2ARRB-MB600TRUE WIRELESS EARBUDS

MOTO BUDS 600 ANC TRUE WIRELESS EARBUDS For: MOTO BUDS 600 ANC User Guide Safety instructions DANGER To avoid hearing damage, limit the time you use earbuds at high volume and set the volume to a safe level. The louder the volume, the shorter the safe listening time is. WARNING These true wireless earbuds are compliant with all relevant standards regarding electromagnetic fields and are, when handled as described in the User Guide, safe to use. Therefore, always read the instructions in this User Guide carefully before using the device. • Listen at reasonable volumes for reasonable periods of time. • Be careful not to adjust the volume continuously upwards as your hearing adapts. • Do not turn up the volume so high that you can't hear what is around you. • You should use caution or temporarily discontinue use in potentially hazardous situations. • Excessive sound pressure from earbuds can cause hearing loss. • Using earbuds with both ears covered while driving is not recommended and may be illegal in some areas while driving. • For your safety, avoid distractions from music or phone calls while in traffic or other potentially dangerous environments. • Replacement with incorrect type batteries may cause an explosion. Make sure to use original batteries. • Do not replace a battery with an incorrect type that can defeat a safeguard (for example, in the case of some lithium battery types). • Disposal of a battery into fire or a hot oven, or mechanically crushing or cutting of a battery can result in an explosion. • Leaving a battery in an extremely high temperature surrounding environment can result in an explosion or the leakage of flammable liquid or gas. • The battery subjected to extremely low air pressure may result in an explosion or the leakage of flammable liquid or gas. Do not shock the battery at a high altitude. CAUTION •Do not expose earbuds to excessive heat. •Do not drop your earbuds. •Earbuds shall not be exposed to dripping, splashing water. •Do not allow your earbuds to be submerged in water. •Do not use any cleaning agents containing, alcohol, ammonia, benzene, or abrasives. •If cleaning is required use a soft cloth, if necessary dampened with a minimum amount of water or diluted with a minimum amount of water or diluted mild soap, to clean the earbuds. •The integrated battery shall not be exposed to excessive heat such as sunshine, fire or the like. •Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type. •Disposal of a battery into fire or a hot oven, or mechanically crushing or cutting of a battery, can result in an explosion. •Leaving a battery in an extremely high temperature surrounding environment can result in an explosion or the leakage of ammable liquid or gas. •A battery subjected to extremely low air pressure that may result in an explosion or the leakage of ammable liquid or gas. •Replacement of a battery with an incorrect type that can defeat a safeguard (for example, in the case of some lithium battery types). Operating temperature and humidity •Store in a place where temperature is between -20°C (-4°F) to 50°C (122°F) (up to 90% relative humidity with no condensation). •Operate in a place where temperature is between 0°C (32°F) to 45°C (113°F) (up to 90% relative humidity with no condensation). •Battery life may be shorter in high or low temperature conditions. Welcome... to your new MOTO BUDS 600 true wireless earbuds! •Wireless charging case. •Charge the charging case battery with either a USB-C cable or wireless charger. •Up to 21 hours total playtime with the charging case. •Active noise cancellaton setting. •Touch control for powering on/off and music play/pause. •Use either earbud individually for call and music playback. •Lower power consumption to increase battery life. •Water resistant buds (IPX5). •Smart voice assistant (Siri® and Google Assistant TM ). •Connect 2 mobile devices through Bluetooth at the same time. •Bluetooth 5.2 •Simpler Bluetooth pairing with the Motorola smart phone or an Andriod phone.

Meizhou Guo Wei Electronics Co., Ltd ADD: AD1 Section, Economic Development Area, Dongsheng Industrial District, Meizhou, Guangdong, China. Tel: 0755-2573 6666 Email: [email protected] Date: 2022-11-02 FCC certification No. Cover Letter We, Meizhou Guo Wei Electronics Co., Ltd, hereby submit justification for placing the FCC certification No. in the associated charging case. According to the FCC regulation, the FCC certification No. should be printed on the earbuds, but as the earbuds are too small to print the label (FCC ID: 2ARRB-MB600) , it will be moved to the charging case. The details are as below: A. Side surface (A): The side surface does not provide enough physical space to fit the printing of the FCC certification No. according to below reference picture. B. Top cover (B): The top cover does not provide enough physical space to fit the printing of the FCC certification No. according to below reference picture. Conclusion: Based on the above description of area A to B, we conclude that the device is unquestionably too small for enabling the FCC certification No. to be printed onto any surface. We therefore request to move the FCC certification No. to the charging case. Label: Best regards, Signature: Raymond Leung Engineering Manager

Shenzhen Accurate Technology Co., Ltd. Report No.: SZNS221020-48207E-RFA Version 15: 2021-11-09 Page 11 of 63 FCC-BT；RSS-BT FCC§15.247 (i), §1.1307 (b) (3) &§2.1093 – RF EXPOSURE Applicable Standard According to FCC §2.1093 and §1.1307(b) (3), systems operating under the provisions of this section shall be operated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of the Commission’s guideline. According to KDB 447498 D04 Interim General RF Exposure Guidance SAR-Based Exemption: SAR-based thresholds are derived based on frequency, power, and separation distance of the RF source. The formula defines the thresholds in general for either available maximum timeaveraged power or maximum time-averaged ERP, whichever is greater. Per § 1.1307(b)(3)(i)(B), for single RF sources (i.e., any single fixed RF source, mobile device, or portable device, as defined in paragraph (b)(2) of this section): A single RF source is exempt if: 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. This method shall only be used at separation distances (cm) from 0.5 centimeters to 40 centimeters and at frequencies from 0.3 GHz to 6 GHz (inclusive). P th is given by: Shenzhen Accurate Technology Co., Ltd. Report No.: SZNS221020-48207E-RFA Version 15: 2021-11-09 Page 12 of 63 FCC-BT；RSS-BT For worst case: Exemption limit: For f=2.48GHz, d=0.5cm, the P th =2.72mW The higher of the available maximum time-averaged power or effective radiated power (ERP): The antenna gain is -1.98dBi(-4.13dBd), 0dBd=2.15dBi The maximum tune-up conducted power is 2.5dBm (1.78mW), which less than 2.72mW@2480MHz exemption limit. So the stand-alone SAR evaluation can be exempted.
