Question about Watches

Open Question

CASIO DB-E30 battery cover says "after battery replacement contact AC with (-) using tweezers" There is the letters "AC" stamped on the metal shield adjacent to a hole and there is a "(-)" symbol stamped on the metal shield. Am I correct in thinking I short whatever is at the bottom of the hole to the metal shield? I would have thought it would be hard to do that with tweezers! Thanks, Geoff.

"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.

Do not lay the tweezers across any contacts as you may damage the watch.
First you need to examine your watch movement and find an AC point (contact). It is embedded on movement. Use an eyeglass, as the writings can be very tiny.
When found, touch an AC point with one arm of tweezers and battery+ with another arm simultaneously.
Some watches needs to do that twice, so, to be sure, do that twice.
If you are not comfortable with tweezers, you can use a thin wire, connecting one end of the wire to AC point and another to battery+.
Each shortcut should last for 3 seconds.

My instructions on the inside of the case state: "After battery replacement contact AC with battery (+) using tweezers." What does this mean and what is the "AC"


If you look closely at the chassis of the watch, you should see the letters "AC" stamped next to the battery.

The instruction means connect the battery case to this. (I think that tweezers are quoted since they are the most likely thing that users will have to hand).

How di i change the batteries in my Casio Pathfinder 2782


  • Choose a quiet, well-lit room where you can replace the battery in your Casio Pathfinder watch. Prepare a table, desk or other clean, flat surface where you can perform your watch repair. Put down a soft cloth or piece of craft felt to protect the face of your Casio Pathfinder watch from being scratched during the battery installation process.

  • 2

    Set your Casio Pathfinder watch face-down on the soft cloth or craft felt. Use an optical-sized Philips screwdriver to remove the four screws that secure the watch back to the body of the watch. Set the screws aside, but don't lift the watch back.

  • 3

    Slide the watch back off of the body of the watch very slowly. There are three important springs held underneath the watch back; it is essential to remove the watch back slowly to avoid losing them.

  • 4

    Lift the three springs out of your Casio Pathfinder watch using a small pair of metal tweezers. Take note of the length and placement of the springs as you remove them. Set the springs aside with the other disassembled watch components.

  • 5

    Take the black rubber protective disk out of your Casio Pathfinder to reveal an identically-shaped white plastic disk. Remove the white plastic disk and set it and the black rubber disk aside. Use your metal tweezers, if necessary, to lift out the rubber and plastic disks.

  • 6

    Release the battery strap that holds the battery in place in your Casio Pathfinder watch by pushing the battery strap latch to the left. Remove the old battery from your Casio Pathfinder using a pair of small plastic tweezers.

  • 7

    Pick up your replacement watch battery with the small plastic tweezers and insert it into the battery compartment of your Casio Pathfinder watch. Replace the battery strap and push it gently with the tip of your plastic tweezers to snap the latch in place.

  • 8

    Touch the "-" and "AC" terminals on your Casio Pathfinder watch with the tips of your metal tweezers for at least two seconds. This helps ensure that your watch will work properly once reassembled.

  • 9

    Put your Casio Pathfinder back together to complete the new battery installation. Start by replacing the white plastic disk, followed by the protective black rubber disk. Use your small metal tweezers to replace the small watch springs in their correct locations. Replace the back cover of your Casio Pathfinder, insert the four screws and tighten them with your optical-sized Philips screwdriver.

    How do I rest my Casio PAG-40 after I replaced the batteries?


    You need to shortcut AC point and battery. Take tweezers and touch AC and battery (+) simultaneously. Use an eyeglass to find AC point. It is marked on the movement with letters AC.

    How to get casio sea-pathfinder working after replacing batteries


    This certainly put me on the right track,but i found on my pathfinder mod 2271 that the four brass dots located down in the hole were unacessable with standard flat head tweezers so I inserted a small sewing needle and touched one of the brass dots while bridgeing the distance from the needle to the positive (+) surface of one of the four batteries with tweezer legs.
