The ICP EXPRESS Monitor will erase the previously stored zero reference value and
store a new zero reference value in the ICP EXPRESS Cable whenever a new Codman
Microsensor is zeroed, or when the user chooses to adjust the zero reference
manually. The memory element in the cable is designed to perform over one million
erase/write cycles and will retain data for several years. NOTE: A transducer zero
reference value of "–99," as displayed by the ICP EXPRESS Monitor during a manual
zeroing or zero reference verification procedure, is an indication of an ICP EXPRESS
Monitor EEPROM read failure. This may be a result of a simple random timing error by
the ICP EXPRESS Monitor and can be corrected by selecting the ADJUST REFERENCE
menu item and manually adjusting the displayed zero reference value to the correct
zero reference value. However, this error can also be an indication of a failure in the
ICP EXPRESS Cable EEPROM circuit due to deterioration associated with age or
mechanical abuse. CAUTION: Discontinue use of any ICP EXPRESS Cable that
continues to yield a "–99" transducer zero reference value (as displayed on the ICP
EXPRESS Monitor screen) during the manual zeroing or zero reference verification
procedures
CAUTION: DO NOT immerse the ICP EXPRESS Cable in any liquid, or allow liquid to
enter the plug or connectors Do not use cable if connectors become wet Erratic
results can occur
CAUTION: Verify cable integrity prior to use Do not use any cable that fails to meet
the pin-to-pin resistance or electrical leakage specifications
The ICP EXPRESS Cable integrity must be evaluated by qualified technical personnel.
The cable must be routinely inspected for pin-to-pin resistance and electrical leakage.
Pin-to-pin resistance can be measured using an ohmmeter. Resistances between pins
1–1, 2–2, 3–3, and 4–4 must be one ohm or less. See Figure 8.
Electrical leakage can be evaluated using an ohmmeter. Measure the open circuit
resistance between pins 1, 2, 3, 4 (inclusive) and all other pins accessible on the ICP
EXPRESS Monitor connector end. The open circuit resistances must be 300 MΩ or
greater.

Safety
The ICP EXPRESS Monitor is Class I, CF Type Medical Equipment.
The ICP EXPRESS Monitor is protected against defibrillator discharge with no
interruption to normal functionality.
The ICP EXPRESS Monitor meets or exceeds the requirements of the following
standards:
IEC 60601-1 Medical Equipment (2005), Part 1: General Requirement for Safety
IEC 60601-1-2, 2nd Edition, 2001, The Electromagnetic Compatibility Requirements
for Medical Electrical Equipment
NOTE: When connecting the ICP EXPRESS Monitor to an external patient monitor,
compliance with EN55011 is achieved only when using an approved Patient Monitor
Interface Cable which has an EMI Suppression Core attached adjacent to the 9-pin
