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.
