My casio 3157 watch, compass keeps saying error after I calibrate it? How can I fix it?

THe PRO-TREK watch compass is very sensitive to nearby Iron (eg. cars, fridges, steamships, artillary canons, battering rams, guillotines, etc) and anything wearable or embedded in your body. I had to calibrate mine in the middle of a baseball field.

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.

As a pure shot in the dark, are you sure that you calibrated it so that it was pointing to the north when it should be and not to south?

If it was pointing south instead of north, then East and West would be reversed.

Sounds a bit daft but better than the directions of east and west changing?

Check your calibration perhaps?

Try to reset the watch.But first be sure that you capable of doing this.
Reseting the watch procedure:
1)Remove the back cover.Be sure that you have the appropriate screwdriver.Keep the 4 screws safe, not to loose them.
2)On the chassis of the watch (metallic surface) somewhere there is a hole with AC (All Clear) written nearby.
3)Use one little thin retracted paper clip (not totally retracted).Insert the retracted end of the clip into the hole, gently, until it touches the end and with the upper part of the clip contact the chassis (metallic surface). Wait for 1-2 sec and remove the clip gently.The watch is now reset.All functions have been set to factory settings.
4)Put back in place and with caution the back cover, respecting right (up-down) positioning and taking care that the O-ring gasket is well in place,first.
5)Holding in place with one finger the back cover,screw back screws gently and without applying excessive force (delicate job) until you meet resistance, in the following order:
Up-right,down-left,up-left,down-right.
After setting the time/day/date etc try to calibrate compass both ways as you did before.
I hope this will solve your problem.
NOTE:Again,be absolutely sure that you are capable of doing this.
It is a bit delicate job.If not,you better bring the watch to an official CASIO service center.

Write down the four-digit module number from the watch back, and go to this link for full info in PDF format:

Good luck, Bill

after calibrate sensor display numeral are blank

Here is the manual for your watch. It tells you how to calibrate the compass. Print out the manual and keep for future reference.

Good luck. Did this help you?

Mine does the same!

Above link no longer valid. Here's the current one:

Also, the key was inputting the correct #, in this case 3157 - NOT the 100B - at the following page:

I had almost given up when I looked again at the back of my watch and found the other number.

find your watch and use the manual. if there is no solution then take it in for repair. any Casio retailer should have repair center information.
