You can download the instructions from the beyerdynamic website at www.beyerdynamic.com/p/aventho-y � Do not use the AVENTHO Y if it is defective. Intended use � Only use the AVENTHO Y as described in this product manual. The company beyerdynamic GmbH & Co. KG accepts no liability for damage to the AVENTHO Y or injury to persons caused by careless, improper or incorrect use of the AVENTHO Y, or by use for purposes not specified by the manufacturer. � beyerdynamic is not liable for damage to USB devices that do not comply with the USB specifications. � beyerdynamic is not liable for damage resulting from connection interruptions due to batteries being empty or too old, or due to exceeding the Bluetooth® transmission range. � Please also observe the relevant country- specific regulations before using the AVENTHO Y. Adjusting the volume High volumes and long listening can permanently damage your hearing. � Before putting on the AVENTHO Y, set the volume to minimum. Only increase the volume afterwards. � When listening and speaking normally with the AVENTHO Y, your voice should still be perceptible. � In case of tinnitus, decrease the volume. If necessary, consult a doctor. � Excessively high volumes and long listening times may cause hearing damage. � As a rule of thumb, the higher the volume, the shorter the listening time. Damage from liquids Liquid penetration can damage the AVENTHO Y. � Make sure that no liquids penetrate the AVENTHO Y (e.g. when cleaning). � Do not use solvent-based or aggressive cleaning agents. Risk of swallowing � Keep small parts, such as packaging and accessories, away from children and pets. They constitute a choking hazard if swallowed! Using the batteries Danger from heat, water and mechanical stress Excessive heat, water and mechanical stress may cause explosion, heat, fire, smoke or fumes.
