I'm confused about what you have to plug in? The door bell ringer??? How can receivers not require batteries? something has to power them.

The ringers are plugged into an electric outlet and the doorbell button is operated by a small battery. It all works great.

The receivers plug into any household outlets. The ringer has a battery inside of it. Just think of the ringer as a transmitter. When you push the button on the ringer, it transmits a signal to the receivers. The battery in the ringer is very easy to replace.

The door bell button/transmitter uses a battery. The ringer/receiver is plugged into an outlet.

I get that the receivers plug into an outlet but can you use them with batteries as well if you like? I would like to put one of the receivers in my music studio higher up on a wall where there is no outlet so I can see the LED light when I am playing music loud enough that I can't hear the bell.

It can't be easier !! You just plug the door bells into any receptacle in your house, choose your ring tone and after installing the battery on the ring button the system is completed.

Each receiver may need to be coordinated with the hand set. I don't remember how to do it, but there were instructions in the manual. Otherwise, fully charged etc., it may be defective.

The receiver is powered by a plug in brick that converts 110 volts it to 9v 500ma DC. There's no room in the receiver for a battery. You could probably hook it up to a 9v battery; not sure how long that would last.

Only the main receiver requires a phone jack. The other receivers only require a power outlet.

The receiver needs to connect to your sound system and, yes, needs to be physically connected to a power source and your speakers. I use mine at school through our soundboard, so don't know if it hooks directly to the speakers.

You need a TV connected so that your receiver can have a signal. Should be fine when you get your TV connected. I have seen that message before.

Mine does not work either. Turns out the transformer for my bell is 10v 5a, the transmitter instructions says it needs 16v 10a. You can buy a new 16v chime and transformer kit for under 20$... or get a completely wireless setup instead.

The sensors are wireless and battery operated, but the "receiving unit" with audible and visual alarm indicators is wireless but not battery operated, it needs an outlet to be plugged in.

Only batteries are needed. We used it from the front door to an indoor location. Perhaps it was our city environment but the volume was too soft for our use and we put them into electronic waste.

It doesn't need a battery. I think what caused confusion is the need of cordless phones to have a battery to charge to be able to receive a signal. This is an "old fashioned" phone that is directly connected to the phone line. If the electricity goes out, it is not affected.

You either need to use self powered speakers or plug into a receiver with speakers, which will provide the needed power for the speakers.

No... very easy to use and set up. Not sure about your question about the plug head? It is a wireless system. Put batteries in it, select ring tone, and hang on your wall. Then take doorbell and mount it at your door. Done.

A couple things to check. You need an amplifier system of some sort && a 1/4" to 1/8 male male adapter. Fresh batteries are always a must. Turn volume up on both amp and receiver.

Must use special power adapter , take receiver with you to electronic store.

Make sure everything is plugged in and batteries are good then make sure you are in range if nothing check connection on TV or receiver is putting out sound the tower dose take batteries

This particular one needs 4 AA batteries (not included). My older ones use 2 AA batteries. If you set these sensors outside, such as by your front door (one good use is to know when deliveries are made such as from UPS & FedEx and the like since they often don't ring your doorbell) and it gets below freezing, use lithium batteries - expensive but they work all the time and last quite a while.
