Special Notes (continued)

Getting started

1. Radiofrequency exposure
Wireless Bone Conduction Headphones are radio transmitters and receivers. When in operation it communicates with a Bluetooth® the equipped mobile device by receiving and transmitting radio frequency (RF) electromagnetic fields (microwaves) in the frequency range 2.4 to 2.48 GHz. This product is designed to operate in compliance with the RF exposure guidelines and limits set by national authorities and international health agencies when using compatible mobile phones.
2. Battery information

• A rechargeable battery has a long service life if treated properly.
• A new battery or one that has not been used for a long period of time could have reduced capacity the first few times it is used. Do not expose the battery to extreme temperatures, never above 50°C (122°F) or below -10°C (14°F).
• For maximum battery capacity, use the battery at room temperature.
• If the battery is used in low temperatures, the battery capacity will be reduced. The battery can only be charged in temperatures between 5°C (41°F) and 40°C (104°F).
• RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE. DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS.
  3. Removal of waste batteries and accumulators
  (Product with embedded battery ONLY)
• In case this product contains a battery incorporated within the product that cannot be readily removed by end-users, SHARP recommends that only qualified professionals remove the battery, either for replacement or for recycling at the end of this product’s working life. To prevent damage to the product, and for their own safety, users should not attempt to remove the battery and should contact authorized independent service providers for advice.
  CAUTION:
  Internal lithium battery in the unit should not be replaced by end-users due to the danger of explosion if the battery is incorrectly replaced and must be replaced with the exact type battery by authorized service providers.
  Avoiding hearing damage
  If the volume on the headphones is too high, permanent hearing loss may occur. Please set the volume to a safe level. You can become habitual to hearing at a high volume that may sound normal but can damage your ears. If you experience ringing in your ears or muffled speech, stop listening and have your ears checked by the specialist doctor. The louder the volume, the more quickly the hearing can be damaged. Hearing experts suggest how to protect your hearing
• Limit the amount of time you use the headphones at a high volume.
• Avoid the habit of increasing the volume so that you do not hear the loud noises around you.
• Turn the volume down if you cannot hear people speaking around you. For setting the maximum volume limit of the connection device, refer to the instruction manual supplied with the connected device. Class B equipment (home-use broadcasting communication equipment): This equipment is intended for home-use (Class B) electromagnetic compatibility equipment and can be used in all areas.

Precautions

The sound level at a given volume setting depends on speaker efficiency, location, and various other factors. It is advisable to avoid exposure to high volume levels, which occurs while turning the unit on with the volume control setting up high, or while continually listening to high volumes. Excessive sound pressure from headphones can cause hearing loss. Adjust the volume to an appropriate level when using the unit.
