Connecting the charger improperly may cause serious damage to the charging
case. Any damage caused by misuse is not covered by the warranty.
•
Use only USB Type-C cable. The charging case may be damaged if you use Micro
USB cable.
•
If you charge the Galaxy Buds while the charger port is wet, the Galaxy Buds may
be damaged. Thoroughly dry the charger port before charging the Galaxy Buds.
Getting started
13
•
Chargers and USB cables are sold separately.
•
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.
•
When using a charger, it is recommended to use an approved charger that
guarantees the charging performance.
•
Keep the charging case closed while you store or charge the earbuds, or when
you charge the charging case.
•
If you touch the charging contacts while charging the charging case, it may
affect charging.
•
If there is sweat or liquid on the charging contacts, corrosion may occur on the
Galaxy Buds. When there is sweat or liquid on the charging contacts or earbuds,
clean them before inserting the earbuds in the charging case.
•
Even if you do not remove your earbuds from the charging case after the earbuds
are fully charged, it will likely not have a huge impact on the life of your Galaxy
Buds.
•
If you will not be using your Galaxy Buds for a long time, store them after they
are charged.
•
Using a power source other than the charger, such as a computer, may result in a
slower charging speed because of a lower electric current.
•
While charging, the Galaxy Buds and the charger may heat up. This is normal and
should not affect the Galaxy Buds lifespan or performance. If the battery gets
hotter than usual, the charger may stop charging.
•
If the Galaxy Buds are not charging properly, take the Galaxy Buds and the
charger to a Samsung Service Centre or an authorised service centre.
•
Avoid bending the USB cable. Doing so may damage or reduce the lifespan of the
USB cable. Never use a damaged USB cable.
