User Guide
Maintain the outgoing airflow to dissipate internal heat.
Note: Do not block the ventilation slots. Otherwise, the computer
may overheat.
Connect to headphones or headsets with a 3.5 mm (0.14 inch), 4-pole
plug.
Note: This jack does not support standalone external microphones. If
you use headsets, choose one with a single plug.
Insert an SD card or a MultiMediaCard (MMC) into the slot for data
transfer or storage.
