the battery indicator button. If the light is “yellow” or “red” then recharge the battery with the supplied power charger. Ensure the unit is turned “on” using the power button under the middle section of the unit. If using electricity: Ensure the unit is receiving power from the electrical outlet. Ensure that the unit is turned “on” using the power button under the middle section of the unit. Contact our Department for further assistance.
The readings seem to have deteriorated.	Check the strength of the battery by depressing the small battery indicator button. If the light is “green” then the battery is providing ample power to the device. If the light is ‘yellow' or ‘red' then the displayed measurements and calculations will not function correctly. Turn off the PureLaunch™ unit and close the PureLaunch™ application. Remove the battery and replace with one that is fully charged. Turn on the PureLaunch™ unit and open the PureLaunch™ application. Contact our Department for further assistance.
The Launch Angle measurements appear low.	The bottom front of the PureLaunch™ should be 60” from the golf ball and pointing directly down the target line. Many users have a tendency to keep moving further and further away from the unit which will cause the measured launch angle to decrease.
The Launch Angle measurements appear high.	The bottom front of the PureLaunch™ should be 60” from the golf ball and pointing directly down the target line. If the user is less than 60” then the measured launch angle may increase.
The Clubhead Speed measurements seem low or inconsistent.	The bottom front of the PureLaunch™ should be 60” from the golf ball and pointing directly down the target line. If the unit is not pointed down the target line then clubhead speed will be impacted.
Not all measurements are displayed on the computer.	Sometimes the PureLaunch™ is unable to gather sufficient data to ensure the measurement is correct. This can occur when the readings from one transceiver do not match the readings from the other transceiver. Delete the shot and hit another ball.
Unit displays Clubhead Speed (mostly low readings) and Ball Spin only.	Microphone sensitivity is too high causing the unit to trigger early. This problem rarely occurs and is being addressed by our engineering staff.
Readings appear to be off for shots that go severely to the left.	This happens when the radar “loses” the ball because the ball flight path and club head path are following approximately the same line. Realign either the golfer's target line or the unit so that the ball flight path is more towards the center of the radars view window.
Not getting readings for short iron or wedge shots.	The PureLaunch™ unit uses an internal microphone to ‘trigger' the device. Short irons or wedge shots that are hit ‘thin' or ‘pure' should produce readings but ‘fat' shots generally do not transmit enough noise to activate the trigger. One solution is to use a ‘Lie Board' for these shots. The sound of the club striking the ball and lie board simultaneously will produce enough sound to trigger the unit. Using a tee for short irons and wedges may be tried if a Lie Board is not available.
Why does my Power Transfer Ratio % sometimes look good for topped or thin shots?	Topped or thin (also known as “bladed”) shots can be launched very quickly relative to clubhead speed, but with topspin (which causes the ball to dive into the ground) instead of backspin (which causes the ball to lift). Since PTR% is a function of only two factors, ball velocity and clubhead speed, topped or thin shots may show a high ratio even though other aspects of the ball flight (e.g., spin and launch angle) are undesirable. The user should delete these shots using the Delete Shot button on the Shot tab.
What if some of the measurements displayed are clearly not accurate for the shot I just hit?	Check your setup and ensure monitor, golfer, and ball are in the correct positions. If setup is correct and measurements are still out of bounds, contact us. It is possible that software corruption has occurred and is causing invalid results to be displayed. Check the strength of the battery by depressing the small battery indicator button. If the light is “green” then the battery is providing ample power to the device and therefore this is not the problem. If the light is ‘yellow' or ‘red' then the displayed measurements and calculations will not function correctly.

