Only) This device complies with Part 15 of the FCC rules. Operation is subjected to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received), including interference that may cause undesired operation. NOTICE This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not used in accordance with the instructions, may cause harmful interference to radio communications FCC WARNING Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. Proper connections must be used for connection to a host computer and/or peripherals in order to meet FCC emission limits. Safety information NPP-3443 JHDBTC1 ·To ensure the safe use of the product, please read the entire manual before installing and using. ·Keep instructions for future reference. ·Follow all operating instructions and all safety warnings and cautions to ensure safe use. ·Use only accessories / accessories specified by the manufacturer. ·Do not use harsh cleaners, only clean with a dry cloth. ·Do not install on any heat source accessories and keep a safe distance, such as radiators, heat regulators, stoves or other heating equipment (including amplifiers), etc. ·If you need maintenance, please consult the relevant qualified maintenance personnel. If the following situations occur, the equipment must be overhauled: cable damage, liquid infiltration, foreign matter falling in, rain and moisture, failure to operate normally or equipment falling. ·Do not change, modify or disassemble the equipment without the explicit approval of the party responsible for the equipment. Invalid permissions Waterproof Do not sink into the water as this may cause short circuit, fire or other damage. Use the right power source This product is designed for 12V DC negative grounded battery system. Warning: ·Don’t open, disassemble or modify the machine in any way, otherwise it may cause fire, electric shock or product damage. ·Don’t install in a location that may interfere with the operation of the vehicle. Doing so may interfere with sight or movement, resulting in serious accidents. ·When installing wires, do not crimp or squeeze with screws or sharp metal edges. Route the cables from moving parts or sharp edges. This will prevent crimping and damage to the wires. If the wire must pass through a metal hole, make sure to use a rubber ferrule to prevent the insulation of the wire from being cut off by the metal edge of the hole. It is also recommended to use sealant caulks at any openings that may allow water to enter. ·Before installation, carefully check the surface and rear area of the mounting device to ensure that it does not interfere with existing wires or other objects that may be damaged. NPP-3443 JHDBTC1 ·The installation must disconnect the negative terminal of the vehicle battery to prevent accidental short circuit. ·Don’t place open flames, such as lighted candles, cigarettes, etc. on top of the device. Installation 1. Choose a suitable installation location for the Bluetooth remote control. There should be enough space inside the installation location to connect the player cable to the power supply. Also consider how to use the AUX-OUT interface and route the appropriate extension cable to the accessible area. 2. Fix the Bluetooth remote control with 2 PA 4 * 25mm self-tapping screws from outside to inside. 3. Buckle decorative frame. Choose a suitable installation location so that there is room for connecting the player cable to the power supply later. Consider how to use the AUX-OUT interface and route appropriate extension cables to accessible areas. NPP-3443 JHDBTC1 important! Do not install this device where it can be submerged in water Note: Before the final installation, …

FCC ID: 2AHU2-JHDBTC1 RF EXPOSURE EVALUATION METHOD FCC ID: 2AHU2-JHDBTC1 SAR Test Exclusion Thresholds for 100 MHz – 6 GHz and ≤ 50 mm Approximate SAR Test Exclusion Power Thresholds at Selected Frequencies and Test Separation Distances are illustrated in the following Table. The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(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 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 is applied to determine SAR test exclusion. Maximum measured transmitter power.
