This is the Revex XP700 (receiver chime). It measures 90mm x 90mm x 32mm and weighs 84g. The color is white. It requires 3 AA batteries. It is not for an AC adapter. (Batteries are not included.) I removed it because I installed a chime with a camera. I used a different chime for the call function. The instruction manual is a printout from the web and includes the calling chime, but this product is only the XP700 receiver chime. Thank you for your consideration.