I want to connect the unit to my computer, but it doesn't have a serial port, it just has USB ports.	Purchase a USB-to-Serial port adapter. We recommend the following 2 manufacturers. Belkin Part # F5U103, www.belkin.com Radio Shack Catalog # 26-183, www.radioshack.com
My external display isn't working	Make sure the PureFlight unit is powered on and positioned properly Make sure the display is connected to the unit with the provided 5-pin cable If you are using one of the older mechanical displays, you must also have a power supply connected to the second 5-pin connector on the display. The newer digital displays do not require a power supply. (Note: Using the digital display without a power supply will drain the PureFlight battery faster. Also, using the digital display with a power supply will not charge the PureFlight battery. ) Run the Display Self Test Press “Mode” and “Club” at the same time. Use "Up Arrow" for Random Number Display, use "Down Arrow" for Consecutive Number Scroll Display Contact our department The self test will not work with the older mechanical displays

For all problems, try this first.	Run the “Full Unit Seft-Test” Use "Down Arrow" and "Mode" at the Same Time to Begin (follow displayed instructions). "TST" Will be Displayed. Select "Up Arrow" for "Yes" or "Down Arrow" for "No". The Unit will then go through a series of tests and display "Passed" or "Failed" at each step. If the unit passes both self-tests, continue on to the more specific problems below. If either test fails, contact our department.
Unit won't power on.	Make sure you firmly press the power button. Make sure the battery is fully charged. To ensure the fullest battery charge for each session, we recommend “draining the battery” then recharging it. Using this method will also ensure the longest battery life for the product. The average life battery is approximately five years depending on charging practices and usage. Batteries can be replaced by the manufacturer. To drain the battery, execute the “Disable the Auto Shutoff” function; Press "Club" + "Up Arrow" at the same time. The unit will display "Disable Auto Off?". Press "Up Arrow" to answer "Yes". Leave the unit powered on and the battery will discharge within 4 hours. To re-charge the battery, turn the unit off. Plug in the power supply to the product and into a surge protected AC outlet or power strip. Power surges can affect the integrity and use of the battery use a surge protected power strip if you have power surges in your area. Charge the battery for 10-12 hours to fully charge. A partially charged battery may not perform as expected and may not hold a charge. A fully charged battery should last approximately eight hours in Mode 1 with a microphone, six hours in Mode 1 without a microphone or six hours with Mode 2. Try powering on with the power supply plugged in. If this works, your battery, the charging circuit, or the unit itself may be damaged. Contact our department.
Unit goes to “Low Batt” a few seconds after powering up.	Make sure the battery is fully charged.

A partially charged battery may not perform as expected and may not hold a charge. A fully charged battery should last approximately eight hours in Mode 1 with a microphone, six hours in Mode 1 without a microphone or six hours with Mode 2. If your Par 4 unit has been sitting unused for several months, you may need to repeat the above procedure 3 times consecutively before using the unit. Try powering on with the power supply plugged in. If it still goes to “Low Batt” right away, your power supply or the 5-pin power connector on the unit may be damaged. (Also see “I think my power supply is bad” below). Contact our department.
Unit goes to “Low Batt” after a few hours, doesn't last for the expected 6-8 hours.	Make sure the battery is fully charged. To ensure the fullest battery charge for each session, we recommend “draining the battery” then recharging it. Using this method will also ensure the longest battery life for the product. The average life battery is approximately five years depending on charging practices and usage. Batteries can be replaced by the manufacturer.

