Uniden FP1355 answer machine does not work if you are on the phone

SOURCE: My new Uniden Phone/Answer machine is loading down my fax line

I have searched the user manual and can find no help on this matter, although there are help numbers listed and I'm sure they can advise, here is the link to the main page and there is a link to a pdf manual download if you don't already have one http://www.uniden.com/products/productdetail.cfm?product=TRU8885-2

However, it may be that you could use a T adaptor or socket doubler on the line jack and plug both in. good luck !

I had the same problem with a Uniden 3355 handset and 2355 base. With the new handset I pressed "Menu" and selected "System Reset". I then Selected "Deregister HS" and followed the prompts.
Once this was complete, I returned to "System Reset" and selected "Replacing Base". Following the prompts, when it said "Register Handset" I put it in the base of the 2355, and within a minute it had registered, so both handsets used the base of the 2355!

The default security code is "80". If you have not reset that code, you will use 80.
This is all from the manual:
1) Call your telephone number and wait for the system to answer. If the answering system is off, it will answer after about ten rings and sounds a series of beeps.
2) During the greeting or the beeps (if answering system is off), press 0 (zero) and enter your security code within 2 seconds.
3) The answering system announces the current time and the number of messages stored in memory. You hear "To play incoming messages, press zero-two. For help, press one-zero" followed by a beep.
Then the manual lists all the remote commands. If you need those, you can go to uniden.com and download a manual.

I have the same handset and the 2nd one seemed to stop working after working great for 2 yrs. I placed both sets together and hit the PAGE button on the main handsets cradle. Both phone's were paged and, for some reason, the 2nd handset reset. It worked for me...or at least, something in what I did worked. BTW, H1 and H2 shows in upper right side (or at least it did after I paged)...and I made sure to put the phones in the correct cradle (H1 is the main handset). I just did this so hoping it continues to work!
