how to find GE codless phone manual-model#2-9230A

Hi drbwin,

You'll find the manual for the AT&T 9230 cordless phone at
http://telephones.att.com/attui/support/manuals/ManualView.cfm?manualID=230

It's a 25 page PDF file (you'll need the free Adobe PDF Reader to view
it, there is a download link on the page if you don't already have
it).

The section about Clearing Numbers from memory is as follows:
