You are sitting in front of the TV, and want to turn down the sound. You grab the remote control, scan for the button with the down-arrow and push it. The TV gets louder! You pushed the up-arrow button instead of the down-arrow button. Why?
The letter "V" for volume is on the two volume control buttons. Although the buttons are shaped like up- and down-arrows for increasing and decreasing the volume, the letter "V" looks like a down-arrow. When you are scanning the remote control for a down-arrow, you see the "V" as a down-arrow, and press it. Unfortunately, the first "V" you see is on the up-arrow!
