【Manufacturer's Notes】

*The air-fuel ratio will be displayed when the O2 sensor is activated by exhaust heat. No numerical value will be displayed in cold conditions.
*Even after the engine starts, if the sensor has not reached the activation temperature, no numerical value will be displayed.
*If installed after the manifold junction of a multi-cylinder vehicle, the sensor may not reach the activation temperature.
*Install the sensor boss as close to the cylinder head as possible.
*When connecting to vehicle power (DC12V), remove the button battery.
Connecting to DC12V with the battery inserted may cause malfunction.
