What type of batteries does the YAP1F remote controller require and how do I replace them?

The YAP1F remote controller requires two 7# (AAA 1.5V) dry batteries. To replace them, lift the cover along the direction of the arrow, take out the old batteries, insert the new ones ensuring correct + and - polarity, then reinstall the cover. When replacing batteries, do not use old or different types of batteries as this may cause malfunction. (Page 7)
