SOURCE: Handset can't find base.
I just got a 3rd handset for the same phone system and were having the same error message,,, the at&t help line does not know what it is,.,. We returned it once and got another one because of the same problems, and were still having it.. AT & T help line said to return it again and try another one .. then he actually said to replace the whole phone system .. thats easier said than done! we paid 199 plus tax on the system and then another 81.00 for the third handset!

Rosehello's solution worked with one additional step for my handsets...After re-programming all of the 4 handsets, I had to unplug the base unit one more time and then it reset. Until that time it would only show"AL" and would not function.
