Shock Danger! Be sure to unplug the PS-A unit from its power supply prior to installing the
HDD unit.
• Since the HDD unit and the PS-A unit’s circuit board are precision instruments that
have a low resistance to shocks, be sure they are neither hit by nor pressed strongly
against another object when installing the HDD.
• Even when the screen display of the monitor connected to the PS-A unit is blank, the
power might be distributed internally (for example, in the Standby state). Make sure
that the power supply of the PS-A unit is off when installing or removing the HDD unit.
