Charging the battery
Fully charge the battery before using the headset for the first time or when it has been
unused for extended periods. You cannot use the headset while it is charging.
Use only Samsung-approved battery, charger, and cable specifically designed for your
device. Incompatible battery, charger, and cable can cause serious injuries or damage to
your device.
• Connecting the charger improperly may cause serious damage to the headset. Any
damage caused by misuse is not covered by the warranty.
• Do not pull on the charger port cover excessively. This can damage the charger port
cover.
• Use only USB Type-C cable. The headset may be damaged if you use Micro USB cable.
• Chargers are sold separately.
• The headset's battery can be charged in locations with an ambient temperature of
5 °C to 50 °C.
• While charging, the headset will not turn on even when pressing and holding the
Power button.
• To save energy, unplug the charger when not in use. The charger does not have a
power switch, so you must unplug the charger from the electric socket when not in
use to avoid wasting power. The charger should remain close to the electric socket
and easily accessible while charging.
• If there is sweat or liquid on the charger port, corrosion may occur on the headset.
When there is sweat or liquid on the charger port or USB cable, clean them before
connecting them.
• If you will not be using your headset for a long time, store it after it is charged.
