STEP 1: After connecting to 12V Direct Current, three indicator lights (red, green and blue) will be on. At that time, a composite heater can be used.
STEP 2: When users are using the heater, only the blue light indicator lighter will be flashing, means the heater is working at 40°C. If you need to turn it off, push ON/OFF button again, (at that time, three indicator lights will be on) and the heater will stop heating.
STEP 3: Three working modes ( 40°C/ 45°C/ 50°C) can be chosen by users, according to their requirements.
STEP 4: After choosing one working mode, (taking 40°C for example) the indicator light will keep flashing when the temperature is below 40°C. Otherwise, the light will keep lighting. At the same time, you can choose another heating mode. If without any action on it, the heater will be on standby after 30minutes.
STEP 5: If you need to use it again, just push ON/OFF button again and start heating.
STEP 6: The heater should be placed on smooth places.
