Warnings, Cautions, and Safety Precautions Relating to Wall Mount Installation
Warnings, Cautions, and Safety Precautions Relating to Wall Mount
Installation
•
•
•
Make sure that you have read all applicable instructions before attempting to install the
wall mount.
Wall mounts that are intended to support monitors must be capable of supporting four
times the weight of the monitor when properly installed.
If wall mounts are to be installed on plaster board walls, we recommend that the mounts
be installed using steel or plywood plates sufficient to distribute the load over a large
section of the wall. Lead expansion bolts are neither adequate nor safe for this
purpose.
•
It is the responsibility of the hospital, institution, or its designated representatives to
determine that the wall is adequate to safely mount monitoring instrumentation. This
includes the selection of and proper installation of the appropriate fasteners and mounts.
In a new construction, or in a remodelled construction where the wall can be completely
or partially removed, a 16-gauge steel stud should be mounted for the purpose of
attaching the wall channel. This design safety factor is based on four times (4x) the
maximum rated load.
•
•
GCX Wall Channel: Always reposition the adjustable channel safety stop under the
adapter plate when the height of the monitor is changed.
The channel safety stop prevents the mounting device from inadvertently falling or
being pulled out of the wall channel. Do not remove this stop while the mount is
supporting a monitor.
•
•
•
Do not mount any portion of the monitor over a patient’s bed.
Do not exceed the maximum rated load specified for each wall mount.
Ensure that no electrical wiring, utilities, or piping interface with the selected wall
mounting location.
•
•
Do not install wall channel onto solid brick or brick veneer walls. Do not attempt to
install wall mounts onto crumbly wall material.
Check the mounting hardware holding the wall channel or bracket to the wall every 12
months. Tighten if necessary.

Battery Maintenance
This section provides some information on how to handle and maintain the battery.
Warning
Follow local governing ordinances and recycling plans regarding disposal or recycling
batteries and other device components.
About the
Battery
Storing the monitor for a long period of time without charging the battery can degrade the
battery capacity. A complete battery recharge (>90%) requires 8 hours in standby mode or 14
hours in operational mode. If the battery needs charging, connect the monitor to the AC outlet
as described “Charging the Battery”on page 3-9
If the monitor operates for less than one hour on battery power before the low battery alarm
operating times and conditions.
If the same symptom persists after the battery is conditioned and indicating a full charge, the

Battery Maintenance
Battery
Guidelines
To get the most out of the battery, observe the following guidelines:
•
•
The shelf-life of a fully charged battery is about 6 months.
After a battery has been activated, keep it charged. If it is not in use, recharge it every 3
to 4 months.
•
•
Condition the battery approximately every 200 deep discharges.
Remove the battery from the monitor if it is not being used regularly. (Leaving the
battery in a monitor that is not in regular use using the battery will shorten the life of
the battery).
•
•
Battery Disposal - We recommend replacing the monitor’s sealed, lead-acid battery at 2
year intervals. Follow local governing ordinances and recycling plans regarding
disposal or recycling of batteries and other device components.
Do not dispose of the battery in normal waste containers.
Warning
If the battery shows signs of damage or signs of leakage, replace it immediately. Do not
use a faulty battery in the monitor.
Checking
the Battery
Status
When the monitor is connected to the AC (mains) power supply, the battery charges
automatically.
Battery status is indicated several ways:
•
•
•
LEDs on the front panel of the monitor.
Battery gauge on the monitor’s main monitoring screen.
INOP messages
The AC LED is only on when the power cord is connected and the AC power is available to
the monitor. In this case, the battery can be either charging or fully charged.

If the battery operating time is less than 30 minutes, the battery icon flashes. A low
priority audio alarm sounds (1 beep every 4 seconds).
When the battery is empty, a "Low Battery" INOP message displays in the Message
frame and the audible alarm sounds. Pressing any front panel button clears the INOP
and silences the audible alarm. The battery icon continues to flash until the monitor is
powered down or automatically switches off.
If the new battery is partly or fully charged, the monitor starts operating.
Charging
the Battery
A complete battery recharge (>90%) requires 8 hours in standby mode or 14 hours in
operational mode.
To charge the battery:
Step
Action
1
2
3
Connect the monitor to the AC power source using the proper power cord.
Verify that the AC Input Indicator LED is lit.
Charge the battery for at least 8 hours. The battery may require a full discharge/
charge cycle to restore it to its normal capacity.

