What are the "2 non-standard batteries required"? Will phone work in a power failure?

That description about "2 non-standard batteries" appears to be in error. The manual for this phone is available at http://cdn-media-att.vtp-media.com/ecp/documents//product_Product/1889//8359/CL4940_UM_6.pdf. If you look through the manual carefully, you will see that it specifies a power adapter, but makes no mention of batteries. On page 13 of the manual, it says: This telephone provides minimal functionality during a power failure. When AC power is not available, the screen is blank and many telephone features do not function. Only touch-tone dialing and handset volume adjustment are supported. The telephone uses power from the telephone line to enable you to make and answer calls using only the handset and dialing keys.

Phone is provided with an AC cord. There does not seem to be any provision for batteries, so only basic dialing would work--other features, not.

I would suggest go for the Cortelco brand - that works without power.You can view the reviews. I love the phone, simple and straightforward,no issues to date.

This unit cannot be directly use with normal device since it need to be powered. A battery adapter need to be added on line with the cord and the pin assignment need to match with the phones too.

require 2 batteries but you should have 4. 2 spare and charged in case of emergency.

Yes, it will work when there is no power. This is the sole reason why I purchased this phone as my previous one was on its way out.

These phones were replacements for my telephone system so I don't know if they work without the system. Even my jacks in the location ONLY work with systems phones. I do not use batteries with these phones. They must be wired thru the electrical system because when there is a power failure the phones don't work. (maybe just line 1, I believe)

It requires batteries only if you want to use ALL features of the phone. Without batteries the phone works fine (you can make and receive calls), the speakerphone works great and the display works for making and receiving calls (you see the number you are dialing, but it is not backlit). Without batteries you can't use Caller ID, and the display is never backlit. It also briefly displays a "check batteries" message each time you use the phone. I don't care about the battery-dependent functions because I just wanted a phone that would make and receive calls during a power outage, and the screen works sufficiently to do that during an outage. I hate using batteries if I don't have to so I haven't ever put them in. I'm sure it can do other things too that would work if I used the batteries, but I've never tried. If you are looking for a basic phone you can keep plugged into a phone jack without the need for AC power OR batteries -- this is it. It will ring for incoming calls, show the number you are dialing for outgoing calls and the sound is great. As a bonus the speakerphone works without batteries, Call Waiting still works fine (if you have it) and so do the MUTE and FLASH buttons on the phone. I haven't tried Audio Assist so I don't know if it's battery dependent. It's a real cost-saver that you DON'T have to put in any batteries to get all the basic phone functions. This makes it a truly great backup phone -- but because the sound and speakerphone are so great I use mine daily in my home office. (However I still use it without batteries because I already have an answering machine and call log on the main house phone). One more thing...if you're just keeping it in a closet until the power fails...you won't have to find batteries for the phone. Save those for your flashlight ;) Show

I have no idea. These are simply two AAA sized batteries. What "type" of battery I do not know which is an important point. What the key must be is the connector on the end of the wires that plugs into the phone. Good luck. It would be nice if "they" standardized a simple point such as this.

check the battery in YOUR phone / user manual / web site for correct battery model number

there is no battery in the main unit and on page 12 of the operating instructions it states ' the unit will not work during a power failure'. Other than that it's a great phone sustem.

My iPhone had no problem. I think most if not all smart phones are made to take either 110 or 220 so they can be sold worldwide without having to change voltage requirement. Same thing for my MacBook Air. Be careful with other appliances such as hair dryers and electric tooth brushes and the like.

This is not mentioned in manual.By experiment, the phone book survives power failure. I have no idea whether it is stored in the base station or one or morte handsets. The manual says base station ahndset works during power failure.Larry

Battery pack came with it -- it a 2.4V 400mAh Ni-MH. Haven't had to replace battery yet. Will probably need a new phone before battery. Like the phone. Haven't had any troubles with it.

Yes, any regular phone with RJ11 modular plug. If it works with traditional phone lines, it should work with Phone Power adapter.

No. The base requires electricity. If power is out, these phones will not work.
