Kalbi23, to change the mains fuse in the T7, power off the unit and remove the power cord from the IEC inlet. Directly below the IEC inlet is a small rectangular insert that is part of the IEC module. You will then notice a small recess on the top outer edge of the insert. Take a small flat blade screwdriver and with the blade in the recess, gently pry forward. The fuse holder/fuse will pop free and you can then pull the fuse holder/fuse free of the IEC module to change the fuse.
Once you have changed the fuse, insert the fuse holder back in the IEC module ensuring that it is fully seated. Note that it can only be inserted one way so make note of it's direction when removing the holder.
