If you bought it used, you need to call the person who you bought the unit from and tell them to delete their registration so that you can re-register under your name. If you bought it new, call Garmin customer service at 1-800-800-1012 and have them clear the registration. They will require proof of purchase. New Units sometimes get purchased registered and then returned. Some places will place the merchandise back on the shelf after verifying everything is still there.

Short answer:
No. This model of phone can only support 4 handsets. If you need more than that, you will need to have a second base unit.

Detailed answer:
One of my handsets went bad, and I just bought complete DCT748-4 package from a seller on eBay for a very good price. This set was used, but in very good condition. I didn't need the whole set - just one handset - but like I said, it was a good price. Anyway, I began by telling my old base unit to de-register handset #2 (the failed unit). However, I then found that I could not register the "new" handset with my old base unit because it was already registered to the "new" base unit. So, I first had to apply power to the "new" base unit and de-register the handsets. Then, I placed one of the "new" handsets onto my old base unit, and it said "Handset Registering ..." and registered just fine. Just for the fun of it, I placed one of the other spare handsets into my old base unit. It said "Hanset Registering ..." but then it beeped and said "Registration Failed." This is because I already had 4 handsets registered to my base, and the base can not handle a fifth handset.

I returned he item to the store and got my money back.
