Safety Considerations (Prism & Prism SE)
Read the following sections before using the Prism or Prism SE monitors. These cautions and
warnings are presented to both increase patient safety and prevent damage to the monitor.
WARNING: Shock hazard. Do not remove cover. There are NO user
serviceable parts. Contact qualified service personnel for all service
and repair.
Do not under any circumstances remove grounding conductor from
power plug. If there is any doubt about the integrity of the protective
earth conductor arrangement, operate monitor on internal battery
power until AC power supply protective conductor is fully functional.
To maintain patient electrical isolation, connect only to other
equipment with electronically isolated circuits.
WARNING: As with all electrical equipment, carefully route patient
cabling to reduce possibility of patient entanglement or strangulation.
WARNING: There is a potential fire hazard when used with oxygen-
emitting equipment, and danger of explosion when used near
flammable anesthetics.
WARNING: Do not use monitor during magnetic resonance imaging
(MRI). Induced current could potentially cause burns. The monitor
may affect MRI image and the MRI unit may affect the accuracy of the
monitor.
WARNING: To avoid shock hazard with RS-232 System
Interconnection, first consult IEC60601-1 for system interconnection
guidance. Specific requirements for system interconnection are
dependent upon device connected to the monitor and relative locations
of each device from patient, and relative location of connected device
to room containing the monitor. In all circumstances, the monitor
must be connected to a grounded AC power supply. The monitor is
referred to as an IEC 601/F device in the Summary of Situations
contained in IEC60601-1.
WARNING: When a remote display monitor is connected to the unit
via the VGA connector on side of unit, it is essential the remote
monitor is powered from a properly rated and approved isolation
transformer. This is required to meet earth leakage limits of 0.5 mA,
as per IEC60601-1, Cl. 19.3 for monitor.
WARNING: When connecting monitor to any other instrument, verify
proper operation before clinical use. Refer to the other instrument’s
operation manual for complete instructions.
WARNING: All input/output interfaces to the patient monitors must
be CSA601.1/UL2601-1, EN 60601-1 approved devices.
WARNING: Do not under any circumstance use replacement parts
and connect devices that are not approved by Medical Data
Electronics.

iv
CAUTION: Always locate the Prism or Prism SE and its power cord
away from any electrosurgery and diathermy equipment and its power
cord and cables.
CAUTION: When operating either the Prism or Prism SE monitor
from an AC power source, the wall receptacle must be a three-wire,
grounded, hospital grade outlet. Use only the monitor’s original
hospital grade AC power plug and cord, or an equivalent hospital
grade plug and cord. If in doubt about integrity of grounding of the
main supply connection, the unit must be operated by battery power.
CAUTION: DO NOT plug the unit into a multiple outlet power strip
to avoid summation of leakage currents.
CAUTION: Do not use in ambient temperatures above 40° C or below
5° C.
CAUTION: When using an external DC power source, the
equipotential connector must be used as a protective ground terminal.
Symbols (Prism & Prism SE)
The following symbols appear on the Prism and Prism SE monitors, and may appear on accessory
items. Familiarize yourself with these symbols and their meaning before using the monitor.
Type CF Defibrillation Protected Equipment: Isolated patient connections
comply with allowable leakage current limits for direct cardiac application
and are protected against effects of defibrillation.
Type CF Applied Part: Isolated Patient connections comply with the
allowable leakage current limits for direct cardiac application.
Attention: Consult accompanying documents.
Replace Fuses as Marked: For protection against fire, replace only with
fuses of same type and rating.
Caution: Dangerous voltage.
Alternating Current: 100-240V @ 50/60 Hz.
Equipotential Connection: When external DC power is used, the
equipotential connection must be used as a protective ground terminal.
Fuse: Voltage and current ratings appear adjacent to symbol.
The CE symbol indicates device conforms to the Medical Device Directive.
Single patient use only.

