Standby/On Switches the unit between a low power standby mode (indicated by dim power LED) and on (indicated by bright power LED). Standby is a low power mode where the power consumption is less than 3 Watts. The unit may be left in standby mode when not in use. 2. Infrared sensor Receive IR commands from the supplied remote control. A clear unobstructed line of sight between the remote control and the sensor is required. 3. Phones Allows for the connection of stereo headphones with a 3.5mm jack plug. Headphones with an impedance of between 32 and 600 ohms are recommended. Note: Plugging in headphones will automatically mute the loudspeaker output. 4. Source Press to cycle through the available input sources such as tuner, MP3, CD, DVD and aux inputs. 5.

Note: Plugging a source into the front panel MP3 input overrides the DD30 docking station (which is also selected by selecting the MP3 source via the remote control or front panel Source button). Simply remove the jack from the front panel socket to automatically re-enable the DD30 docking station as the MP3 source. There is no need to unplug the DD30 docking station whilst using the front panel MP3 input and it will continue to charge a docked iPod as usual. 11.
