CONTENTS What’s in The Box SkyTrak + Unit USB Cable USB Adaptor 2 UNIT OVERVIEW Your SkyTrak + unit has three LEDs, a USB port and a power button. All configuration and usage of the device is via the SkyTrak + application on your computer, tablet or smart phone. COMPATIBLE PLATFORMS SkyTrak + is compatible across many platforms such as smartphone, iPad, Android Tablet, or PC. You can refer to www.skytrakg olf.com for the latest list of compatible devices. SET UP TIP For optimum performance, we recommend that you use a mat for both indoor and outdoor use. 3 POWERING ON AND CHARGING Powering On/Off To turn on SkyTrak +, press the power butt on. The power LED w ill turn GREEN , the WiFi LED will turn RE D and the Read y LED will tur n RED, you can start connecting SkyTrak + to your mobile devi ce. To tur n off SkyTrak +, press th e po wer button again. Chargi ng Charge the SkyTrak + unit for 6 hours prior to i nitial use. Plug the US B ca ble into a PC or other USB char ger,such as your mobile phon e cha rger,to charge the internal battery. The power LED will turn AMBER wh en SkyTrak + is charg ing. SkyTrak + contains a Li-Polym er rechargea ble battery that can op erate up to 4 hours o n a full cha rge. 4 CONNECTING THE WIRELESS Activate Wi-Fi on your mobile device or PC. Make sure that the SkyTrak + unit is powered on. Connect your mobile device or PC to the access point that starts with "STPLUS”. Start the SkyTrak + application on your mobile device or PC. You can go to www.Skytrakgolf.com to download the application. Once the SkyTrak + unit detects the connection from the application, the ‘Wi-Fi’ LED will turn green while the 'Ready’ LED will turn red and a laser dot will be shown on mat. Place your golf ball on this laser dot. Once the golf ball is found, ‘Ready’ LED will turn green. 5 HITTING YOUR FIRST SHOT Once the SkyTrak + unit is connected and dis playing the red laser on the mat, plac e the golf ball or tee on the dot. Make su re the SkyTrak + unit is placed on the same levell as the hitting surface. Whe n a ball is it, the red laser will tur n off and you can view your data in the application. The red laser will turn on again when the unit ready for you to hit yo ur next s hot . 6 7 CARE INSTRUCTIONS SkyTrak + uses advanced optics that are behind the plastic window. Scratches and dust or other issues that impact the window quality may interfere with SkyTrak Plus operation. Keeping the window clean and scratch-free will ensure the measurement accuracy and longevity of your SkyTrak + system. You may purchase a carrying case to keep your SkyTrak + unit protected from www.skytrakgolf.com. To clean the plastic window, use a small amount of water and wipe with a clean cotton cloth in a single wipe. Do not use any chemicals to clean the window. TROUBLESHOOTING Problem Solution When charging, Power LED does not come on. Check if USB cable is connected to valid power socket. Power LED blinking red and unit turns off after 50 seconds. Battery is low. Connect the USB cable and charge the unit. The Power LED will turn GREEN when the unit is charged and device is in operational mode. It will turn AMBER if the device is in charging mode. Wi-Fi LED is not turning green, Make sure to start the application AFTER connecting to the unit's Wi-Fi to your device. The SkyTrak + unit LEDs show connected only when the application is open. Wi-Fi and Power LEDs are green, but Ready LED is red. Ball is not found. Ensure the SkyTrak + unit is placed correctly and not tilting. For the SkyTrak + unit to operate correctly, it must be placed perpendicular to the ground. Results seem inaccurate. Be sure to position the ball correctly on the red dot and make sure the unit sits level with the hitting surface. If using a tee, make sure the base of the tee is on the red dot. 8 DOWNLOADING THE APPLICATION Go to www.skytrakgolf.com from your smartphone, tablet, or computer’s browser to download and install the windows Application. 9 10 WARNINGS AND SAFETY INFORMATION FCC Regulatory Information This device complies with part 15 of the FCC rules.

Set the center frequency of the instrument to the center frequency of the transmission. Set RBW ≥ OBW if possible; otherwise, set RBW to the largest available value. Set VBW ≥ RBW. Set detector = peak or average. The zero-span measurement method shall not be used unless both RBW and VBW are > 50/T and the number of sweep points across duration T exceeds 100. (For example, if VBW and/or RBW are limited to 3 MHz, then the zero-span method of measuring duty cycle shall not be used if T ≤ 16.7 microseconds.) The transmitter output is connected to the Spectrum Analyzer. We tested according to the zero-span measurement method, 6.0(b) in KDB 558074 D01 DTS Meas Guidance v05r02. The largest availble value of RBW is 8 MHz and VBW is 50 MHz. The zero-span method of measuring duty cycle shall not be used if T ≤ 6.25 microseconds. (50/6.25 = 8) The zero-span method was used because all measured T data are > 6.25 microseconds and both RBW and VBW are > 50/T. The RF output of EUT was connected to the spectrum analyzer by RF cable and attenuator. The path loss was compensated to the results for each measurement. Set to the maximum power setting and enable the EUT transmit continuously. The EUT was operating in controlled its channel. Use the following spectrum analyzer settings: Span = Zero Span RBW = 10MHz (the largest available value) VBW = 10MHz ( RBW) Number of points in Sweep >100 Detector function = peak Trace = Clear write Measure Total and Ton Calculate Duty Cycle = Ton / Total 5.7.3 Test Setup EUT Spectrum Analyzer - Page 51 of 117 - Report No.: HB20250730051E-01 Add:Room 102, 201, Building 2, Yuanwanggu RFID Industrial Park, Tongguan Road, Tianliao Community, Yutang Street, Guangming District, Shenzhen,China Tel: (86-755) 29989321 Fax: (86-755) 29985110 Web:www.sz-hongbiao.com 5.7.4 Test Results EUT: ST MAX Model Name: SKYTRAK MAX Pressure: 1012 hPa Test Voltage: DC 3.7V from battery Test Mode: TX b/g/n(20/40) Mode / CH06 ANT 1: Mode Data rate Frequency (MHz) T on (ms) T total (ms) Duty Cycle (%) Correction Factor (dB) 1/T (kHz) b 11 Mbps 2412 12.422 12.816 96.93 0.14 0.08 b 11 Mbps 2437 12.422 12.834 96.79 0.14 0.08 b 11 Mbps 2462 12.422 12.852 96.65 0.15 0.08 g 54 Mbps 2412 2.066 2.188 94.42 0.25 0.48 g 54 Mbps 2437 2.064 2.214 93.22 0.3 0.48 g 54 Mbps 2462 2.064 2.276 90.69 0.42 0.48 Note: 1.
