How do I short circuit new battery, as directions say?

Sometimes watch movements need to be reset after a battery change. This is not always the case, so if your watch is working OK you do not need to reset. If the watch is not operating properly then you will need to short-circuit two points inside the watch to reset it - this is usually done with something like a pair of fine point tweezers. With the back of the watch removed, look for contacts on the circuit board - usually marked as '+' and '-'. Use the points of the tweezers to briefly make a connection between the contacts. That should do it, but sometimes it needs to be repeated.
If you have no success with this, it might be easier to take it to anywhere that does battery replacements and let them sort it out.

If you take a jeweler's lupe near where the arrow is you will see the word "reset" in the plastic.
There is a deep hole in the plastic with contacts below. That is the reset, and that is why you must use very sharp pointed tweezers to make contact with the back of the battery.

I think if you do not have sharp tweezers, you can probably put a sewing pin down the hole, and then connect with a small screwdriver to the back of the battery..

You actually do not need to do that. Your watch should be up and running after you change the battery. Short-circuiting the watch is for restoring it to factory settings and it should be done by a watch professional. Doing a wrong short circuit will can damage your watch permanently.
Thank you for using FixYa. Have a great day.

Take a pair of tweezers and put one leg on the battery case and the other leg on the adjacent watch case.

It sounds like a short circuit somewhere in the watch. A visit to the authorised dealer sound necessary.

To find your nearest dealer go to "casio.com" click on "support" , then from the menu on the left, click on "repair and service" to find your dealer or service center.

When you change the battery on this watch you have to short the circuit board. You need a fine pair of tweezers and you need to look on the circuit board for an arrow or bare spot, put 1 end of the tweezers on that place on the circuit board and the other on the battery at the same time. that should do the trick if the battery was installed correctly and the battery is good.

You will find them on the module itself.
So after replacing the battery look on the PCB (printed circuit board) for the letters"AC" and "VSS". Adjacent to these markings there should be little contact points (probably gold or silver looking in colour)
Use a paper clip or similar and bridge (short) these two points simultaneously. Please rate my solution.

The reset trick works with other Casio Alarm Chrono digital watches, such as my old Model W-720, as well. After the new lithium coil cell is installed and secured with the spring clip, the watch may show random segments in the LCD display or may simply be blank. Insert a sewing needle, paper clip, or blade of a small jeweler's screwdriver into the hole on the back of the movement stamped "AC" (All Clear) to momentarily connect the gold plated contact at the bottom of the hole to the stainless steel battery clip. The battery clip in most such Casio watches is connected to the "+" terminal of the coin cell. This will reset the CMOS chip and it should start up with the watch displaying 12:00 and the date at 1-1. Then, use the control buttons to set the time and date in the normal fashion.
