For all Casio watches go to select "Support" then "Manuals" then "Watches".
You will then be able to enter the 4 digit number in the square box to get the manual for your watch or module inside is actually what the instructions refer to.

The silver spring goes in a very small hole in the plastic casing on the bottom side of the watch located next to the wristband under the sensor. Hope this helps

If you look very closely you will see that one side of the clip goes nearly under the battery. the plastic there has what looks like a small hole near the metal. It is in fact a slot. use a straight pin inserting it in the slot and gently moving the clip away from the battery. There is bend tension on the clip and it should raise slightly when released. Then use a tweezer grab the battery.

use your tweezer to hook the clip back over th plastic after you insert 4 new batteries.

i had this problem with mine after a battery replacement. If you open your watch, and look behind the offending button, you'll notice there is a small arm that should fit behind the button. the jeweler that destroyed my O-ring during a battery replacement also failed to line these arms up on one side of the unit. i had to find a REALLY small screw driver and finagle the arm back under the button... Now it's working perfectly... except the whole not waterproof any more part....

Hope this helps.

If you look at the GMT differential in the manual, you'll notice that it corresponds to the offset from GMT that your time zone resides in. I live in San Antonio but i don't see that on the list. I do know that when we're not in Daylight savings time, I'm -6.0 from GMT... so that's what i set it for. Also, if you're near enough to the coast to use this feature, it would probably be a good idea to compare the watch reading to the actual tides and adjust accordingly.

Hope this helps.

"AC" means All Clear. This terminal should be marked somehow. Use a magnifying glass to get a good look at what you are working on. My Casio had an arrow pointing to four copper leads. I used a paper clip to connect the AC terminal (I just picked one of the four) to the + side (usually the "up" side) for a couple seconds and my Casio Sea Pathfinder model 2273 powered right up. See the following link for more guidance.

The screen may be damaged. Or just faulty. If it had to go through too much shock, its trash.

Your Watch is in Auto or demo mode. Hold down the "Mode" button for 3 - 5 seconds and it will return to time keeping mode.

Call the repairs center at 800-706-2534 and then keep choosing option 1. Tell them what's going on and that you would like to send it in for repairs. If they ask just lie and tell them you already talked to tech support. LOL

The format (12-hour and 24-hour) of the alarm time matches the format you select for normal timekeeping. When setting the alarm time using the 12-hour format, take care to set the time correctly as morning or afternoon.
