To change batteries, you should first have the replacement batteries at hand (two CR2032 Lithium batteries are required) and a small screwdriver to remove the two screws on the back of the calculator.

Make sure you install the new batteries with the same orientation (plus and minus) as the original batteries (this is also shown on a diagram on the inside of the back cover). 

The CR2032 battery is available at Radio Shack stores, camera stores or departments, and other places that sell small batteries.  It is round, about 0.75 inches (19 mm) in diameter and 0.125 inches (3.175 mm) thick.

Click here for detailed instructions on changing the handheld calculator batteries (instructions are also in the User's Guide).

If you need assistance in changing the batteries, contact our office at 1 800 843-7766 between 9 AM and 5 PM Eastern Time, Monday through Friday.

You may have to setup the calculator after replacing the batteries.  See Setup Codes or 623H User's Guide.

If the calculator still does not work, the calculator and/or card are probably defective and need repair.  The calculator and card should be Returned for Service.

This is a list of the most recent changes together with the date they were made and the software Series number.  The most recent version is at the top of the following list.

There are many versions of this program in use.  Some are quite old, and although they may appear to work properly, they may not be Year 2000 Compliant.

If you are using a version earlier than Series  L99, it should be upgraded.  If you have an earlier style calculator, you need to send it to us -- we will allow a trade-in allowance towards a new 623H.  (Earlier style calculators cannot run the current programs because they are too long and complex.)

If your calculator requires an update and is working properly,
you can order an Instant Upgrade without sending in your calculator.

If your calculator is not working properly and needs repair, or you wish us to install the new software, clean and check the calculator, and replace the calculator's batteries (or if you have an earlier-style calculator that you wish to trade in) see Returning Your Calculator For Service.

Configuration of the calculator is done through the Setup Routine.  After you press the Setup Function Key, you have to enter a code number to access a routine.

This is a list of the setup codes and a short description of what they do.

Full details are in the 623H User's Guide.
