The unit is designed with a 12 volt Lead-Acid rechargeable battery. The battery will recharge during
regular operation of unit or when the optional power adapter is plugged in.
The display will indicate dashes in the incline display if the battery fails to provide enough energy. The
unit will still function normally other than the disabling of the incline feature.
If the battery is completely discharged, the workout review will also be truncated if the user is not
striding during the time period. See for contact information to replace the battery
or purchase the optional AC adapter kit.
