IMPORTANT: Tableau strongly recommends that the T35i be on a
dedicated power supply lead. Switching the T35i on/off can lead to
large current/voltage surges which can interrupt the operation of
other devices which share a power supply connection with the T35i.

In most situations, Windows XP handles READ-ONLY
bridges correctly and will work optimally when leaving
switches 2 and 3 in the OFF (default) state.
However, Tableau has seen cases where Windows XP will
not allow a user to access a READ-ONLY partition. If you
encounter a situation in which Windows XP reports that a
volume is "write protected" and will not allow you to
access the partition, then try the switch setting
recommended for Windows 2000, below.
