Here's what others have to say...

Write your question here...How can I get a replacement transmitter? I lost mine in a move, so now I have a perfectly fine watch but no transmitter.

You will have to contact Polar and buy a replacement. Go here:


Good basic unit for starters.

    Around 110 bucks. Memorizes the last workout recorded. Keeps lap times. Reset-able count and calories totals. Makes working out a lot more fun.

    I see that the coded transmitter is included, but doesn't mention the chest strap. Is the chest strap included or purchased separately?

    does the polar rs100 heart rate monitor have a user replaceable battery for the wristwatch or the chest strap

    No and it's not easily replaceable I recommended when the battery has run out; contact the authorized Polar Service Center in your area.

    You may be able to get the back off of the wrist unit to change the battery. I was. However, the waterproof-ness of the unit might be compromised. The transmitter battery is potted in. When it goes dead, the transmitter is useless and you can throw it away. There is another transmitter available that has replaceable battery and will work with your RS100. It is called a "wear link" transmitter.

    My daughter in-law had a battery store change hers but Ryan is correct, if you do not send it to Polar the warranty is void if that really matters.

    Is there a way to upload workouts onto the polar personal trainer website with the rs 100?

    make notes, enter data, target workouts by typing them in in "diary" once you register. It's easy, I do it every session.

    does this come with the coded transmitter and how do you upload to a computer/ where do you buy the extra to upload?

    The coded T31 transmitter is included, as stated in the specs above.The way the watch and computer talk is called Uplink. It is software that utilizes the computer's sound card and speakers to facilitate communication. Generally the speakers that are found on laptops do not work.I used it with success on an older Polar watch with separate desktop speakers.

    Is this watch going to fit me? I`m a slim, athletic woman.

    Unless you're a slim, athletic woman with really fat wrists, you should be set.
