Why is my calculator screen so dim.?

Question

thank u very much

Answer 1

Find the 2nd key and the up and down cursor keys. Notice that between the up and down cursor keys there is a symbol indicating contrast adjustment.

Now, to give the screen more contrast, first push the 2nd key. Notice that the cursor is now a blinking rectangle with an up arrow inside, indicating that the 2nd function is engaged. Press the up cursor key once for a one-step increase in contrast, or hold it down for a continuous increase in contrast (stop pressing when the contrast is satisfactory).

To reduce the contrast, perform a similar operation by pressing the 2nd key and then pressing the down cursor key.
