Notify qualified service personnel for repair or replacement.
IR150B Staff and IR155B Patient Stations

for repair or replacement.
PK800A Secondary Power Supply
The only user serviceable part is a 4A, 125 VAC fuse (1.25"×0.25").
• Disconnect power to the associated SS100 transformer. If the SS100 is hard wired,
locate the associated breaker and turn it off. If a means cannot be established to
remove power to the SS100, then contact qualified service personnel and do not
proceed further. The SS106 powering the associated PK151A or PK152 should
also be powered down in the same fashion.
• Once power has been disconnected, firmly grasp the black fuse holder knob on
the side of the PK800A, push in and rotate it counterclockwise. Pull out on the
knob and the fuse will be exposed.
• Remove the fuse and insert the new fuse. Reinsert fuse holder knob. Restore
power to the system.
For repair or replacement of any other parts, contact qualified service personnel. A list
of replacement parts and numbers appears in the
Replacement Parts
section.
