Mine cannot transmit either, i'm gonna pull it up and see, but you just have to put it on the base for a few minutes to register.

The display only shows bars. Is my phone on the way out? It will be 5 yrs old in June. It is a 2.4 digital expandable system, model # DCT 6485.

sorry but i think it is time for you to get a new phone. Most phones these days are 5.8 or 6.0, which is much better than your 2.4. A new phone would mean better reception, more clarity, etc. They're always on sale at radioshack

Hope this helps! please rate how i did

Can I use handsets from another DCT 748 unit to expand my DCT 748

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.

Handheld won't communicate with the base

i have the same problem and it has happened infrequently several times. you probably have to deregister the handset and re-register it and rest the base and handheld to communicate since my model is different from yours there may be differences in how to go about it but for my model the suggestion is as follows:

DCT Series Multi Handset Phone - reset to have base and handsets communicate

I have a DCT Series Multi Handset phone and one or more of the handsets is not working, what should I do?
Try resetting the phone system by using the following steps:

1) Enter the "System Reset" menu, then "Deregister HS" submenu.
2) Press volume/up or down arrow keys to select the handset ID to be de-registered from the list, then press the OK soft key.
3) Press the OK soft key. You will hear a confirmation tone. When de-registration is complete, "Deregistration Complete" appears.

4) After de-registering the handset, move to "Replacing the Base Setting" below. When you go through the deregister procedure if you get "out of range", That is okay. Go ahead and go to the next step.

Replacing the Base Setting
1) Enter the "System Reset" menu, then "Replacing Base" submenu. "Do you want to replace Base?" appears.

2) Press the OK soft key. You will hear a conformation tone. The base information will be deleted. When replacing the base is complete, "Please Register" appears, register the handset to the new base.

If your handset is reading out of range. Check the the main base and make sure you unit has power. This can be done by placing the handset in the main base to see if the charge in use light comes on.
If your main base isn't getting power please make sure the ac adapter is plugged in and is warm to the touch. If not the ac adapter would be damaged.
To resolve out of range follow the below steps.
Press and hold the end key.
Press and hold the # key.

Release the keys and select replacing base and press select.
You will see Replace base?
Select Yes and press select.
Now place the handset on the base and it should register to the base and allow for calls to be made.

How does one get the handsets to record the new speed dial numbers on the base phone?

I'm pretty sure the speed dial numbers are programmed on a per-phone basis. Most people would not want changes on one phone's speed dial to effect the other phones. I know registering the handsets will not make a difference. If the cordless phone is working, it's registered to the base. This is required so your neighbor cannot buy the same phone model and use your phone line. In the old days cordless phones were permanently linked to one base but now you can get extra handsets on many systems and "register" the phone to work on your base.
