How do you put the back, back onto this fs1? The band keeps getting in the way! Back came off easily enough, popped off after unscrewed. Band is still on watch, have tried to slide back into grooves but just does not fit, keeps popping up on one end. Any solution? Can this band be removed and put back on?

As far as links go only the manufacturer would carry them. However a replacement band can be easily installed and can be purchased at your local Wal-Mart. You need to measure how wide the band is where it connects to the watch in MM (most bands have a width that is uniform however I've seen some before that get smaller as you move away from the head). The band is held onto the head by a part known as a spring bar. In order to remove the band get something small like a dental pick (that's what I use) and push the bar in while at the same time pulling on the band. If you don't pull the spring bar will reengage and snap back in. Removing the band is fairly simple however the trick is getting them back in. I line the spring bar over the natch and try to get one side in at a time although on some watches both sides of the bar must be pressed in at the same time before the band will fit in the slot. It really just takes patients and a steady hand.

send your watch to an Authorized Polar Service Center, these are not designed to be user serviceable.

You can get a copy of the user manual by going to their web site- link http://www.polarusa.com/us-en/support/downloads?product=&category=User+manuals.

Fill in your model name and download.

On my tips and tricks page is a link to the user manual.

The trick with the FS1 is that you have to wait between button pushes. Don't try to skip ahead of the pace of the watch, it is slow to set anything. That is the rub with 1 button operations.

Push the button, wait for the prompt, enter the info, push the button, wait for the prompt, etc.

if after trying this it still doesn't work you will either need to take it back and exchange or send into polar. There is a warranty service available. Again that link is under my tips and tricks.

Here is a video that shows the entire process of replacing the battery in the Polar fs1. It shows the little plate and where to place it.

Hello
You can change the battery in your polar f7 if the battery is worn out.
1. Insert the tip of a pen knife into the lifting point and lifting the back up. The back of the watch is only pressed into place and will come off easily this way.
2. Grab the small clip that is extending across the surface of the battery with a pair of tweezers. Slide the tweezers toward the end that hooks down into the watch. Pull the hook end of the clip out of the watch and remove the clip from the battery

3. Match the old battery with a new one at any electronic store. The store will be able to read the writing imprinted on the battery to make sure that you get the correct battery type for your heart monitor.

4. Press the new battery into the watch making sure that the writing on the battery is facing up.

5. Press the holding clip back into place. Handle the clip with tweezers only, since it is very thin and can be bent or lost easily. Once it is in place, press the back of the watch on.
GOODLUCK

mcdevito75 here, It"s areal pain but you just have to hang in and keep trying. Postion the band and pins as you can for easy assembly. If you give up see a small watch repair shop in your area, take a break while trying to fit the band if you get aggrivated.

If you go to http://www.polarusa.com/us-en/support/downloads?product=&category=User+manuals

You will see a drop down list. Scroll down to find the instructions for your model.

Like most makers, they recommend that you have batteries changed at one of there service centers (to retain the waterproof seal.

Some people have problems when refitting the backs of watches and come onto this site to find out how they can get their watch going again. The cost saving does not seem worth the risk of damaging your watch. If your watch is still under warranty, then it will be invalidated by unauthorised repairs.

To find your near service center, go to Ploar.com and click on "support" and then "service" and "retail finder.

The plastic wrist band doesn't have to be cut away. You need to dislodge the spring-loaded end of the pin from the hole in the plastic with the blade of a sharp thin knife.

The you proceed to lift one of the 4 snaps to open the cover. The battery is under a white translucent inside cover.

The original battery was Sony SR621SW.

Pay attention to the rubber seal ring when putting the watch back together.
