Charging The Earphones; How To Charge The Battery Using The Usb Cable - RBH Sound EP-SB User Manual

EAR TIP COMPARISON (CONTINUED)
IMPORTANT: It is important that you use the right size tip for your ears
for optimal sound quality. Using a tip that is too small will not provide a
good seal for the earphone and may result in reduced sound performance.

CHARGING THE EARPHONES

The earphone comes with a built-in rechargeable battery. Prior to using the
earphone, it is recommended the battery be fully charged for the first use;
this may take up to two hours.
When the power is low, the earphone emits prompt tones every five minutes
and the red LED flashes; at this time the battery should be recharged.

How to charge the battery using the USB cable:

1. Open the cover of charging jack on the right earphone, and plug in
the USB charging cable
2. Plug the other side of USB charging cable into the USB port on a
computer or USB charging station. When the red LED light is ON it is
charging. When the red LED light is OFF it has finished charging.
3. Allow about two hours for a complete charge.
NOTE: The battery is recyclable. Batteries (battery pack or batteries installed)
should not be exposed to excessive heat, such as direct sunlight or fire.
