627B LeaseMaker Features


  • Documentation Fee field added. The doc fee can be taxed and capitalized or paid at drive-off. The tax on the doc fee can be capitalized or paid at drive-off.

  • Fuel Cost Comparison Routine. This new routine computes the fuel cost for two vehicles and compares them. The annual fuel costs are computed, the annual and monthly savings, annual fuel consumption, and percentage savings. Uses both the U.S. miles-per-gallon and metric liters/100km systems.

  • 0% Loans. Both retail and balloon loans can be calculated with a 0% interest rate, even with credit insurance.  For retail loans, the last payment is adjusted, if necessary, to make the finance charge exactly $0.00.  On balloon loans, the balloon payment is adjusted.  See 0% Loans Frequently Asked Questions.

  • Interest buy-down amounts can be calculated for 0% loans with the enhanced dealer-reserve routine. 

  • See Instant Upgrade and Returning Your Calculator for Service.

  • Rebates used as cash downpayments can be excluded from Sales Tax, and the downpayment tax, if any, can be capitalized for Sign-&-Drive deals.
    See Instant Upgrade and Returning Your Calculator for Service.

627B Battery Replacement

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).

You will have to setup the calculator after replacing the batteries.  See Setup Codes or 627B User's Guide.
