In my recent radio doorbell receiver was plugged directly into an electrical outlet. Here it is different. The 1byone bell is supplied with energy from batteries. A power outlet is not required. Thus, the wireless doorbell is suitable especially for areas where no electricity is available. A classic example would be since the operation in the garden, where you would not hear the bell otherwise. Who wants the bell could also supply a power adapter, this does not belong to delivery. Also the transmitter, which usually depends on the door is powered by a button cell. The button cell CR2032 standard format already included. For the receiver 3 AA batteries are required, which are to get even.
Very modern, the receiver is operated via a touch screen. Thickness buttons do not exist here. For but a nice big lettering. At the transmitter can be mounted under a transparent cover the nameplate. Screws and plugs are included for transmitter and receiver for attachment. Unfortunately adhesive pads do not belong to the set. However, these would have been of particular interest to me.
I have been playing with music in MP3 format to the SD card. The SD card is inserted at the side of the receiver. Play is not a problem. A ring tone is only played 15-20 seconds. For a bell but that is sufficient. The challenge is to cut the songs so justly, so that it sounds good afterwards.
Despite 3 concrete floors, it works fine with the reception. The bell is unmistakable ...
