In checking out information about my new S7 ECG Heart Rate Watch, I noticed your posting. There is a Sportline website that enables you to down the product manual.... although I'm not sure it pertains to the S7. If this doesn't work, I'm sure there is a manual included with the watch I just received, and I'd be happy to email to you. I'll check back to see if you've posted a response here to see if the below website worked for you first.
