SP25M disc styli carrying capability

SP25M is compatible with disc styli when using the SM25-1, SM25-2, SM25-3 or SM25-4 scanning modules and their respective standard stylus holders.

For SM25-1 and SM25-2, it is mandatory that a 20 mm long extension must be used between the respective stylus holder and disc stylus unless the disc has an effective working length of 20 mm or more.
