Does the r1 have a Sleep Timer?
Yes, while listening to the radio or your iPod/iPhone, you can set the r1 to play for a set amount of time before it automatically shuts off using the Sleep Timer (in Setup mode). This allows you to set it when you go to bed, or lay down for a nap, and have the r1 turn off after you fall asleep. If you use the Sleep Timer while listening to an auxiliary device, the r1 will shut off after the programmed time period, but the auxiliary device will stay on.
