REVEX Home Call 2 XP1710B-25 Purchased for my mother and opened, but she entered a facility before using it, so it's almost unused. I checked the operation again for the listing. There are no functional problems, and there are no scratches or stains. 【Product Contents】 Receiver chime, 2 transmitters, instruction manual 【Power Supply】 Receiver chime / 3 AA alkaline batteries (sold separately) Transmitter / 2 button batteries (CR2032) The receiver chime and one transmitter have been opened, so there is no packaging. It will be wrapped in cushioning material for shipping. The other transmitter is unopened. You can choose your favorite sound from a variety of options, from cute melodies to alarm and siren sounds. (Photo 8) You can see the location called at a glance with the 6 color-coded areas. The transmitter can be used in places where it may get wet. Announcements with a wide variety of ringtones and voices (64 sounds) Transmitters and receivers can be added 【Size】 Receiver chime: Width 7.2 x Depth 3.1 x Height 9.6 cm Transmitter: Width 6 x Depth 2.2 x Height 7 cm I think this is a very useful item for home care.
