the main menu. Press the left button to
scroll to Sleep. Select with the right
button.
2. The Sleep menu offers four pre-pro-
grammed times: 5, 30, 60 and 90
minutes. Press the left button to scroll
through the times, and press the right
button to make your selection.
3. Press and hold the right button to
save your time selection and exit this
mode.