A partially charged battery may not perform as expected and may not hold a charge. A fully charged battery should last approximately eight hours in Mode 1 with a microphone, six hours in Mode 1 without a microphone or six hours with Mode 2. Make sure you have the microphone plugged firmly into the microphone jack. If the microphone is not plugged in or is loose, the radar will be on continuously and will discharge the battery very rapidly (usually 4 hours or less).
I think my power supply is bad.	To test this you need another working Par 4 or working power supply. If you don't have access to another unit/power supply you need to contact our department. Try the suspected “bad” power supply on another Par4 and see if it will charge. If it does, try the other “good” power supply on the Par4 you were having trouble with. If both power supplies work on one unit, but not the other, most likely your battery, the charging circuit, or the Par4 unit itself is probably damaged. Contact our department. If both units work with only the “good” power supply, the “bad” power supply may need to be replaced. Contact our department or purchase a new power supply.
Not getting any readings from shots.	Make sure the unit is powered on and positioned properly for the mode you are using. For Mode 1, position the unit to the side of the tee about 4-18 inches from the ball with the front of the unit pointing down the target line. If you are using the microphone with Mode 1 (to extend battery life) it should be plugged directly into the bottom of the unit and swiveled to point directly at the tee. For Mode 2, plug the microphone into the microphone extension cable and plug the other end of the cable into the bottom of the unit. The unit should be placed approximately 45 inches behind the ball, pointed down the target line, with the microphone cable stretched towards the ball. The microphone should be placed 3-4 inches to the side of the ball, pointed at the ball. (We recommend anchoring the microphone with a few golf tees.) If the golfer is concerned about hitting the unit during the backswing it can be moved a few inches to the side as long as it is still pointing down the target line. Make sure you have selected the proper mode. Press Mode" then "Down Arrow" or “Up Arrow” to select the desired Mode, then "Mode" Again. Make sure the microphone is plugged in fully and positioned properly (for mode 2, mode 1 does not necessarily require a microphone).
Not getting readings from short iron or wedge shots.	Make sure the unit is powered on and positioned properly for the mode you are using.

If the golfer is concerned about hitting the unit during the backswing it can be moved a few inches to the side as long as it is still pointing down the target line. Try putting a club head cover or some other object under the front of the tripod to angle the unit up an additional 10 degrees. High launch angles may not be in the radar “window” long enough to provide accurate data. Try teeing the ball up slightly to ensure solid contact with the clubface to provide a loud enough signal to trigger the unit. The microphone may not always “hear” shots with these types of clubs if you get too far under the ball and catch a lot of turf. Try using the unit in Mode 1 without the microphone attached.
I want to connect the unit to my computer, but it doesn't have a serial port, it just has USB ports.	Purchase a USB-to-Serial port adapter. We recommend the following 2 manufacturers. Belkin Part # F5U103, www.belkin.com . Radio Shack Catalog # 26-183, www.radioshack.com .
My external display isn't working.	Make sure the Par 4 unit is powered on and positioned properly. Make sure the display is connected to the unit with the provided 5-pin cable. If you are using one of the older mechanical displays, you must also have a power supply connected to the second 5-pin connector on the display. The newer digital displays do not require a power supply. (Note: Using the digital display without a power supply will drain the Par 4 battery faster. Also, using the digital display with a power supply will not charge the Par 4 battery.) Run the Display Self Test. Press “Mode” and “Club” at the same time. Use "Up Arrow" for Random Number Display, use "Down Arrow" for Consecutive Number Scroll Display. Contact our department. The self test will not work with the older mechanical displays.
Readings for shots over 200 yards seem to be short.	The distance algorithm has been improved and is now in our PureLaunch and PureFlight products. The new distance algorithm can be installed on any Mode 2 capable Par 4 unit. Please contact for information. As a work around for shots over 200 yards you can make either of the following adjustments; Press Power, then Club and then use the up arrow to adjust the percentage upwards until you are getting better results. Press Units, and use the up or down arrow to adjust Yards (carry distance) to YardsR (Carry + Roll).
Readings appear to be off for shots that go sharply to the left.	This happens when the radar “loses” the ball because the ball flight path and club head path are following approximately the same line. Realign either the golfer's target line or the unit so that the ball flight path is more towards the center of the radar view window.
Unit is on and says “READY” but won't respond to any keypad commands.	You may be able to overcome this problem by unplugging the microphone and leaving the unit on until the battery is fully discharged. If “Auto Shutdown” is disabled, the unit should drain the battery in about 4 hours. If “Auto Shutdown” was enabled, the unit will power off after approximately 5 minutes, you need to keep powering on the unit until it reaches “low batt”. Recharge the battery fully after discharge and see if the unit responds to the keypad now. If it is still not responding, contact our department.
