HOW TO CHANGE THE BATTERY ON A Dakota Tough Compass Clip Watch

Hi john30x,

You have to calibrate the compass.
1. Press the upper right button (switching to compass mode)
2. Press and hold upper left button. The "CALL" will appear on the display. You are in compass calibrating mode.
3. Rotate the watch horizontally (around his vertical axis) slowly, so to be sure that he point the North at least 2 times.
4. Now press the upper left button again to input the declination (this is the angle between the magnetic and real pole). It is different for the area around the world, that you want to explore.
5. Switch between the positions of the cipher by pressing bottom left.
6. Change the cipher by pressing bottom right.
7. Switch between the active position by pressing bottom left. Now you have to enter East or West declination
8. If you are ready press the upper left. "END" of calibration will appear on the screen

Once you calibrate and set the declination you can use the the compass by pressing upper right button. As the compass is very sensitive It is good idea to calibrate it on a field, far away of metal objects and electromagnetic fields (cables, ect.). You need to calibrate the compass each time you want to use it by different surrounding.

Remember the compass function of your watch need much more energy than the watch itself. Don`t worry to change the battery when dead. The water resistance remains good even after. Very robust and accurate device. I hope that should help.

If you don't already know what size battery you need, you can find this information on the back plate of your watch. Once you have your replacement battery, you will need to open the back of the watch to gain access to the battery compartment. Depending on the watch, the back plate will either screw off or be attached by a few small screws. If attached with screws, you will need a set of precision screwdrivers such as a jewelry or eyeglass kit.

Inside the battery compartment, you will see the battery is held down by a clip. Carefully remove the clip and eject the battery. Insert the new battery and replace the clip. If the battery clamp indicates you should do so, quickly press the reset button twice. Then reattach the back of the watch. If the watch display remains off after replacing the battery, press all buttons at the same time to reset the display.

I took a clip watch to the Mall today and had the battery replaced at the Dakota Kiosk. It cost $10. They used a tiny knife to pry off the back. I was trying to use a screwdriver and that didn't work.

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

I contacted the manufacturer. You remove the crown, then use tiny attachment to a bike pump to push air into the interior of the watch. This will cause the crystal and dial to come apart. Viola!
