To operate the device correctly, read the following precautions carefully.
 The medical institution (hereinafter referred as “Institution”) must decide the
telemetry installation plan for the medical institution in order to prevent
interference and interference between transmitters (telemetry based on
destination country’s radio law).
 When using telemetry which requires zone location, the institution is to set
up the zones as an operation unit for each transmitter to prevent electronic
interference between telemetry throughout the medical institution.
 When using telemetry which requires zone location, display and identify
each prepared zone in the equipment.
 When laying receiver antenna for each transmitter, the institution has to be
examined so as not to generate electronic interference.
 Based on the above examination result, the institution places each receiver
antenna as required.
In managing, be sure to follow the precautions below.
 The institution appoints a person to manage the wireless channels for the
whole medical institution. And when using telemetry which requires zone
location, the institution nominates a person to manage the wireless
channels in each zone (a “Zone Manager”). However, when using such
telemetry in a local medical institution, one person can perform both
functions.
 Select a telemetry manager who understands the characteristics and
functionality of telemetry systems, and is skilled in operating telemetry.
 When installing telemetry, the Overall Manager and the Zone Manager
have to understand the precautions for use of the telemetry in advance.
 The Overall Manager takes responsibility of wireless channel management
and transmitter storage for the whole medical institution by giving proper
instruction.
 The Overall Manager creates a management log, list of wireless channels,
management status for the whole medical institution (hereinafter referred to
as the “management log”). When changing a wireless channel, register it in
the log and give proper instructions to the zone manager or to the user.
 The Zone Manager assumes responsibility for managing the wireless

xi

Precautions about the Pacemaker
WARNING
 Minute ventilation rate-adaptive implantable pacemakers can
occasionally interact with certain cardiac monitoring and diagnostic
equipment, causing the pacemakers to pace at their maximum
programmed rate. The cardiac monitoring and diagnostic equipment may
possibly send wrong information.
If such event occurs, please disconnect the cardiac monitoring and
diagnostic equipment, or follow the procedures described in the operation
manual of the pacemaker.
(For more details, contact FUKUDA DENSHI personnel, your institution’s
professionals, or your pacemaker distributors.)
Reference
“Minute Ventilation Rate-Adaptive Pacemakers”
FDA alerts health professionals that minute ventilation
rate-adaptive implantable pacemakers can occasionally interact
with certain cardiac monitoring and diagnostic equipment, causing
pacemakers to pace at their maximum programmed rate.
[October 14, 1998 (Letter: www .fda.gov/cdrh/safety.html) – FDA]
 Rate meters may continue to count the pacemaker rate during
occurrences of cardiac arrest or some arrhythmias. Do not rely entirely
upon rate meter alarms. Keep pacemaker patients under close
surveillance. See this manual for disclosure of the pacemaker pulse
rejection capability of this equipment.
Non-Explosion Proof
DANGER Never operate the equipment in the presence of flammable anesthetics, high
concentration of oxygen, or inside hyperbaric chamber. Also, do not operate
the equipment in an environment in which there is a risk of explosion.
Explosion or fire may result.
Defibrillation Safety
WARNING
 When using the defibrillator, keep away from the electrodes or
medicament applied to the patient chest. If this is not possible, remove
the electrodes or medicament before using it.
If the defibrillator paddles are directly in contact with the electrodes or
medicament, electrical shock may result by the discharged energy.
 When using the defibrillator, make sure that the electrodes, sensor
cables, or relay cables are firmly connected to the device.
Contacting the metal part of the disconnected cable may result in
electrical shock by the discharged energy.
 When using the defibrillator, do not touch the patient and the metal part of
the device or cables. Electric shock may result by the discharged energy.
xii

Electrosurgery Safety
WARNING
The monitoring system contains protection against interference generated by
electrosurgical instruments. However, operating conditions, surgery site with
respect to the location of ECG electrodes, or the type of instrument used, may
cause noise on the ECG. The noise is generated at the tip of an electrical knife
and is difficult to completely eliminate because of the frequency components of
the ECG. To reduce electrosurgical interference, take the following
precautions:
Location
Locate the electrosurgical unit as far as possible from this unit and the
patient cable. This will help reduce interference on the ECG through the
monitor or cables.
Power Supply
Connect the electrosurgical unit to a power supply that is different from that
of the monitor. This will help prevent interference through the power cable.
Electrode Placement
The amount of interference is considerably different depending on the
electrode position and surgery site. Place the ECG electrodes as far away
as possible from the surgery site and the ground plate. Do not place
electrodes in the path between the surgery site and the ground plate. If the
electrodes are placed in this path, the amount of interference will be quite
large. Position (+) and (–) electrodes as close as possible to each other.
Ground Plate
When using electrosurgical instruments, make sure the contact between
the patient and the ground plate is secure. If the connection is incomplete,
the patient may suffer a burn at the electrode site.
Precautions about Magnetic Resonance Imaging
WARNING
 Do not operate this equipment in magnetic resonance imaging (MRI)
environments.
 When conducting MRI test, remove the electrodes and sensors connected
to the patient (test subject).
The local heating caused by the induced electromotive force may cause
burn injury to the patient (subject). For details, refer to the operation
manual for the MRI testing device.
xiii

