Use the ECOXGEAR speaker in accordance with any music or noise rules and regulations. 2.) Properly seal the ECOXGEAR prior and after each use when in humid or water environments to avoid water damage to the internal components. Salt water / air is particularly corrosive. Always make sure that the gaskets are sealed when in a salt water environment and that the unit is properly rinsed off after use. 3.) Properly clean the ECOXGEAR and ensure the gaskets have no sand, dirt, or water on them prior to storage. 4.) Store your unit with all caps properly sealed to avoid long term internal moisture damage inside your unit. 5.) Completely dry and clean your ECOXGEAR prior to attempting to charge the unit. 6.) Return the ECOXGEAR to Grace Digital if you suspect water ingress into the unit or if the unit has experienced a severe impact that may have affected the integrity of the unit to take on water. You should never 1.) Never charge your ECOXGEAR if you suspect water has entered the device. Charging a device with water inside could be potentially hazardous and cause fire or a spark. 2.) Never use your ECOXGEAR if you have dropped it or thrown it against a hard surface which may have destroyed the integrity of the speaker, housing, or gaskets. In the event of a severe impact to your unit, please return the unit to Grace Digital to review for potential damage. 3.) Never open the auxiliary doors in a water environment. This could cause water to ingress into the unit which could potentially be hazardous and cause a fire or a spark. 4.) Never connect a device to the auxiliary input jacks when in a water environment. The auxiliary jacks should only be used in a dry environment. 5.) Never attempt to fix, repair your ECOXGEAR unit. Please send it back to Grace Digital for any assessments and repairs. CARE, MAINTENANCE & PRECAUTIONS: 1.) The unit is waterproof only when the caps and door are properly closed. 2.) Close the caps and door properly before use. If the unit is placed in water without the caps or door properly closed, water may enter into the unit and void your warranty. 3.) Dry unit completely before opening the caps or door. Do NOT open the caps or door if wet or in a wet environment. 4.) Do NOT apply excessive force to any surfaces of the unit when wet or in a wet environment. 5.) Do NOT use or store the unit in places with high temperature. 6.) AVOID prolonged exposure to ultraviolet radiation (UV sunlight) and strong magnetic fields. 7.) Periodically check the rubber seal on the caps and door for premature wear. 8.) Periodically clean the rubber with a soft moist cloth and ensure no objects such as dirt, hair, sand are on the rubber seal ring. Do NOT use any oily solvent or chemicals for cleaning. 9.) Rinse off the unit with tap water after use in salt water or swimming pool. 10.) Power and / or charge the built-in rechargeable battery for portable use by connecting the AC cord to an AC outlet. 11.) Noise and audio distortion may occur when the batteries are nearing end of charge. 12.) Do NOT remove the built-in…
