How do I get back to regular time. All of a sudden, a few months ago - Bam, I'm getting military time. Can't change it using the Date and Time on Menu. Also, trying to change my OGM, and all I get is Memory Full - How do I erase/delete old OGM's. No explanation in the Motorola manual AND ABSOLUTELY NO HELP FROM THEM, nor Radio Shack, etc. Will never purchase a Motorola again. It's a 4-5 year old Cordless MD490. Perhaps, the military time came via my Comcast voice mail. I just don't know. Hate it. I don't want to calculate what time my call came in, and I desperately need to change my greeting. Stymied.
