Searching for base

I have some handsets I purchased on ebay which I'm trying to get to register to the base at my home. I can't seem to get these to unregister from the 'former' base they hold in memory. Does anyone know how to reset these, can you just take the battery out for a week or two and pray it loses the old Base ID? Thanks.

This might sound silly, but have you tried plugging another phone into the wall jack to make sure it works?

Uniden dwx207


When a handset is reading "Searching", it can't communicate with the base. First, check if the base station is plugged into a live outlet. (Try plugging the base into a different outlet or making sure that the circuit breaker hasn't popped. I had a cordless phone base plugged into a UPS. During an extended power outage, the UPS was turned off. The phone didn't work until someone noticed and turned the UPS back on.) Move closer to the base station.

If this was an extra handset purchased later, make sure it is compatible with the base station. The Uniden DWX207 works with the DECT1500, DECT2000 and DECT3000 series bases. Register the handset with the base. The registration procedure depends on the base station. If the base unit has an LCD screen, with the phone in standby, press Menu/Select and press the down arrow to reach "Register Handset". Then press Menu Select again. (If the base doesn't have an LCD screen, unplug the power cord. Then hold the Find HS or Find button as you reconnect the power cord until the Charge/In Use light starts to blink.) Then press the # key on the handset before the registration period ends.

Make sure that you haven't exceeded the number of handsets for your base. You may need to de-register all handsets and then re-register them.

If no handsets will pair with the base, replace the base unit. The transmitter or the receiver aren't communicating properly with the handsets.

I hope this helps.

Handset won't work


I went through this exercise with a Siemens Gigaset 8800. The solution is to DE-register the handset first. Then register it with your base. This function can likely be accessed in the handset menu. The phone you purchased is apparently still registered to the previous user's base.

Trying to register used handsets


There are a couple of things that may be the problem with this. First, are you sure that the handsets are compatable with the base you are trying to register them to? Second, how many handsets are currently registered to the base unit? You may be trying to register more handsets than the base can handle. and lastly, try doind the de-registration of the handset this way, press and hold the "End" key, while pressing the "End" key, also press the "#" key. The lcd should show two options, select "Base Unavailible" and confirm. The LCD on the handset should then say to place it in the base to register it. If that doesn't work, post with the results of trying the above steps and I will try to help you further.

You may need to register your handset to the base.
Normally ,there is a advanced setting ,register handset. At the same time, press and hold "page" key on your base 4 to 5 second , there is be a registation success tone from handset. You can register all of your handset ,one by one. Some model need to input register code, normally ,it is 1234 , or 0000.

VT2461 ADDITIONAL HANDSET PROBLEM


I can vouch for the second solution. It worked perfectly on my 2461 with two extensions. Even the vTech website was not able to provide a solution.

Searching for base


My long-term experience with these phones is that occasionally, they get themselves into some kind of weird state: this is usually indicated by the flashing "searching" message.

In all cases it's been cured by unplugging the power supply AND the phone-line (both simultaneously) from the base, waiting a few seconds, then re-connecting. Normally this sorts things out, but will require you to re-set time& date (the base can sometimes still derive power from the incoming 50v line). Batteries out of handsets is a last (addtional) resort. I've very rarely had to re-register.