Battery Maintenance
Conditioning
a Battery
Battery conditioning re-calibrates the battery to ensure that it has accurate information on the
actual battery capacity.
Warning
Never use a monitor that is monitoring a patient to perform battery conditioning.
Why is Battery
Conditioning
Necessary?
The capacity of a battery decreases gradually over the lifetime of the battery. Each time a
battery is charged its capacity decreases slightly. Therefore, the operating time of a monitor
running off the battery also decreases with each charge cycle.
Battery conditioning ensures that the value storied in the battery for its fully capacity takes
account of this decrease, so that the remaining battery charge can be calculated accurately,
and the low battery warning given at the right time.
When Should
Battery
Conditioning
be Performed?
Battery conditioning should be performed:
•
Every 200 deep discharge cycles.
How to
Condition a
Battery
We recommend two full charge and discharge cycles to ensure proper conditioning,
independent of the initial condition of the battery.
If you need to continue battery powered monitoring, replace the battery in the monitor with a
different charged and conditioned battery. You cannot condition a battery in a monitor that is
being used.
Step
Action
1
Insert the battery that is to be conditioned into a monitor that is not currently
being used.
2

6
Disconnect the monitor from the AC power supply.
Turn on the monitor, and leave it on until it switches off automatically.
Turn the monitor Off using the On/Standby button located on the front panel.
Reconnect the monitor the AC power supply.
Charge the battery until it is full. (When you turn the monitor On, the 5 bars in
the battery gauge on the main monitoring screen will be illuminated).

As long as the NBP button is pressed,
the pump runs. If system pressure
reaches the hardware over-pressure

As long as the Volume button is pressed,
the safety valve and proportional valve
opens and remains at maximum.
As long as the Alarm Silence button is
pressed, the proportional valve opens
and bleeds off pressure at the rate of 3
1.5 mmHg/s. It is useful to control the
bleed rate to 3mmHg/s to facilitate
certain AAMI SP10 tests. Any time the
bleed rate falls below 3 mmHg/s, the
valve opens and remains at maximum as
long as the button is pressed.
Offset Adjustment
Momentarily press the Contrast Adjust
button invokes the Zero Calibration
routine that is performed immediately
prior to each blood pressure
measurement. This routine looks at the
pressure in the system, and if the
pressure is non-zero, an offset is applied
which causes the system pressure to
display as Zero.

Theory of Operation and System Architecture
Theory of Operation and System Architecture
This section contains a high level overview of the theory of operation of the major functional
modules of the monitor. Philips service providers perform Bench Repair at the assembly level.
For this purpose, they should review this high level information.
Please be aware that Philips only stocks assembly level parts.
System
Overview
The monitor is a full function monitor for use on adult and pediatric patients.
The functions performed by the system include monitoring patient ECG, heart rate,
1
respiration rate, blood pressure, blood oxygen saturation, carbon dioxide , and temperature.
In addition to monitoring and displaying the status of these physiological parameters, the
instrument performs various microprocessor-programmed analytical functions, such as:
•
•
Creating both visual and audible alarm signals when set limits are violated.
Creating and displaying warning messages when conditions are detected that would
degrade or prevent valid measurements.
•
•
•
Creating and displaying trend waveforms or tabular data.
Providing a synchronizing pulse for defibrillator operation.
Providing input to an optional recorder for printout of current or trend waveforms or
tabular data.
The monitor is essentially a battery-powered instrument. An internal charging unit is designed
to accept an external AC line voltage. The charger uses the external power source to maintain
a "float" voltage source available from the batteries.

