How to erase current greeting and record a new one,the model number on my phone is 27851GE1-B

Call your phone while you're away, and when your message starts to play enter your remote code. After that, you use the keypad on the phone to control message playback, record a new greeting, etc.

"DECT 6.0" is a generic term for the cordless phone technology, and not your phone model number. You'd find that on a label on the back or bottom of the base unit. Without a specific model I can't look for a manual and give details, but if you have the model listed you can download the manual from Panasonic here. It gives all the steps to set up your remote code and the commands to use. If you have a different model phone you can look for your manual at Panasonic's support page.

For the model listed above, the default remote code is 111. The list of remote commands is

Key Remote command
{1} Repeat message
(during playback)*1
{2} Skip message (during
playback)
{4} Play new messages
{5} Play all messages
{6} Play greeting message
{7} Record greeting
message
{9} Stop recording
Stop playback*2
Start voice guidance*3
{0} Turn answering system
off
{*}{4} Erase message
currently playing
{*}{5} Erase all messages
{*}{6} Erase greeting
message (during
greeting message
playback)
{*}{#} End remote operation
(or hang up)

Maybe this list works for your phone too.

Try uplugging the power adapter from the wall and remove all batteries. Wait for three to five minutes before restoring power then batteries.

Try again to erase the greeting.

Go to your personal greeting and press delete twice and press rls this will delete your personal greeting and you can re-record your new personal greeting I hope this helps you!

Hi Sherrie, I am sorry to hear about your husband, I will do what I can to help. I am fairly confident on that model that if you push the greeting button, then delete it will erase the message for good. Also, if the memory power failed, then it would reset to the default greeting and erase all messages and greetings. However, if the unit has options for multiple greetings (ie. default greeting, greeting 1, greeting 2, etc., then perhaps the default greeting may have been selected, while your husbands greeting is still there but is recorded under say greeting number 1. If that is the case, you can select it to play his greeting instead of the default greeting to have it play. I would find out for you but my computer is having trouble opening the manual on the Panasonic site, so here is the link. Look under "greetings" in the index. Hope I helped.
