E-P3+ MOTOR USER’S MANUAL
FIRMWARE UPDATE
The firmware is the heart of the motor, the intelligence that manages the sensor signals (frequency sensor, torque, and speed sensor) and converts them into a fluid and pleasant motor control for the cyclist. During the research of better solutions, Polini Motori updates the firmware constantly, giving the users the possibility to enjoy the use of the improvements on the control even after the purchase.
The firmware is identified by a progressive serial number. The higher number corresponds to the latest and most advanced version than the previous one.
