Charging the battery

• Fully charge the battery when using for the first time.

and an indicator lamp will flash in red. When these beeps sound, charge the battery.

• It takes about 3 hours to charge the battery fully. (This time may vary depending on usage conditions.)

• While the battery is charging, the product's Bluetooth connection remains disabled and therefore the product

cannot be used.

• When inserting the USB charging cable into the USB port or battery jack,

check that the jack is facing in the correct direction before inserting it directly (horizontally).
