Special Notice to User
Malfunction caused by EMC
The Cardimax FX-7102 complies with the safety standards IEC60601-2-25 (1999) and
IEC60601-1-2 (2001). However, if there is a strong electromagnetic wave nearby that
exceeds the prescribed limit, the device could malfunction. If this happens, provide
the required countermeasures.
Influence of radiation electromagnetic wave:
The use of a cellular phone could affect the operation of the FX-7102. Alert persons in
a facility where medical electronic equipment is installed to turn off their cellular phones
and small radio equipment.
Influence of bursts and conduction electromagnetic wave:
High-frequency noise from other equipment may infiltrate into the FX-7102 through the
AC outlet. Identify the noise source and stop use of the relevant equipment if possible.
If this equipment cannot be shut down, provide the countermeasures for this noise
route using a noise suppressing device, etc.
Influence of static electricity:
The discharge of static electricity could affect the operation of the FX-7102 in a dry
environment (room), particularly in winter. Before using the FX-7102, humidify the
room or discharge static electricity from a patient and person who will record the ECG.
Influence of surge (lightening):
If there is a thunderstorm occurring nearby, it might cause a voltage surge in the FX-
7102. If you expect any danger, unplug the power supply cord from the AC outlet and
run the FX-7102 on built-in battery power (optional). Also use an uninterruptible power
supply, if you have one.

iv

Safety Precautions
• Before using the Cardimax FX-7102, be sure to read this section to ensure safety and
correct operation.
• Be sure to follow the precautions given below. These are important matters related to
safety.
Safety notifications
The following three safety notices alert the user to the level of hazard and damage that
may result from not following the instructions or from misuse of the equipment.
Safety icons
The following icons appear with the instructions given in safety notices. They basically
categorize what you should do or not do in the following manner:
DANGER
WARNING
CAUTION
Ignoring these instructions could cause death, serious
injury, or major fire.
Ignoring these instructions could cause death, serious
injury, or fire.
Ignoring these instructions could cause injury or damage

CAUTION
DANGER
Precautions on measurement program
The equipment may measure the ECG waveform incorrectly due to external noise
(such as a drift of baseline, electromyogram, AC interference, etc.). Another matter
which requires careful consideration is that tiny R waves in V1 and V2 may be
overlooked and the S wave could be interpreted as Q wave.
Precautions on AC adapter
• Be sure to use specified AC adaptor (OA-467).
• Be sure to secure power supply voltage specified by the
operation manual. Otherwise, fire, ignition, heating, electric
shock, or burn may result.
• Be sure to insert the power plug into the receptacle securely.
Do not use the equipment with the power plug inserted halfway.
• Do not use the equipment in an atmosphere of flammable gas.
Otherwise explosion or fire may result due to ignition.
• Do not touch the live AC adaptor. Otherwise low-temperature
burn may result.
• Do not wet the equipment with water, rain water, or sea water.
Do not use the equipment in wet state or operate it with wet
hands. Do not use the equipment in a high humidity
environment such as bathroom. Otherwise, fire, ignition,
heating, electric shock or injury may result.
• Do not repair, deform, modify, or disassemble the equipment.
Otherwise insufficient insulation may result or the safety device
may be damaged, thus causing fire, ignition, heating, electric
shock, or injury.
• Do not wrap the AC adaptor cord or power cable around the AC
adaptor. Otherwise break or failure may result.
• Do not place a heavy object on the equipment or use it in the
state covered with cloth or quilt. Otherwise heat may
accumulate, thus causing deformation of the case or fire.
• If the equipment is not used for a long period of time, pull the
power cord out of the receptacle. Otherwise ignition or heating
may result.
• Be sure to pull the power plug out of the receptacle before
performing maintenance to ensure safety.

Precautions on battery pack
• Be sure to use the specified battery pack (8PH-4/3A3700-H-
J18).
• Be sure to charge the battery using the Cardimax FX-7102.
Charging the battery using other equipment could lead to a
hazard.
• Do not disassemble or mutilate the battery. You could burn
yourself.
• Do not incinerate or heat the battery. You could burn yourself,
or the battery could burst or leak toxic substances.
• Do not short the battery. You could burn yourself.
• Keep away from children.
• If the liquid contained in the battery gets into your eyes, do not
rub them. Wash your eyes thoroughly with water and see a
doctor immediately.
Nonexplosion proof
Do not operate the FX-7102 in an environment where there is a
risk of explosion. Do not operate the FX-7102 in the presence of
flammable anesthetics.
Magnetic resonance imaging
Do not operate the FX-7102 during Magnetic Resonance Imaging
(MRI) scanning. The conducting current may cause burns.
Operating the FX-7102 may affect the MRI image, while the MRI
may affect the accuracy of the FX-7102.
High-frequency surgery
The patient cable (CP-104T, CP-104L or CP-104J) contains
resistors installed in the lead wire plugs to prevent damage to the
equipment when used in the presence of high frequency surgery
apparatus. These components reduce the risk of not only device
damage, but also the risk of burns to the patient.

WARNING
DANGER
Defibrillation protection
The FX-7102 may remain connected to the patient during
defibrillation only if the proper patient cable provided with
defibrillator protection is being used. The patient cable (CP-
104T, CP-104L or CP-104J) is provided with defibrillation
protection. The FX-7102 will not be damaged when these
cables are used, even if the defibrillator paddles come into
contact with the ECG electrodes.
Connection
• This isolation measure is provided to protect the patient.
Operation is bypassed if the electrodes on the patient cable
come into contact with any other metal object or other
electrically conductive objects, including the operator’s hands.
When such contacts occur, there is a risk of electric shock,
regardless of whether or not the objects are grounded.
• All ECG wires (patient connections), connectors, and amplifiers
are electronically isolated from the rest of the device and from
ground. This isolation restricts the current that can pass
through a patient to less than 10 microamperes.
• If the power supply cords of several different units are
connected together in a multiple outlet tap, an increase in
chassis leakage current can create a potential hazard.
• When a cardiac pacemaker or other electrical stimulator is
connected to the patient, it increases the risk of a potential
hazard. Pay particular attention to safety measures to record
ECG in such conditions. Appropriate measures must be taken
to assure that the chassis leakage current is at a safe level.
• The FX-7102 is Type CF equipment. It must not, however, be
placed in direct contact with the area of the heart.
• Be sure to connect the power supply cord to a hospital-grade
wall AC outlet. If no hospital-grade wall outlet is available,
connect the potential equalization cable securely to a proper
ground. If no proper grounding is available, operate the FX-
7102 on its rechargeable battery.
• In case hum noise is apparent on ECG waveform depending on
the operating environment, connect the equipment to the
ground using potential equalization cable CE-12.
