Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must not accept any interference received, including interference that may cause undesired operation. 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 installed in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, the user is encouraged to try to correct the interference by one or more of the following measures: - Reorient or relocate the receiving antenna. - Increase separation between the equipment and the receiver. - Connect the equipment to an outlet on a circuit different from that to which the receiver is connected. - Consult the dealer or an experienced radio/TV technician for help. Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment. SAFETY CONSIDERATIONS • Only use this product in vehicles with 12 volt, negative-ground electrical systems. This product is not certified or approved for use in aircraft. • Mount this product securely to prevent damage or injury in severe conditions. • Do not replace the power wire fuse with one of a different value. Never bypass the fuse. • Listen to your audio system at levels appropriate for operating conditions and hearing safety. INSTALLATION CONSIDERATIONS • Installation requires appropriate tools and safety equipment. Professional installation is recommended. • This product is water-resistant. Do not submerge or subject to high- pressure water spray. • Before installation, turn off the audio system and disconnect the battery system from the audio system. • Install in a dry, well-ventilated location that does not interfere with your factory-installed systems. If a dry environment is not available, a location that is not exposed to heavy splashing may be used. • Before cutting or drilling, check for potential obstacles behind mounting surfaces. • Carefully route all system wiring away moving parts and sharp edges; secure with cable ties or wire clamps and use grommets and loom where appropriate to protect from sharp edges.

Option A: FCC Rule Part 1.1307 (b)(3)(i)(A):The available maximum time-averaged power is no more than 1mW, regardless of separation distance. Option B: FCC Rule Part 1.1307 (b)(3)(i)(B): The available maximum time-averaged power or effective radiated power (ERP), whichever is greater, is less than or equal to the threshold P th (mW) described in the following formula. P th is given by: Option C: FCC Rule Part 1.1307 (b)(3)(i)(C): The minimum separation distance (R in meters) from the body of a nearby person for the frequency (f in MHz) at which the source operates, the ERP (watts) is no more than the calculated value prescribed for that frequency. R must be at least λ/2π, where λ is the free-space operating wavelength in meters.

(B) In the case of fixed RF sources operating in the same time-averaging period, or of multiple mobile or portable RF sources within a device operating in the same time averaging period, if the sum of the fractional contributions to the applicable thresholds is less than or equal to 1 as indicated in the following equation. 1.3 Calculated Result Radio Access Technology Prediction Frequency Output Power Antenna Gain Duty Cycle Tune-Up Time-Averaged Power ERP (MHz) (dBm) (dBi) (%) (dBm) (dBm) Bluetooth 2402 4.22 2.81 100 5.00 5.66 Frequency Option Min.
