How to factory reset vtech cs6409 - Uniden DCT-748-4 Telephone

Hi,

Please double check that any battery in the phone has been updated within 3 months.

Vtech also suggests using an outlet not controlled by a switch.

Otherwise, please take time factory reset your Vtech device and check for the error again.

Thank you.

Best thing about this new service is HELP NUMBER +1 833 272 0777that you are never placed on hold and get to talk to real repairmen in the US.

De-register the base station by holding the find handset button for 10 secs ... to reset/deregister a VTech Dect 6.0 handset without the old base

To deregister all handsets, with all handsets in standby, press and hold the Find Handset button on the base for about 10 seconds (or until the In Use light turns on and flashes). Release the Find Handset button. Then press and release the Find Handset button again while the In Use light is blinking. (You have about 5 seconds.) Wait until the process is complete. You should see the registration message on all handsets.

If the deregistration process fails, you can try resetting the unit from a registered handset. Pick up the registered handset that is on the base. Then press Talk/Flash button and then Off/Cancel buttons. Then try again.

The manual for the additional handset, CS6409, that is available for the CS6429 has the de-registration procedure. That manual is available from the product page: http://www.vtechphones.com/products/product_detail/1604 . Click on the Support & Manuals tab. The direct link to the manual is http://cdn-media.vtechphones.com/media/p/document2/products/%7B9B67F082-6CC0-48CC-B7F2-23C65B10A4F1%7D/CS6409_UM_V3_20141202.pdf .

I hope this helps.

The CS6409 is just the handset. The answering machine is part of the base. Enter the model of your base into the box at http://www.vtechphones.com/support/general/manuals to download a copy of the manual.

See page 26 of the manual for detailed instructions on HOW TO REGISTER THE HANDSET TO THE BASE.

Basically, the manual reads as follows:

Not registered appears on the handset and it does not work at all.

The handset may be deregistered from the telephone base.
Follow the steps below to register the handset to the telephone base.

1. Remove the handset from the telephone base.

2. Press and hold FIND HANDSET button on the telephone base for about four seconds until the red IN USE light turns on.

3. Then press # (pound key) on the handset.

It displays Registering... and it takes about 60 seconds to complete the registration.
The handset displays Registered for a few seconds and you hear a confirmation tone when the registration process completes.


I hope that was helpful to you, good luck and take care.
