I think this one is right–it turns out that it is the maint. req. light rather than the check engine light. I did look in the owner’s manual prior to putting this post up here. The light did not used to blink at all (but it is normal for all lights to turn on for a moment when I turn on the car), and it does not continue to blink or stay illuminated at all after the ten blinks when I turn on the car. I think I’ve answered all the questions above. I did have the oil changed recently, at a Honda place no less, but it is very possible that they failed to reset the indicator. I’ll try resetting it using your suggestions.
