Upgrading a memory module 3. Maintenance 58 Your machine has a dual in-line memory module (DIMM). Use this memory module slot to install additional memory. Order information is provided for additional memory module. (See "Available accessories" on page 52.) 4 Holding the memory module by the edges, align the memory module on the slot at about a 30-degree tilt. Make sure that the notches of the module and the grooves on the slot fit each other. 1 Installing a memory module 1 Turn the machine off and unplug all cables from the machine. 2 Grasp the control board cover and remove it. The notches and grooves illustrated above may not match those on an actual memory module and its slot. 5 Press the memory module into the slot with care until you hear a 'click'. 3 Remove the new memory module from its bag. Do not press the memory module strongly or the module may be damaged. If the module does not seem to fit into the slot properly, carefully try the previous procedure again.
