Ex29382 1a will need the user manual or setting manual, thank you

Hi Wendy - GE writes their numbers differently in "public" than they do when you're looking for something. It looks like your 29382 1a is actually 2-9382, and you can find the manual for that at this link:

They also have links for many other phones and you can download them (or just view them) as PDF's free of charge.
