This document is the CASIO FX-9860G Slim Hardware User's Guide, which provides instructions and guidelines for using the product, as well as information on compliance with FCC regulations.
The Casio fx-9860G Slim is a graphing calculator that requires initial setup before first use. Users must install batteries and adjust the display contrast by accessing the SYSTEM menu. The device connects to compatible PCs via USB using the bundled Program-Link software (FA-124).
You must load batteries and adjust the display contrast because they are not loaded at the factory.
The batteries must be replaced once every one year to prevent leakage and damage.
Do not use an oxyride battery or any other type of nickel-based primary battery.
