SAFETY AND EMC CONSIDERATIONS
650 MDS
Before using the 650 MDS, the user should carefully read the caution messages listed below and
should review Section 13 of this manual on Safety Considerations.
CAUTION: The YSI 660 can be used with an optional 6117 rechargeable battery pack that
contains Nickel Metal Hydride Batteries which if misused or not disposed of properly can cause
injury. In addition, the rechargeable battery pack can be charged with a cigarette lighter adapter
that could have safety concerns if not maintained properly. The user MUST read the safety
information concerning the general use of these batteries and their charging which are found in
Section 13 of this manual prior to using the battery pack.
CAUTION: When using the YSI 650 MDS, please be aware that electromagnetic compatibility
(EMC) performance issues may occur under certain conditions, such as when the sonde is exposed to
certain radio frequency fields, fast transients, or electrostatic discharge. If you are concerned with
these issues, consult the Declaration of Conformity that was enclosed with your instrument. Specific
conditions where temporary sensor problems may occur are listed in this document. If you are
unable to locate the Declaration of Conformity that was shipped with your instrument, contact your
local YSI representative, or YSI Customer Service in Yellow Springs, Ohio for a copy of the
document. See Section 14, Warranty and Service Information for contact information. In addition, if
you are using your 650 in a European Community (CE) country, Australia, or New Zealand you MUST
install a clamp-on ferrite bead on your PC interface cable and rechargeable battery pack 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. See Section 12 for information on installing the ferrite bead assemblies.
TROUBLESHOOTING
The 650 MDS is characterized by sophisticated software that should provided trouble-free operation.
However as with all high-capability software packages, it is always possible that the user will
encounter circumstances in which the instrument does not respond to keypad entry. If this occurs,
the instrument function can easily be restored by removing and then reapplying battery power.
Simply remove either your C-cells or rechargeable battery pack from the battery compartment, wait
30 seconds and then replace the batteries. See Section 2.5 below for battery removal/reinstallation
instructions. See Section 11 below for other troubleshooting information.
