  WARNING!
Take special care when charging the headphones as they could become hot.
Batteries must only be replaced with rechargeable NiMH 1.2V 900mAh AAA batteries.
There is a risk of explosion if a battery is replaced with an incorrect type.
Batteries contain toxic substances, such as sulphuric acid or lead, which are forbidden from being disposed of with domestic waste. If disposed of incorrectly, these substances can contaminate the ground, subsoil and water. The consumption of contaminated water can lead to serious illness. Legislation requires that specific procedures are used for the disposal of used batteries, and for this reason, it is recommended that car batteries are replaced and disposed of by an authorised Bentley dealer.
