mcdevito75 here, I see in your question, SOLAR if that means the watch is operated from the sun"s energy, you first have to get the watch going (ticking) before you can set the time, Instead of a Battery your watch has a capacitor that holds onto the sun"s energy and releases it, makeing the watch go (tick). After the watch goes, you need worry about 2 buttons, MODE & SET. Press MODE and see display Flashing, now press set to set each function, (hour, minute etc.) presss MODE after ecah function is set to move on, once all functions are set, press MODE for steady display, also if thew watch is new, look for a small piece of plastic just under the crown, remove that plastic and push crown down to start watch. Hope this helps.

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. Posted 7/11/2010 by Mary G.

On the C9 Fast Wrap Strap digital watch, press and hold the "LAP/RST" button until the display shows "SET" then release. Use the "MODE" button to switch between second, minute, hour, etc. Use the "ST/STP" button to change. Press and release the "LAP/RST" button to exit. The Sportline might be the same or similar.

For instructions, go to "www.sportline.com" where you will find their product range illustrated.

Click on "learn more" for the watch you have and the next page will have a tab with "manual". Download the file.

pulse reader will not work after battery change

With the watch in time mode, press and hold the mode button for 4 to 5 seconds until it beeps and the digits start to blink. Then press the mode button again to advance through each setting. When finished press and hold the mode button to exit the setting mode.

Love my watch, Was placing it on wrist, time correct, pressed button to test pulse and everything went blank. Pressed reset button, with no effect. It has a high pitched whine when placed at ear.
Does this mean I need a new battery, and where is that done, so I don't mess it up.
Appreciate any help as I don't have the instruction book either,
