- you don't hear a dial tone- the display says Registration Failed
Making sure the handset is fully charged, then start over at step 1.
To register a handset to a different base, see the section "Expanding Your phone" in the user's guide for the other base.

Have you tried charging (which will reset the handset) in the base charger as opposed to a remote charger? Have you tried moving handset #2 around the house in case the problem is related to interference?

The handset for this unit registers automatically to the base. The main base sync with the handset but it does not respond. The handset that is not responding has a problem and should to be replaced. You can pick one up on eBay for a few bucks.

The battery in the handset could be bad . First I would test that the base unit is recieving dial tone by pressing speaker button on base unit. If there is dial tone then problem is in handset or in base unit communication to handset. Try resetting power to base unit. Check manual for any re-initialization procedure. If the base unit is not receiving dial tone then I would test that the phone line is delivering dial tone to the base unit by connecting a known good phone to the line cord. If the dial tone is not present , problem could be in line cord from outlet, outlet, building wiring, or service provider.

Check the Battery on the Handset. remove the pwr frm the base unit n connect aft 30 sec. aft this if it still says the same msg, then the handset needs to be replaced.

hold the select button down a few seconds until you'll see a 'tn' on the readout. this sets it to tone. hold it down again and it will set back to 'Pu' for pulse. i figured this out by accident. the losers at vtech never answered my question.

I was having the same problem with the same model phone, and fixed the problem by rebooting the phone – unplugging the AC and phone cord from the base station and plugging both back it, then removing and replacing the handset to regenerate the security code.

I have the problem. I think it is because the battery i have in it was a Ni-MH and it should be a Ni-Cd. I am now looking for the right baterry Good luck Frank [email protected]

2/29 Have you registered or re-registered the handset?
"No link" can mean handset is not accepting radio wave of base unit. At Mfgr website pull-down operator's manual and look for registration instructions. Some sequence of buttons will create a radio signal from base (have handset off base) then another sequence of buttons on handset will accept radio signal. If handset has "menu" button, try "menu", then "00" (zero zero) then select an accept or "OK" button. Good luck.
