How do you play the CD?
We borrowed this portable stereo from
a friend so we could play some music at our outdoor
wedding. We put a CD in the CD player and then pressed
the play button on the row of buttons
next to the CD player. It didn't work. Careful study
revealed that the row of buttons next to the CD player
controlled the tape player! And the row of buttons
that controlled the CD player? They are next to the
tape player!
Design suggestion
People generally expect the controls for a device to be on or close to the device. In this example, the CD buttons should be put next to the CD player and the tape buttons should be put next to the tape player. This is particularly important since the two sets of controls are quite similar.
