As long as your expansion handset is running on the same frequency as your primary handset, your problem is most likely that your expansion handset needs to be "mated" back to your primary base unit. Try removing and then replacing the battery, and then placing your expansion unit on the primary "home-base" charger. If that does not fix the issue, then you most likely have a faulty handset and will have to exchange it for a new one or send that one in for repair, depending on how long age you purchased it and how long your warranty is good for. Anyways, I hope this helps get you back to talking!
Have a nice day!

My vtech dect 6.0 keeps saying unable to call try again


I had this happen suddenly on 2 out of 3 handsets with a DS6151 base and DS6101 handsets. Well, what happened is there was no dial tone on either of the 2 handsets on either of the 2 lines and a message appeared on the display "Unable to Call Try Again" after some delay, if Line1 or Line2 button was pressed.

Oddly, the 2 that did not work were the ones normally on "extension" chargers and the 1 that did work was the one on the base unit. That caused me to suspect the base unit .. which it still may have been but the solution was NOT. And, also odd, the handsets seemed to still be synched with the base unit in many respects.

Cycling the power on the base unit did nothing.
These are fairly new units and battery life is generally much longer in my experience.

The Solution:
- Remove the battery from the handset that doesn't work properly.
- Re-install the same battery.
Whatever was wrong, this reset it and the handsets started working again.
Easy fix.

I bought a cordless uniden phone DCX 640 on craigslist. it came with an extra handset. My problem is that there is no owner's manual so I don't know how to use the many buttons on the phone base. ...


Your phone's owner manual can be downloaded from this location.
Hope you are able to sort your problems out soon.
Anyway, please, let me know if I can help you out any further.
Regards, Carlos

Phone continues to display "welcome please wait..." I can't turn it off and I get no dial tone.


I have found this is cause by one of two problems: 1) the transfer button has been hit and it is waiting for anther unit to pick up. 2) (and most likely the problem) the battery is low on charge.
with case number 2 if your battery is at the end of it's life it will only keep a charge for a short time. it might even say it has a full charge but it does not. I have tested this out by switching the battery and then finding that the handset works fine. I hope this helps you.

Phone says ''Welcome ... please wait'' when you try to use it


Hi,

I tried to copy and paste the solution for this issue, but Fixya only allows so many charecters and I guess the answer is too long.
Go to http://www.uniden.com/index/manuals_results.cfm?cat=1

and select the owner's manual for your model phone. Follow the procedures for deregistering the handsets and then resetting the base. then re-register the handsets and you should be good to go. It is all pretty easy, just a little to wordy for this forum I guess.

Uniden DSS7855+1, flashing ''welcome! please wait...'', wont work


This is not a direct solution to your problem, but a workaround for a similar situation. I have two headsets and two charging stations. One of the headsets was stuck with the message ''Welcome! please wait''. When I put the phone on the charging station it usually sits on nothing would happen, but when I put it on the other station the phone came back to life. The non-working charging station will still charge the phone so it is worth keeping.

My phone keeps saying unable to connect


is your phone about a year old? It may be the battery. The vtech phones have weak batteries that clunk out after about a year and you'll get dropped calls, looking for base etc... The phone still appears to be working and the battery indicator tells you it's charged, but the battery is too weak to keep the wireless connection going.

Had the same problem and replaced the battery. budgetbatteries.com had the cheapest ones. But it's a knockoff, so I don't know how long it will last. So far it's been 3 months and the problems are gone. I would try that first and see how it goes. I paid about $15 including shipping. If you buy it from vtech it's at least double...

UNIDEN DWX207 SERIES ITS WATERPROOF


Same thing was happening to my phone...Welcome! Please wait... After at least 40 hours of charging I was getting a little fed up. I picked up the handset, took a ball point pen and pushed the "activation" area on the bottom the phone...heard a click...now it is working. I don't think the tiny pin that comes with the phone activates the phone properly.

Extra handsets no longer seem to work. No ring and no line


Please be sure to put the extra handsets in the MAIN base station to register. They will not register in the small remote charger stations.

Let me know if that fixes the problem!

Handset Fails to Register


It is quite possible that you'll need to go into the menu settings on your base-unit and reset the unit or restore factory default, whichever option it gives you. Also, look in the menu on the phone to see if there is an option to reset the handset also. After resetting the unit and/or handsets, try to register the handsets again, one at a time. If that still does not fix the problem, you may have handsets that are not compatible with your system, or your system may not be able to support that many phones. However, if you have the right handsets, and your system can host that many handsets, then I'm confident that resetting the unit and re-registering your handsets should fix your problem.
Hope this helps! Have a nice day!