The NBP section contains the pumps, valves, pressure measurement circuitry, and control
circuitry for the non-invasive blood pressure measurement. Pressure data is converted to
digital format and conveyed to the processor section.
Power
System
The power system section contains a power supply capable of operating the monitor and
charging the battery from an AC source of 100 to 240 VAC at 50 to 60 Hz. This section also
contains the circuitry. The battery provides the operating power for this power.
Micro-
The Microprocessor, Memory and Control section contains the system CPU and all digital
support circuitry. The latter includes the RAM, non-volatile memory, and real-time clock.
This section also contains the display logic, keypad (switch) interface logic, RS-232 I/O
control, defibrillator synchronization control, and printer logic.
processor,
Memory and
Control
Display
Keypad
The display is a TFT (color), backlit fluorescent LCD unit. The active screen size is 8.3 x 6.2
in (210.8 x 157.5 mm): 10.4 in (264.2 mm) diagonally, and the resolution is 640 x 480 pixels.
The keypad circuit contains five push-button membrane switches and two green LEDs. The
LEDs are driven by the power supply system and indicate the power source.
Signals from LEDs are returned to the microcomputer for processing and control as required.
The On/Standby button, connected directly to the power supply, toggles the power between
On and Standby modes. When in Standby, the display is blank, and no monitoring is
performed. However, the batteries are charging if an AC source is connected to the rear panel.
The Audio Alarm Control button is connected directly to the processor and to the system
power supply. Pressing this button turns off the battery fuse alarm in the system power
supply. Response of the processor depends upon the action in pressing this button. If
momentarily pressed (less than 2 seconds), alarms are paused temporarily for a preset interval
determined by the menu selection. If pressed twice within 10 seconds, the alarm sounding for
a specific parameter is silenced temporarily for a preset interval determined by the menu
selection. Other alarms, not related to this parameter, can still sound during this period. If
pressed and held for 2 seconds or more, the Audio Off condition is initiated.
The NBP button is connected to the processor. Response of the processor depends upon the
state of NBP operation at the time and the action in pressing this button. If momentarily
pressed, (less than 2 seconds), a single NBP measurement is obtained. If pressed for 2 seconds
or more, the processor initiates a STAT monitoring sequence. Pressing the NBP switch at any
time a pressure measurement is in effect causes the processor to terminate the measurement
and to deflate the cuff.

Theory of Operation and System Architecture
The Contrast button operates in conjunction with the navigation wheel to determine the
apparent contrast setting in the display. Changing the contrast is a change in the viewing
angle. Outputs of the button and wheel are connected to the processor.
Momentarily pressing the button sets the contrast to mid-range, factory-default value.
Momentarily pressing of the button, followed within 3 seconds by a rotation of the wheel are
processed to vary the contrast of the display. When there has been no wheel rotation for 3
seconds, the contrast control function is terminated by the processor. The contrast control
function is also terminated if the wheel is pressed any time within this 3 second interval.
Operation of the Volume button accomplishes similar functions for the volume of the heart
rate audible tone as the display contrast control button does for the display. Pressing this
button, enables the wheel to vary the tone volume.
Navigation
Wheel
This is a rotating, push-switch wheel. The associated wheel circuitry generates a pulse when
pressed and generates a digitally encoded pair of quadrature signals whose relative
magnitudes and polarities represent the angular position of the wheel. These outputs are
connected to the processor where they are interpreted as required for the functions involved.
Successive angular positions determine the direction of wheel rotation.
In addition to the functions performed when in conjunction with the keypad as described
above, the wheel operates in conjunction with the display to select menus and lists of
parameter variables.
RS-232 I/O
This is a rear panel 9-pin connector providing interfaces with other computer systems or
equipment. The driver for this "port" is a Universal Asynchronous Receive-Transmit (UART)
integrated circuit that interfaces this port with the microprocessor. The baud rate for this serial
transmission function is programmable from 1200 baud to 38.4 kilobaud.
Pin number 9 of the RS-232 connector is reserved for a Nurse Call signal. The nurse call
signal reacts when a low, medium, or high level alarm is activated.
Defib Sync
Pulse
The rear panel connector for the Defib Sync Pulse is keyed so that the connection of a cable
can be detected by the processor. When a connection is detected, the processor software
initiates the generation by hardware of a TTL-compatible pulse capable of driving 1 TTL load
over a three-meter cable with less than 200 pF capacitance.
The defib pulse is triggered by the detection of the R-wave in the QRS sequence of the ECG
wave-form complex. The pulse signal is active for 100 ±10 ms.
Speaker
The speaker is capable of providing 73 dBA of volume at a distance of one meter during
alarm conditions. The processor drives the speaker in different patterns as specified for the
different alarm priorities and conditions. Refer to the C3 Instructions for Use guide for
descriptions of alarm responses.