Precautions about Connections to Peripheral Devices
In the interest of safe and sufficient performance of this equipment, the connection of other
manufacturers’ equipment to the monitor is not authorized, unless the connection is explicitly
approved by Fukuda Denshi. It is the user’s responsibility to contact Fukuda Denshi to determine
the compatibility and warranty status of any connection made to another manufacturer’s equipment.
WARNING For the connector with mark, only the peripheral devices specified by
Fukuda Denshi should be connected with the given procedure. Use of an
unspecified device may cause electric shock to the patient and/or operator due
to excessive leakage current.
CAUTION All the peripheral device connectors on the DS-7000 are isolated from the
power supply, but the peripheral devices are not isolated. To prevent danger of
electric shock, always position the peripheral devices away from the patient.
When connecting peripheral devices to DS-7000, it is the user’s responsibility to verify that the
overall system complies with IEC 60601-1-1, “Collateral Standard: Safety Requirements for
Medical Electrical Systems”.
Precautions about the Fuse
DANGER If the fuse blows, do not continue using it as internal damage to the equipment
may be considered.

 The DS-7000 is not a life-support equipment.
 The DS-7000 is not intended for use during patient transport outside a
healthcare facility, and is not considered as mobile or portable equipment.
 The DS-7000 is not intended for use with flammable anesthetic agents.
 Do not connect unit or cable not authorized by Fukuda Denshi to any I/O
connector. If done so by mistake, the DS-7000 cannot deliver its maximum
performance and the connected units may be damaged, resulting in a
safety hazard.
 If the DS-7000 is used under an environment not fulfilling the specified
condition, not only that the equipment cannot deliver its maximum
performance, the equipment may be damaged and safety cannot be
ensured.
 Use only the accompanying 3-way AC power cable. Use of other cables
may result in electric shock to the patient and the operator.
 The power cable must be connected to hospital grade outlet.
 When using multiple ME equipment simultaneously, perform equipotential
grounding to prevent potential difference between the equipment. Even a
small potential difference may result in electric shock to the patient and the
operator.
 Make sure to set the patient classification and pacemaker usage. These
settings influence the precision of the QRS detection and NIBP
measurement. Make sure the correct selection is made.
 The pacemaker usage selection influences the precision of the QRS
detection and arrhythmia analysis. Make sure the correct selection is made.
 If the QRS pace pulse mask function is set to OFF , 10ms or 20ms ,
a decrease in heart rate may not generate HR or ASYSTOLE alarms by
erroneously detecting pacemaker pulse as QRS. Set this function to
OFF , 10ms or 20ms only if you are sure that pacing failure will not
occur, or when the patient can be constantly monitored.
 When measuring the SpO2of patient with high fever or peripheral
circulatory insufficiency, check the sensor attachment periodically and
change the attachment site. The temperature of attachment site will rise 2to
3°C due to the sensor heat which may result in burn injury.
 For the following case, accurate measurement may not be possible.
 Patient with excessive abnormal hemoglobin (COHb, MetHb)
 Patient with the pigment injected to the blood
 Patient receiving CPR treatment
 When a sensor is applied to a limb with NIBP cuff, arterial catheter, or
intracatheter
 When measuring at site with venous pulse
 Patient with body motion
 Patient with small pulse
 Be cautious when setting the "SpO2Averaging" duration as the SpO2alarm
is based on the displayed SpO2value which is averaged from the duration
set in "SpO2Averaging". The alarm occurrence time will be affected or may
not occur for the transient value of SpO2depending on the set duration.
 Before the measurement, make sure the patient classification ( Adult /
Child / Neonate ) is properly selected. Otherwise, correct
measurement cannot be performed, and congestion or other injury may
result.
 When monitoring multigas concentration, use the specified water trap.
xv

WARNING
 When using the airway adapter, always consider the circumference of the
intubation tube. If inappropriate airway adapter is used for a patient with
low ventilation, CO2may mix in to the inspired air resulting in incorrect
measurement, or apnea detection may become difficult.
 When multigas unit (MGU-701/MGU-702/Poet IQ) is used, the sampling
tube may get clogged by the internal condensation.
 If the upper/lower alarm limit of the parameter is set to OFF, or arrhythmia
alarm is set to OFF, alarm will not function even if the system alarm is set to
ON. Pay attention when setting them OFF.
 Objective and constant arrhythmia detection is possible through the fixed
algorithm incorporated in this monitor. However, excessive waveform
morphology change, motion artifact, or the inability to determine the
waveform pattern may cause an error, or fail to make adequate detection.
Therefore, physicians should make final decisions using manual recording,
alarm recording and recall waveform for evaluation.
 The HR/PR alarm will not be generated unless the numeric data box
corresponded to the selected HR/PR alarm source is displayed. When
HR/PR alarm source selection is changed, be sure to display the numeric
data box corresponded to the selected HR/PR source.
 The RR and apnea alarm will not be generated unless the numeric data
box corresponded to the selected RR source is displayed. If the RR source
is changed, make sure to display the numeric data box corresponded to the
RR source.
 When selecting Silence or Time Only for the night mode, pay
attention not to miss any important alarm by simultaneously monitoring the
bed on other monitors such as central monitor.
 When lifting this device, hold the bottom part of the main unit and not the
display unit.
 About the Air Filter for Cooling Fan (DS-7000, MGU-701, MGU-702)
 When the air filter is washed with neutral detergent, dry it completely
