The Revive battery pack is used to power the molding tip customization process. Once you complete the molding process, you can also use it for spare battery power to extend your listening time.
To clip the Revive on to your earphones, simply align it with the 3-ring charge port on your earphone Bluetooth cable and press it into place. You will hear it click into place and a light will appear indicating the Revive's battery status. Red means that you have low battery, yellow describes a moderate battery level and green means that it has a strong battery power.
You should have a green light (strong battery) before starting the molding process to ensure that your molding tips get properly customized throughout the whole 60 seconds.
To disconnect the Revive from your earphone cable, simply pull on both pieces. Note: the cables are Kevlar reinforced to withstand this type of pull.
