Proteus-IV label information The Proteus-IV label has the size of 6x6mm. It contains the device name “Proteus-IV”, parts of its article number “2101102400” and the serial number of the entity. The 2101102 is the HVIN. The label is placed on the shielding of the radio module. The font size used, is 2.5pt and thus smaller than 4pt (~1.27mm). The FCCID, ISED and HVIN number do not fit to the label due to the small size. It is part of the user manual and part of the label of the packaging.
