Does the unit use voltage from the telephone line or do you have to put batteries in it. My CPR blocker disrupts my modem DSL.

There are no batteries necessary. The unit is powered by a transformer that plugs into a standard wall socket.

The unit does not use batteries. It is powered by a AC/DC transformer. It is not powered by line voltage. We have used this unit with DSL in the house, but always isolated transformers by use of a power strip with filtration.

This Ynit has it's Own Power Source and Requires a Separate Plug-In. Buy this Unit; It really works!

True of any AC appliance, obviously, no power, no go. I live in a rural area where this is a frequent occurrence, so I have to maintain a landline just in case. Even if I used my generator, the wi-fi ISP I use does not, so in a matter of 4 hours, no phone service

i guess if you want to be absolutley safe about it, you could install a circuit breaker. i run my direct off the battery, works fine.

In order to answer this question, I just unplugged my phone. I did not lose any information. I do not have batteries in mine. It must have something to do with the phone line itself

No batteries are needed! Just plug one wire into telephone line (for phone service) and another wire into wall outlet for power (both wires are included with purchase).

This unit must be installed onto a junction box and connected to line voltage power. It does not use batteries.

The wire from the wall outlet goes into the call blocker. Another wire goes into the telephone. The unit comes with easy to understand instructions.

It uses 110V. It is a great piece of equipment. My wife uses it for her neuropathy and it gives her much relief.

No, it will cause the unit to short out, you will need to use a voltage converter

If you have a splitter for DSL use it's important that it is plugged in first (to the wall) and they the line to the phone.Mine came with a manual.

At home I have 2 power lines (120v each), one is for electrical distribution at frontal part of my house , and 2nd line at back side (Bdr, baths etc) and then I use both lines for Air conditioned, heaters, etc. and other items running on 220 V. Previously, I had a failure (at night)in the line going to the front part of the house, so we didn't notice this, and 2 of the AC overheated running in only 110v and one of them even caught fire. so now I plug this unit in electrical outlet (1 switch in 1 outlet per line) . this way, if one of the lines is down, the alarm goes off, it's very loud ! uses batteries as backup. I am very happy with this product.

Anytime you lose power to router your phone won't work. But that is true with almost all land line unless you have battery backup. If you have laptop you can always call 911 from lap top or ipad or cell phone. This basic talk works great. Better than voicp I had thru cable co. and a lot less expensive. Hope this helps

This unit takes batteries and also plugs into the wall. I'd be concerned about buying it though. My CD player died after one use.

Austin,I used this unit integrated into an alarm unit for a friend, but as I remember it is has a dc power jack on it for the 12 volt output. It also includes a dc power cable with female connectors on each end. One end plugs into the power jack, the other end will plug into whatever you to operate. You will need a matching male dc power plug, which can be purchased at Radio Shack etc. Hope this helps,Jack

This filters signal into data & voice. If you use DSL then you hook up the cable from the port labelled DSL to your DSL modem. The telephone port is purely voice.

110 volts regular US house voltage. Not a battery operated unit. This model is an inside camera. Mine are in lookling out windows which works fine and are plugged in to regular wall sockets. They come with LED lights which means good night vision in a dark inside room but they cause a glare on the wiondow when looking out. So I turn the LED lights off on ones looking out thru a window.

I have a digital line and receive DSL with no issue for this phone. Works just like the last one did for over 45 years, clear and no issue with power outages.
