Brand new C315. Set the admin password successfully during setup. Went to log in after, no luck. Too many attempts - locked out. Tried that a few times without success (once lockout expired). It's possible I made a mistake setting the password, but had to have made the exact mistake twice. Even though that keypad is ridiculously tiny, I think that's doubtful.
Anyway, did a factory reset to original settings, and tried logging in with admin/<serialnumber>. No luck there either - yes I matched the case. "1111" didn't work either.
Any ideas appreciated.
