How do I turn on the heat?
To turn on the heat, connect your fully charged battery to the cable in the interior pocket of your jacket. Once the battery is plugged in, long press the power button with the ORORO logo placed on the chest of your garment. The LED light on the logo will start blinking red, indicating the preheating process. After 5 minutes of preheating, the heating levels automatically switched to medium level for comfortable warmth. You could press the power button again to cycle through high, medium, and low heating levels.
