pressure on the transducer diaphragm that is higher than atmospheric zero, resulting
in an inaccurate zero reference value.
The ICP EXPRESS Monitor transducer zero reference value setting must only be
adjusted manually if the displayed value differs from the value recorded on the
Codman Microsensor connector housing or the patient's chart.
The mean ICP alarms will reset to default values (LOW ( ) : 0 mmHg; HIGH ( ): 20
mmHg) whenever the ICP EXPRESS Monitor power is turned OFF.
Do not autoclave the ICP EXPRESS Cable. Sterilize the ICP EXPRESS Cable using
Ethylene Oxide (EO) gas only.
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.
Always disconnect the ICP EXPRESS Monitor from its power supply before cleaning.
Do not sterilize the ICP EXPRESS Monitor.
Verify ICP EXPRESS 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 Monitor and external patient monitor pressure displays may be
inaccurate if used simultaneously with radiofrequency electrosurgical equipment.
The rear panel sensitivity selection switch must be set in the appropriate position
prior to connecting to the patient monitor. Do not adjust the sensitivity selection
switch while connected to a patient monitor, as inaccurate pressure readings can
result.
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 manual
zeroing or zero reference verification procedures.

Front Panel Controls (See Figure 1)
ON/OFF KEY—Turns the ICP EXPRESS Monitor operating system ON and
OFF. NOTE: When ON, the ICP EXPRESS Monitor can be powered either
from an AC power supply or from its internal battery. The ICP EXPRESS
Monitor will automatically switch to battery operation if no AC power is
available.

PATIENT Monitor ZERO KEY—Initiates an electronic 0 mmHg
reference signal for zeroing an externally connected patient monitor.
PATIENT Monitor 20 mmHg CALIBRATION KEY—Initiates an
electronic 20 mmHg reference signal for calibrating an externally
connected patient monitor.
PATIENT Monitor 100 mmHg CALIBRATION KEY—Initiates an
electronic 100 mmHg reference signal for calibrating an externally
connected patient monitor.
TRANSDUCER ZERO KEY—Zeroes the attached Codman
Microsensor transducer. The zero reference value of the transducer is
automatically stored in the non-volatile memory of the attached ICP
EXPRESS Cable.
MENU/ENTER KEY—Accesses the ICP EXPRESS Monitor MENU, or
ENTERS a selected display parameter value such as an alarm limit or a
zero reference value.
UP ARROW KEY—Moves the cursor on the MENU screen in the UP
direction, or INCREASES the value of a display parameter such as an
alarm limit or a zero reference value.
DOWN ARROW KEY—Moves the cursor on the MENU screen in the
DOWN direction, or DECREASES the value
of a display parameter such as an alarm limit or a zero reference
value.
ALARM SUSPEND KEY—Silences the audible portion of the mean
ICP alarm for a period of approximately two minutes.
AC Indicator
Lights whenever the ICP EXPRESS Monitor is connected to an AC
power supply.
BATTERY Indicator
Lights whenever the ICP EXPRESS Monitor is running only on its
own internal battery power.
BATTERY CHARGING Indicator
Lights whenever the ICP EXPRESS Monitor is connected
to an AC power supply and the internal battery charger is operating.
The Battery Charging indicator will remain lit even when the battery
is fully charged.
Display Backlight ON/OFF Switch
Used to turn the front panel liquid crystal display backlight ON and
OFF. When operating the ICP EXPRESS Monitor on battery, the display
backlight can be turned off to conserve power.
Patient Monitor Sensitivity Selection Switch
Used to set the sensitivity of the ICP EXPRESS Monitor external patient
monitor output signal to either 5 μV/V/mmHg or 40 μV/V/mmHg. This
switch is preset to 5 μV/V/mmHg at the time of manufacture. Refer to
the patient monitor manufacturer's instructions to verify the pressure
channel sensitivity requirements of a specific patient monitor.
Patient Monitor Interface Connector
Compatible patient monitors can be connected to this
receptacle using the appropriate Codman Patient Monitor Interface
Cable. CAUTION: Codman Patient Monitor Interface Cables must
be used only with patient monitors for which they are specifically
designed and designated
