Rechargeable battery
Open the compartment and insert the rechargeable battery, first push on the contacts, and then push and insert the rear. Connect a part of the charging cable into the connector (7), 5V DC input and the other part to a 5V USB power supply (not supplied). The charge from any mobile will work.
The radio will charge in 3 hours, do not have it charging more than 24 hours in a row to prevent the battery from deteriorating. The battery life is 14 hours approximately at medium volume. Higher volumes reduce battery life.
*Note: If you use headphones, (not included), the battery life is the best possible and increases up to approximately 19 hours.
Use with batteries
