10.3 Replacing fuses
When servicing the unit, always first switch the unit
off by removing the plug from the wall outlet and then
wait for 2 minutes before touching any electrical
parts.
Note that the mains voltage is always present at the
mains terminal under the main control PCB cover,
even if the unit is switched off from its own mains
switch.
The fuses are located on the base of the chair below the
on/off switch. Turn the fuse holder counter-clockwise to
remove it from the chair. Replace the old fuse with a new
one of the same type and rating. Put back the fuse holder
and switch the chair on.
