Users Manual

MOTO BUDS 135 TRUE WIRELESS EARBUDS For: MOTO BUDS 135 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 This true wireless earbuds are compliant with all relevant standards regarding electromagnetic fields and is, 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 135 true wireless earbuds! • Wireless charging case. • Up to 14 hours total playtime with the charging case. • 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 ). • Bluetooth 5.2 • Simpler Bluetooth pairing with the Motorola smart phone or an Andriod phone. Need help? If you have any problems setting up or using your MOTO BUDS 135, please visit us at motorolasound.com/support Alternatively, you may find the answer in the ‘Help’ section at the back of this guide. This User Guide provides you with all the information you need to get the most from your true wireless earbuds. Before you make call or listen to music you will need to set up your true wireless earbuds. Follow the simple instructions in ‘Getting started’, on the next few pages. Got everything? • Bluetooth true wireless earbuds (with M size earcaps) • Charging case • USB-C charging cable (300 mm in length) • Extra 2 pairs (S and L sizes) of replaceable silicon earcaps • Quick start guide • Warranty 6 1.
