Frequently Asked Questions
Q: How do I recalibrate the pressure sensor on my C2?
A: To recalibrate, power on the pump, then hold both the Light button (01) and Start/Pause button (03) for 10 seconds. The screen will restart automatically, confirming successful recalibration. This process ensures accurate pressure readings over time.
Q: Why does my C2 automatically shut off during inflation?
A: The C2 has five automatic shutoff conditions for safety: (1) 3 minutes of inactivity, (2) charging cable disconnection, (3) inflation over 5 minutes with less than 2 PSI pressure change, (4) continuous operation above 120 PSI for more than 10 minutes, or (5) completing a full charge cycle. These features protect the battery and motor.
Q: How long does the battery last on a full charge?
A: Under optimal conditions (20-50 PSI pressure range, 25°C ambient temperature), the 4,000mAh battery provides approximately 15 minutes of continuous operation. Actual runtime varies based on pressure requirements and temperature.
Q: Can I switch between PSI and Bar units?
A: Yes. Press and hold the Mode button (02) for more than 1 second to toggle between PSI and Bar pressure units. The selected unit will display on the digital screen.
