  Getting started
  1. Radiofrequency exposure
  True Wireless Stereo Earphones HP-TW30 is a radio transmitter and receiver. When in operation it communicates with a Bluetooth ®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 emperatures, never above 40°C (104°F) or below 5°C (41°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.
