ViewSonic Tablet PC V1250 35
4 Locate the memory expansion slot cover on the back of the Tablet PC shown
below. Remove the screw. Lift the memory door off the system.
Attention: Notice the notch on the extracted module. The notch’s
off-center placement allows the module to fit into the socket only
in one orientation. The replacement module will be similarly
notched to help you place it properly into its slot.
To install the new module, place it into the memory socket. The
module will only fit in one orientation. Insert the module at an
angle of approximately 30 degrees into the empty memory socket.
Then press it firmly so that the contact edge is driven fully into the
receiving socket.
Pivot the module until the latches on both sides of the socket snap
into place. (You will feel it solidly click into place.)
Replace the Memory Slot Cover and the Screw. You have now
completed the memory upgrade.
