Do I have to use the saline spray?

Electrical signals need a conductive environment to transmit properly. Salt water (also called “saline”) is a good conductor of electricity and is biocompatible. A saline dispenser is included with your NERVANA unit. Simply spray the saline on opposite sides of the left earbud – the one with the blue dot.

While it is not required to use saline with NERVANA, it does help transmit a better quality signal.