Fixed Function Keys (USA and International)
The Prism & Prism SE monitor includes the following nine (9) fixed functions keys: ON/STBY,
ALARM SUSPEND, ALARM SETUP, FREEZE, NIBP START/STOP, PATIENT TYPE,
SYSTEM SETUP, PAGE HOME, and RECORD. Each of these keys, as the name implies (or
symbol for International), is fixed and performs its intended function regardless of the monitoring
scenario. A brief description of each is provided below.
ON/STBY
Turns the display on and initializes the monitor when ON is pressed. When the monitor is turned
on,you will hear two beeps. The monitor is returned to standby status by pressing STBY. When
in STBY, the batteries continue to be charged if the monitor is connected to AC power, but no
monitoring or storing of data occurs. The Prism SE batteries will also charge when using eternal
DC power.
ALARM SUSPEND
Temporarily suspends alarm tones. The factory defaults for alarm suspend intervals are 180
seconds in adult mode, 90 seconds in pediatric mode, and 60 seconds in neonatal mode. If an
alarm limit is violated, pressing ALARM SUSPEND will silence the alarm tone. Pressing the
key again before the suspend time period has elapsed will reactivate the audible alarm tones if the
alarm condition still exists. While alarms are suspended, the following message will appear on the
monitor screen:
ALARMS SUSPENDED XXX
The XXX will be replaced with the number of seconds remaining until the alarm suspend
condition is removed.

1-3
ALARM SETUP
Displays the alarm status for all vital sign parameters. Alarm ON/OFF status, alarm priority
level, high and low limits, and recording type for each active parameter are displayed.
A bell… … next to the listed parameter indicates that one or more alarms for that parameter
is ON. An Xis displayed when all alarms for the associated parameter are OFF.
FREEZE
Freezes all displayed waveforms for evaluation purposes. Pressing FREEZE again releases
waveforms.
NOTE: Waveforms cannot be frozen during recording. Initiating a
recording will also release the frozen waveforms.
NIBP START/STOP
Pressing the NIBP START/STOP key immediately initiates an inflation and measurement. You
can also press the NIBP softkey to access the setup keys for setting automatic measurement
intervals.
PATIENT TYPE
The PATIENT TYPE key is used to select or display the current patient type. The selections are
ADULT, PED, and NEO.
SYSTEM SETUP
SYSTEM SETUP is used to change the monitoring conditions that your monitor is currently set
up for.
PAGE HOME
Returns the monitor display to the HOME PAGE screen (i.e., the screen normally displayed
during patient monitoring).

1-4
RECORD
Initiates a 16-second recording of any one or two parameter waveforms. To stop a recording in
process, press RECORD prior to completion of a manual or alarm recording. To specify the
parameters to be recorded, press the softkey(s) of the desired parameter(s) within two seconds
after pressing the RECORD key. If no parameters are selected after pressing record, a 16-second
strip of ECG waveform will be recorded.
NOTE: Active waveforms (i.e., parameters currently being monitored)
do not need to be displayed in order to acquire a recorded waveform.
Parameter Softkeys
The monitor is equipped with eleven (11) softkeys. Softkey operation changes depending upon
the monitoring mode, parameter, or configuration options being accessed. Four parameter
softkeys are located to the right of the display screen. Seven parameter/system softkeys are
located below the display screen.
WAVEFORM SOFTKEYS
These four softkeys, located on the right side of the front panel, provide access to the function
keys of the parameters displayed in the waveform display zone. ECG is always assigned to the
top waveform trace, and as many as three additional parameters, when available (i.e., installed),
can be assigned to trace 2, 3, 4, or 5 depending upon options.
SYSTEM SOFTKEYS
The function of these seven softkeys, located directly below the display screen, depends on the
label or function key displayed directly above the softkey. In the HOME PAGE state, parameter
labels and associated numeric values may be displayed directly above one or more of the
softkeys. To access the function keys for any of these parameters, press the softkey under the
parameter label and a page of function keys that relates specifically to that parameter will be
displayed.

1-5
Indicators
The monitor includes up to four indicators, which illuminate to notify the operator of a specific
activity or situation. These indicators notify the operator of AC power, battery charging, and
alarm status.
AC ON INDICATOR
The green AC ON LED (Light Emitting Diode) illuminates when the monitor is connected to AC
power.
BATTERY CHARGING INDICATOR
The yellow CHARGING LED illuminates when the monitor’s batteries are charging. The
CHARGING LED will not be illuminated when the batteries are fully charged, or when the
monitor is not connected to AC power.
ALARM INDICATORS
When flashing, one or more parameters are alarming.
When lit, one or more alarms are suspended, OR all alarms are turned off.
