If the set was used for a long time it is possible that there is a feedback due to some capacitor leak within the circuit. use a dryer or wash off PCB and all the board to dry before the battery is plugged back . Check if the fault clears or improves, if so repeat.

I moved some furniture around after christmas and unplugged the phone to do so. Now it does what yours is doing. It needs to be re-set up as if I just bought it. Is it possible yours was unplugged? Suggest you start from scratch with the set-up manual. Personally, I can't find mine. I have the french and am translating it. I can't believe the nonsense I am going through just because I unplugged the stupid phone. Good luck.

I'm pretty sure the speed dial numbers are programmed on a per-phone basis. Most people would not want changes on one phone's speed dial to effect the other phones. I know registering the handsets will not make a difference. If the cordless phone is working, it's registered to the base. This is required so your neighbor cannot buy the same phone model and use your phone line. In the old days cordless phones were permanently linked to one base but now you can get extra handsets on many systems and "register" the phone to work on your base.

There is a "Tone / Pulse" switch or program setting you want set to "Tone". It would be part of the base unit and not an option on the cordless handsets.

Unfortunately there is no simply delete all option So here's what you need to do , ( has uniden phone landline) Menu - down arrow - call blocking - menu key - view number - menu key - delete .. You'll need to do this for each number ... I haven't found a more easier way to do, I assigned a name to all the numbers like bogus 1 or scam 1 https://www.google.com/search?q=uniden+6.0+remove+blocked+contacts ..

The range of a handset can be affected by many things. Try some of the simple, (and free), fixes first. Where is the base unit? Is it near other technology like a TV, wiFi hub or even things like a microwave. Is it near a window or an outside wall? Try moving it to a position nearer the centre of the house so the base unit covers more signal area. How old is the handset and base? Old phones and bases do get weaker as they get older. Are there solid, (brick), walls between you and the base unit when your using the handset? Thicker, denser building material blocks out some or all of the signal from the handset.

I had this exact problem on a D1780 and solved it by un-registering all of the handsets and then re-registering them. Before I did that it would only allow six phones to be registered at a time.

It looks like the Set/Start button might be the right arrow button from the arrow keys to the right of memory buttons. It's possible that it is between the right and down arrows, based on where the manual shows "Setting Finished Exit from Operation". See the English version of the manual available here: https://www.ustel.com.hk/manual/Uniden/manual_AS7401_EN.pdf . I hope this helps. Cindy Wells

There should be a label on the base unit with the model information.

Something may have failed in the base unit but there could be a telco problem that is cutting off service. If you can substitute a different phone and still don't get a dial tone, contact your telco to find out why.

Clear the Handset's Base Data
  1. To remove the base data from a handset when out of range of the base, press and hold the 'end' button and the '#' button simultaneously until the phone beeps.
  2. It will now be de-registered from the base.
Note: This requires that the base and handset can communicate with each other.

Call the phone provider you are using, (verizon, att, etc.) they can help you to reset the password.

Hello Lynn: Make sure the power cord is securely plugged into the telephone base. Plug the telephone base into a different working electrical outlet not controlled by a wall switch. Move the handset closer to the telephone base. It may be out of range. Reset the telephone base by unplugging the electrical power to the base. Wait for 15 seconds and plug it back in again. Allow up to one minute for the cordless handset and the telephone base to synchronize. Other electronic products such as HAM radios and other DECT phones can cause interference with your cordless phone. Try installing your phone as far away as possible from these types of electronic devices.
