I have Casio 991-MS calculator and have an issue to change my display brightness,when I switching with Mode key,I can’t find Cont mode,while in another same calculator there is , anybody can help me with that quickly?
Hi, Here’s an image taken from the Additional functions User guide 2 for the calculator, that may help. It doesn’t specify exactly what setup options are available if you press the Mode button >3 times but it says that it actually changes the calculator setup so perhaps the brightness function is in there. Worth a look perhaps.
