• The S.C.™ Power contains an on-board generator which powers the Echelon2G console, eliminating the need to
replace batteries as part of its maintenance schedule. As the rider begins to pedal, an LED light illuminates to
provide positive feedback that the generator is powering the console.
• If a battery replacement is required, they are available through Core Connect. Regular use of the S.C.™ Power is
ideal to maintain a charge to the internal battery and maximize its life.
