In the boot state, long press for 3 seconds to activate the shutdown options: Power off, Reboot, Screenshot. Short press to turn off/on the screen. Volume +/-: Press +/- to turn up/down the volume. USB-C Port: Used for Charging and File transfer. Reset: Long press it for 3 seconds, the device will be restored to factory settings. SD Slot: Expand storage of the device, maximum support 128GB TF/Micro-SD card. 3.5mm Output: Connect your headphones or external speakers. How to Upload Music or Video Upload from your computer: 1.Use the included USB-C cable to connect the player to your computer.The computer will automatically recognize the device and install the driver. After the installation is successful, Click “My Computer”, you will find an MTP device named “X15” in the list of devices and drives, click on it to access the player’s internal/external SD card and its folders. 2.Copy the downloaded music or videos, e-books and other files from your computer and paste them into the folder here, just like using a normal USB flash drive. How to connect a bluetooth headset: Turn on your Bluetooth headset or Bluetooth speaker: from Settings -> bluetooth, when bluetooth is on, it will automatically search for available devices. You can also manually click Refresh to search again. After finding available devices, click to connect. 4 Basic Operation Adjust screen brightness operating steps: Settings-> Display-> Brightness level Drag the brightness bar to adjust the brightness level. Set screen sleep time operating steps: Settings -> Display-> Sleep You can select 15 seconds, 30 seconds, 1 minute, 2 minutes, 5 minutes, 10 minutes, or 30 minutes. If no operation is performed within the specified time range, the screen automatically closes and goes to sleep. For example, if you often listen to music, you can set the backlight time to 1 minute. After 1 minute, the screen will turn off automatically, but you can still listen to the music, which can save the power of the player. View the remaining disk space operating steps: Settings -> Storage The operating system occupies some storage space, so the total storage space is lower than the actual amount. In addition, video and audio files with the same playback time can take up very different storage space due to different compression ratios (bit rates). Factory data reset operating steps: Settings-> Backup & reset-> Factory data reset. This operation restores factory default Settings. FAQ Player can't charge Normally, when charging, the screen lights up and the battery icon appears on the screen.Troubleshooting methods: First rule out whether there is a problem with the player. a.First use the charger to charge the mobile phone, if the mobile phone can charge normally, but the player can not charge, it is the player charging problem, otherwise, please check your own charger. b.Most of the time, the charging problem is caused by poor contact, you can repeatedly plug and remove, test whether it can charge normally. If the charging is intermittent, it is recommended to change a charging cable for charging. Player does not respond when connected to computer First of all, please rule out whether the USB interface of the computer is good. If 5 you plug in a high-quality U disk and it can work normally, there is something wrong with the player. Otherwise, please change a computer or USB interface. Most of the time, the problem is caused by poor data line contact. The player cannot be turned on In most cases, the player is out of battery, please charge for half an hour, and then long press the power button to try. If the machine still cannot be turned on, please contact our customer service, we will deal with it for you in the first time. FM Radio function not working A.There is no wired earphone, because the player must be wired to use the radio function; B.The earphone is in poor contact with the jack. It is recommended to try another earphone. Warning Do not place the device in an environment where the temperature is too low or too high (below -10C or above 50 "C) for a long time. Extreme temperature conditions can cause equipment deformation and shorten the service life of equipment; Do not use the device during thunderstorms; Please keep the device and all accessories away from children and pets. Accidental swallowing may cause suffocation and other serious consequences; Do not place the device in water for a long time; The battery shall not be exposed to overheating; Don't let the player fall off or rub against hard objects when using; Try to avoid operating the player in a particularly dry environment to avoid static electricity; When using this machine, please store the exported files according to the correct operation method, the company will not be responsible for the loss of files caused by the operation; For personal data stored in the player, you are advised to back up to your computer in time; We do not recommend you to use headphones while driving, as they can make you lose concentration. Excessive volume may cause permanent hearing loss. Therefore, please adjust the volume of your headset to an appropriate level and control the use time to avoid hearing loss. In order to better serve you, the contents of this user manual may be changed;due to the performance and function of the prod…

Evaluation method and Limit According to KDB447498 D01 General RF Exposure Guidance v06 Section 4.3.1 Standalone SAR test exclusion considerations: “Unless specifically required by the published RF exposure KDB procedures, standalone 1-g head or body and 10-g extremity SAR evaluation for general population exposure conditions, by measurement or numerical simulation, is not required when the corresponding SAR Test Exclusion Threshold condition, listed below, is satisfied. These test exclusion conditions are based on source-based time-averaged maximum conducted output power of the RF channel requiring evaluation, adjusted for tune-up tolerance, and the minimum test separation distance required for the exposure conditions.22 The minimum test separation distance is determined by the smallest distance from the antenna and radiating structures or outer surface of the device, according to the host form factor, exposure conditions and platform requirements, to any part of the body or extremity of a user or bystander (see 5) of section 4.1). To qualify for SAR test exclusion, the test separation distances applied must be fully explained and justified by the operating configurations and exposure conditions of the transmitter and applicable host platform requirements, typically in the SAR measurement or SAR analysis report, according to the required published RF exposure KDB procedures. When no other RF exposure testing or reporting is required, a statement of justification and compliance must be included in the equipment approval, in lieu of the SAR report, to qualify for the SAR test exclusion. When required, the device specific conditions described in the other published RF exposure KDB procedures must be satisfied before applying these SAR test exclusion provisions; for example, handheld PTT two-way radios, handsets, laptops & tablets etc.“ [(max. power of channel, including tune-up tolerance, mW)/ (min. test separation distance, mm)] · [√f (GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where: • f (GHz) is the RF channel transmit frequency in GHz • Power and distance are rounded to the nearest mW and mm before calculation • The result is rounded to one decimal place for comparison • 3.0 and 7.5 are referred to as the numeric thresholds in the step 2 below The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm according to f) in section 4.1 is applied to determine SAR test exclusion. When one of the following test exclusion conditions is satisfied for all combinations of simultaneous transmission configurations, further equipment approval is not required to incorporate transmitter modules in host devices that operate in the mixed mobile and portable host platform exposure conditions. The grantee is responsible for documenting this according to Class I permissive change requirements. Antennas that qualify for standalone SAR test exclusion must apply the estimated standalone SAR to determine simultaneous transmission test exclusion. a) The [∑ of (the highest measured or estimated SAR for each standalone antenna configuration, adjusted for maximum tune-up tolerance) / 1.6 W/kg] + [∑ of MPE ratios] is ≤ 1.0. b)The SAR to peak location separation ratios of all simultaneously transmitting antenna pairs operating in portable device exposure conditions are all ≤ 0.04, and the [∑ of MPE ratios] is ≤ 1.0. 3.
