Change to the 45 Degree Cartridge: All Current CMC Models

The 45 Degree black metal cartridge is labeled 45° on the end.

Older models may have black plastic cartridge.

Your cartridge may look slightly different than displayed below depending upon what CMC model you have, but changing the cartridge uses the same process.

Push blade cartridge release down to eject the current blade cartridge.

Turn the new cartridge over and reinsert into the head with the blade facing the CMC board and the notch on the back of the cartridge facing the head, until it clicks into place.

It can only be inserted one way.
