AA batteries are placed in battery pack/inserted into receiver, I only get static/no display (could be the kind of batteries I’m testing it with) Please see pictures for flaws. Please take your time and look over the pictures carefully prior to purchase. We do our best to note and picture as many flaws as we see and or blemishes we find. Feel free to message us with questions or concerns. Use the zoom option/tool on your phone or computer to look over minute details prior to ordering. Thank you!
