Casio PRG-80L reads open

Have the same problem, Casio PRG-80L reads open. No hints about this in the manual. Nor did Votit's suggestion help. Note that although the watch is old there is clearly power left in the capacitor battery. Ended up accidently ito this mode when resetting the time. Assume the open mode is intended for service, but would just like to exit.

Casio PRO TREK error 'OP EN' Display frozen with the above msg. None of the buttons - except the light - works. Whats wrong .. battery charge shows FULL

The problems is very simple: On the back cover (inside) is a little Cu metal Part. This part is glued to back cover using a poor glue (rubbered glue) and, in time, is moving from original position. You must put back this parts to original positin ( a little hole inside of back cover) and glue using a good glue. When the back cover is mounted , this part must have a ferm contact with two springs from mechanism (sensor for back cover open). If beatwin this springs isn't a electric short (using Cu metal parts) the internal mechanism of watch "see" the back cover is open and show "OPEN" on screen!

I have a Casio Pathfinder PAG-70 that reads "OPEN" on the display where the date should be. It is a solar powered watch and shouldn't need a battery change. Any ideas?

Alti does not read correct alti.

Don't forget that the altimeter is barometric, and therefore the altitude reading will change depending on the air pressure - i.e. the weatherman may give the 'high pressure coming through' or that there is a low pressure giving rain - to get the true altitude, you need to know the true air pressure at any given point on the earth ~(where you are) then set this as the 'normal'. you will then get the correct altitude. Don't forget that if you are in a pressurised aircraft - as in allcommercial flights, the cabin air pressure is artificially kept at appx 4000-6000ft altitude

Casio pro-trek PRG-60T Buttons no longer activate anything.

Send it into repairs and they will send you an estimate on what it would cost to fix it. Give them a call at 800-706-2534 option 2.
