FAQ and troubleshooting
The Rio is connected to the USB, why doesn’t the computer recog-
nize it?
First, make sure the Rio software is running and check to make sure the USB cable is fully
connected to both the Rio and to the computer. Then, turn the Rio off and back on.
Is the Random menu function truly random?
No. The Random function uses an algorithm called pseudo-random which is common to all
computers. The Rio selects a seed number and then enters a list of predetermined random
numbers to play music in a seemingly random order. If the same seed is picked, the Rio may
play songs in the same order.
What does the Rio Hold feature do?
The Hold feature on the Rio locks all buttons and controls except the Power switch. This is
useful at times when the Rio may be bumped or jostled. For example, when exercising.
