Only use this feature when instructed to do so by the LG Customer Service Call Center. The transmission
sound is similar to a fax machine, and so has not meaning except to the call center.
Press and hold the Inlet Temp button for three seconds, while holding the phone mouthpiece to the
icon or POWER button.
* Product feature may vary according to different models. Refer page 39 for modelwise features for your
purchased model.
