Crit-Line; Crit-Line Graph; Other Options; Options Which Require A “Key” For Activation - Fresenius Medical Care 2008T Operator's Manual

Appendix C

Crit-Line

The Crit-Line option must be set to 'Yes' in Service Mode in order to use the Crit-Line in a
Clip (CLiC) device during a hemodialysis treatment. Note that the BTM and BVM module
options are unavailable if Crit-Line is selected.

Crit-Line Graph

The operator can choose to display either the BV (Blood Volume) or Hct (Hematocrit) graphs
on the "Crit-Line" screen. The default Crit-Line graph is the BV graph.

Other Options

There are other options on these screens that may not be specifically described here.
Generally, these are setup options that are based upon the presence or absence of other
modules or hardware.
Options which require a "key" for activation
Certain options are extra cost or limited in availability and must be activated by use of a
special code stored on the functional board. Examples of this sort of feature include OLC.
Upon purchase of such a feature, use the following procedure to activate it on the machine.
Caution: This procedure should be performed by a qualified individual. Be sure to follow
electrostatic discharge (ESD) procedures when removing the board and replacing the
EEPROM chips on the board.

To transfer the option, the EEPROM "hardware key" is placed in IC20 on the functional
board in place of the calibration EEPROM. Save the calibration EEPROM as it must be
returned to the same machine. Be sure to match the notch on the EEPROM with the
socket.

Return the functional board to the machine and turn on the power.

Upon power up the functional board reads the contents of the memory from the
EEPROM key.

The message "New feature loaded. Power off. Replace eeprom." is displayed.

Turn off power, replace the EEPROM "hardware key" with the calibration EEPROM,
and turn the power back on.
Note: The key may be used only once. If the key is reused, the machine locks up and
displays the message "Eeprom already used. Power off. Replace eeprom".
