SOURCE: Wrong Manual Received for CASIO Pathfinder PAS 400B 2632

I was having the same problem, so I went to casio.com and looked for their manuals for watches. I ended up finding this page:

http://world.casio.com/wat/download/en/manual/

If you enter the number from the back case of the watch, (in this case, the PAS 400B is 2632) and it will allow you to download the manual from their archives in a pdf format.

Hope this helps!

SOURCE: casio pathfinder SPF 70-s titanium band adjustment

I purchased a Casio Pathfinder solar/atomic watch, with compass, altimeter, barometer, thermometer, model 1200T-7WC (titanium).
Has the titanium band - on this particular band each link is somewhat waveshaped {i.e., there are 2 "arms" from the link making contact with the middle part of the link above (above meaning towards the watch body), and 1 arm fitting between the 2 arms of the next link down). Unlike described in the first solution, the pin is not split, but solid (doesn't look like a slotted screw on 1 end, so the solution at http://www.wikihow.com/Adjust-a-Casio-S-935L-Watch-Band is no help). Here's what to do if you have this band:

1. Note: before you start, be advised there is a tiny loose 1/8" part (sleeve) that will fall out as you pull the links apart, so work over an appropriate surface to "catch" it. Push pin (from the upper "arrow end) of one of the removeable links (those with the arrows on the backside) out of its hole with a fine poker (I used a 1/32" jeweler's screwdriver, an unbent paperclip would also work, just more likely to bend as you push pin out). This takes some force to do - in my case, after pushing, the pin projected out about 1/2 of it's length, I used needle-nosed pliers to gently pull it out the rest of the way). CAREFUL - once pin is removed and you pull the link away from the one above, a small (1/8") constriction sleeve should fall out of the center arm of the link above. SAVE THIS SLEEVE!

2. Using the same procedure, remove the pin from the bottom end of the link you're removing. again, SAVE THE SLEEVE.

3. to rejoin the band once the link is removed, look at the single/middle "arm" of the upper link, looking for the hole where the pin goes through. One side of the hole should be noticeably larger/wider than the other side - this is where you will place the SLEEVE - I used tweezers, or needle-nosed pliers will work - it will drop into hole. Keep this upright so that sleeve doesn't fall out, and slide the 2 arms of the lower link in place around the center arm.

4. Slide the pin you removed into one of the outer link arm holes - I found it easier if I started from below, pushing it into the center arm - it will stop when it reaches that 1/8" constriction sleeve. I set the extruded end on the pin on a magazine (i.e., slightly padded surface) and then pushed the top side of the band down, forcing the pin through the constriction sleeve and up into the upper arm hole, and Voila, your band is reconnected. The sleeve is important (without the sleeve in place, the pin will simply fall back out).

SOURCE: Casio 1170 ATC-1200 watch needs to have batteries changed

I'll post in case somebody still needs this. This is the general procedure to switch the ATC 1200 from meters to feet. You can also switch the ATC 1200 (1170) from C to F. This is very helpful if you change the batteries and the watch gets reset to meters.

Also note, when you pull out the two batteries, you may not get the watch to come up. This is because of a race condition when the watch gets power. To fix this, look for the AC mark on the inside of the watch. Under this marking, in a little space to the left, are two copper pads. Short this out with a small screw driver to get the watch to ground zero.

To fix the Metric measurements:

1. Go to the home screen on the watch. This is when the the 3 letter abbr for the day is at the top. Also, if you cycle the mode button, it is the screen where the final beep is "high."

2. Then press the "memory" button, which will take the home display to the data screen. This shows current time, pressure and temperature.

3. Hold down the adjust button, until the set screen comes up.

4. Tab the mode/select button on the watch until you get a flashing C. Then press the memory button to toggle to F.

You can adjust all the measurements from this screen.
