Shock Danger! Be sure to unplug the PS-B unit from its power supply prior to installing the
HDD unit.
• Since the HDD unit is a precision instrument that has a low resistance to shocks,
be sure it is neither hit by nor pressed strongly against another object when
installing it.
• Even when the PS-B unit’s screen display disappears, the power might be
distributed inside (such as the “Standby” status etc.). Be sure to confirm that the
power supply switch on the top side of the PS-B unit is OFF or that the power is
not supplied to the PS-B unit.
• The HDD unit can not be attached to the PS3001-BD.
(Only for PS3000-BA.)
