That's interesting. I work around the corner from the store I purchased my
DCM315. I bought it during lunch and took it back to the shop and examined
it. I noted that it appeared to have been used although the seal was intact.
The power cube was rated 12 v. I took it back and got another one. When I
opened it up, I noted the power cube was rated at 9v, 800ma. I looked for
the specs in the book and on the modem case and didn't find any. I wonder
what the power requirements really are?
