Systematic diagram of MB685019 omron model - Omron Hj 720ITC Advanced Pocket Pedometer

Perhaps contact Omron for assistance.

Unclear if you want to simply merge 2 CSC files on a computer or somehow on the HJ-720ITC

(Also, is that an I or a 1 in the model name?)

Contact Omron through the internet:

Here is the official site for Omron manuals:
http://www.omron-healthcare.com/eu/en/support/manual

The manual for that model is one of the skimpiest manuals I've ever seen!!

Contact Omron... they do not recommend that timer replacement

Why do you want to change it from Metric to Imperial? Omron Pedometer works really fine and I don't think there's any need to change it.

This website has the instruction manual for the Omron pedometer. It may not be the exact same model as yours but it will still help. I just changed my batteries and have a different model which has the reset button on the back. Still, the basic stuff is there and I was able to re enter all info. Hope this helped.
