5 | BATTERY INFORMATION
The device is equipped with an integrated lithium-polymer battery. The battery cannot be
replaced. Do not attempt to remove the battery from the device since it would damage
the device. The full performance of a new battery is not achieved until after two or three
complete charge/discharge cycles. The battery can be charged and discharged several
hundred times, but it loses its capacity over time.
Disconnect RKING920 from the power supply as soon as the battery is fully charged;
overcharging could reduce the service life of the battery. A charged battery will lose
its capacity if it is not used on a regular basis. Important: Ensure that the battery is fully
charged if you do not use the device for a long period of time. To avoid a complete
discharge of the battery, the RKING920 should be charged at least every 3 months.

RKING920 is operated with a rechargeable battery. Charge the battery completely before
its first use. Read the previous section “Battery Information” before starting the charging

Charging the battery fully may take up to 2 hours.
3. When the battery is fully charged, the Red indicator light will turn Blue. Disconnect
the charger from the headset and the outlet. The headset is ready to use.
