How do I operate the HYF013 Series fan?

Place the fan on a level and dry surface and plug it into a polarized 120 Volt AC wall outlet. Turn the knob to select the appropriate fan speed: High, Medium, or Low. Press the oscillation button to activate or disengage oscillation. You can operate the automatic shut-off timer by turning the timer knob to the desired setting between 10 to 120 minutes, and turn the knob counterclockwise to the ON position to turn the fan back on after shut-off.
