You can get instructions by going to http://www.sportline.com/category.php?cat=4
and locate your watch from the list and clicking on your model.

Now click on "more info" and you will find a tab marked "manual"

just bring it to the authorized retailer of your watch because they really know ho to change your watch battery

Press "MODE" and above it "SET" and it should help you re-set the time correctly.Hope this helps!

I'd not advise to do that, but if you want to do it yourself, follow this: Open the watch case back, undo the battery contacts, memorize battery polarity, memorize all the writings on battery, buy exactly the same one and repeat all actions in reverse.

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.

pulse reader will not work after battery change

Electronic Tech for Government & the last thing you want to do is try to fix it yourself. The watch is a dual unit with the power supply (battery) encased by plastic & a steel unit case wrapping itself around that. To complicate things there are two circuits connecting pad (sensing unit) built THRU the power unit (as springs). There is a rubber piece that makes the circuit for pulse mode from the case to the watch & that is tricky to place for sensing unit to work (the whole purpose of having this sport watch). Replaced mine for $4 but it was a surprise to find it THAT complicated.
