How do I set up and install batteries in the remote control of the LG LWG07-Series?

Push the rear cover of the remote control outward with your thumb, then insert two new AAA 1.5V batteries with the correct polarity alignment, and replace the cover. Do not use rechargeable batteries, and make sure both batteries are new. Remove the batteries if the air conditioner will not be used for an extended period to avoid leakage. (Page 11)
