3.12 FERRITE BEAD INSTALLATION

WARNING: If you are using your 650 in a European Community (CE) country or in Australia or New
Zealand, you must attach a ferrite bead to the 655174 PC Interface Cable and the 6116 Charger Adapter Cable
in order to comply with the Residential, Commercial and Light Industrial Class B Limits for radio-frequency
emissions specified in EN55011 (CISPR11) for Industrial, Scientific and Medical laboratory equipment.
These ferrite assemblies are supplied as part of cable kits.
To install the beads, follow these steps:
 Make a small loop (approximately 5 cm in diameter) in the cable near the 650 MS-8 connector.
 Lay the open ferrite bead assembly under the loop with the cable cross-over position within the cylinder
of the ferrite bead. See the drawing below for assistance.
Snap the two pieces of the bead together making certain that the tabs lock securely.

When the installation is complete, the 655174 and 6116 cables should resemble the following schematic
drawings.
