Never charge a battery which is swollen, leaking or damaged.
Never use a modified or damaged charger. Only charge the battery on non-flammable surfaces (do not
charge the battery on flammable surfaces such as carpet or wooden floors) and do not charge near
flammable materials. Charge the battery on a non-conductive surface in order to prevent any damage,
in particular relating to a short-circuit.
Keep the battery and charger out of reach of children.
Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type.
Batteries (battery pack or batteries installed) shall not be exposed to excessive heat such as sunshine,
fire or the like.
OPTIMAL CONDITIONS FOR USING THE BATTERY
Before using a Focal device with a built-in lithium-ion battery for the first time, it is advised to charge the
battery completely in order to maximise its autonomy and service life (wait approximately three hours for
the battery to fully charge). Do not over-charge the battery or let it discharge excessively.
In order to preserve the integrity of your headphone battery, and when left unused for extended periods,
recharge the battery regularly, at least once about every three months.
Turn off battery-powered devices when no longer in use.
For optimal use, do not use the headphones with a built-in battery in places with very high or very low
temperatures (below -5°C and above 40°C).
Please contact your Focal retailer if you encounter any problems.
