Battery
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

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

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

affect the headset’s lifespan or performance. If the battery gets hotter than usual, the
charger may stop charging.

Connecting the headset
Tips and precautions for using Bluetooth
Bluetooth is a wireless technology standard that uses a 2.4 GHz frequency to connect to
various devices over short distances. It can connect and exchange data with other Bluetooth
enabled devices, such as mobile devices, without connecting via cables.
Notices for using Bluetooth
•
To avoid problems when connecting your headset to another device, place the
devices close to each other.
•
Ensure that your headset and the other Bluetooth device are within the maximum
Bluetooth connection range (10 m). The distance may vary depending on the
environment the devices are used in.
•
Ensure that there are no obstacles between the headset and a connected device,
including human bodies, walls, corners, or fences.
•
Do not touch the Bluetooth antenna of a connected device.
•
Bluetooth uses the same frequency as some industrial, scientific, medical, and low
power products and interference may occur when making connections near these
types of products.
•
Some devices, especially those that are not tested or approved by the Bluetooth SIG,
may be incompatible with the headset.
•
Do not use the Bluetooth feature for illegal purposes (for example, pirating copies of
files or illegally tapping communications for commercial purposes).