Theory of Operation and System Architecture
Recorder
The optional recorder module is installed in the right panel of the monitor. Refer to the C3
Instructions for Use guide for printing procedures. It provides users with the capability to
obtain hard-copy records of selected vital sign information.
Basic control of the recorder is implemented by two push-button controls on the recorder’s
front panel. The Continuous button is used to obtain continuous recordings of the real-time
waveforms displayed in the top two graphic frames. Along with the waveforms, the recorder
prints the values of the vital signs being displayed. The printing continues until the user
presses either recorder button a second time.
The Snapshot button initiates a snapshot printout for 20 seconds of the same information
recorded by the continuous control.
If scrolling is enabled in a display frame containing trend data when the Continuous button is
operated, then the trend record for that vital sign is printed. If the Snapshot button is
operated, then only the trend data on the display is printed.
The recorder may be programmed via the monitor menu display to print a snapshot recording
when an alarm condition occurs.
Printing is accomplished on 50 mm wide thermal paper at recorder speeds programmable up
to 55 mm/s.
ECG
Processing
The technique used in ECG senses the varying potential difference between two points at the
skin surface which respond to the electro-chemical actions of the muscular activity of the
heart.
Three electrodes are attached to the patient’s right arm (RA), left arm (LA) and left leg (LL).
The varying potentials at these locations are cable-connected to the ECG circuit inputs where
they are conditioned, and the difference of potential between two selected leads is digitized
before transmitting through opto-isolators to the processor. The processor-installed algorithms
operate on the signals to develop drivers for the graphic display and to compute the heart rate
in beats per minute (BPM).
In addition to the acquisition of the QRS waveform complex, the ECG input and subsequent
signal processing computing circuitry perform a number of other functions:
•
•
They detect a "lead-off" condition if one of the electrode connections is disrupted.
They detect the presence of pacemaker signals within the QRS waveform complex of
the ECG.
•
They generate a synchronization pulse for external use with defibrillators. The Defib
Sync Pulse output is available at a connector in the rear panel.
Respiration
Processing
The patient’s respiration is detected by using two of the three leads of the ECG electrodes and
cable. A low-level excitation signal is applied to these leads, and the variation of the thoracic
impedance caused by the breathing is sensed and processed for display and measurement.

Theory of Operation and System Architecture
NBP
Processing
The NBP processing uses an oscillometric technique to provide needed measurements at
selected intervals. This technique uses an inflatable sphygmomanometer cuff similar to those
used by clinicians in routine measurements.
A motorized pump inflates the cuff to approximately 180 mmHg initially, at which point the
pressure effectively stops the flow of blood. Then, under monitor control, the pressure in the
cuff is gradually reduced, while a pressure transducer detects the air pressure and transmits
the parameter signal to the NBP input circuitry.
As the pressure is reduced, blood flows in the previously occluded artery, and changes the
measurements made by the transducer. The point at which oscillation increases sharply is
defined as systolic pressure. As the cuff continues to deflate, oscillation amplitude increases
to a maximum, and then decreases. The peak oscillation amplitude is defined as the mean
arterial pressure. The point at which the system detects a rapid decrease in oscillation is
defined as the diastolic pressure.
SpO
Measurement of oxygen saturation in the blood uses a specrophotometry technique. It is based
on the facts that oxyhemoglobin and deoxyhemoglobin differ in their absorbtion of red and
infrared light, and that the volume of arterial blood in tissue changes during the pulse.
2
Processing
Using these facts, a pulse oximeter passes red and infrared light into an arteriolar bed and
measures changes in light absorption during the pulsatile cycle. The light sources are red and
infrared light emitting diodes (LEDs), while the detection is accomplished by a photo diode.
To identify the oxygen saturation of arterial hemoglobin, the monitor uses the pulsatile nature
of arterial flow. During systole, a new pulse of arterial blood enters the vacular bed, and both
blood volume and light absorption increase. During diastole, blood volume and light
absorption reach their lowest point. The measurement is based upon the difference between
maximum and minimum absorption, focusing on the pulsatile arterial blood.
In addition to the oximetry function, the input signals may be used to calculate heart rate.
CO
The Microstream CO board consists of an 80C552 Controller, the memory system (Flash

The gas inlet allows the connection of Microstream FilterLines. The FilterLines are detected
by the Optical Code Recognition.
Temperature
Processing
Measurement of patient temperature is accomplished by processing the signal from a probe
containing a resistor whose impedance is temperature dependent. The class of such
components is called thermistor.
The C3 is designed to accept the signals from electrically isolated Series 400 probes
manufactured by Yellow Springs Incorporated. Interchangeable probes in this series may be
used for esophageal, rectal, skin or surface, or airway temperature measurement. Probes are
furnished with a standard 10-feet lead. Extension leads are available.
The signal from the probe is conditioned by the monitor’s input circuitry, processed, and used
to drive the numeric display.
