Come on man, what if the OP purchased the car used, and did not receive
an owner's manual?

Then again this might work too:  With the key off, hold down the trip
meter reset button. turn the key on and continue holding the reset
button in until the maintenance light goes off, about 10 seconds.

do you have the Operators Manual? it probably has the info you seek.

'98 Accord

I just brought it back from the dealer and the Maint. Req'd light is on.  It
wasn't when I took it there for radiator/coolant service.   I read somewhere
that the light isn't related to any type of service, it's just a reminder
light that needs to be reset.

I'm not happy with my dealer at all and don't want  to have to be without my
car for 24 hrs just to have the light reset.

I saw something recently that said to turn the key to the on position, press
the pedal to the floor three times within 7 secs, then turn to the off
position and start normally.  It said the light should go off in a few secs.
I tried it, it seemed to go off for 1 sec and come back on.  Tried it a few
times, same result.  The article said to keep trying if it didn't work on
the first try.

Am I doing it right or wasting my time?  I just need to reset the Maint
Req'd light without having to make a service appt a week from now and be
without my car again.
