GENERAL HANDLING PRECAUTIONS
This device is intended for use only by qualified medical personnel.
Use only Nihon Kohden approved products with this device. Use of
non-approved products or in a non-approved manner may affect the
performance specifications of the device. This includes, but is not
limited to, batteries, recording paper, pens, extension cables,
electrode leads, input boxes and AC power.
Please read these precautions thoroughly before attempting to operate
the instrument.
1. To safely and effectively use the instrument, its operation must be
fully understood.
2. When installing or storing the instrument, take the following
precautions:
(1) Avoid moisture or contact with water, extreme atmospheric
pressure, excessive humidity and temperatures, poorly ventilated
areas, and dust, saline or sulphuric air.
(2) Place the instrument on an even, level floor. Avoid vibration and
mechanical shock, even during transport.
(3) Avoid placing in an area where chemicals are stored or where there
is danger of gas leakage.
(4) The power line source to be applied to the instrument must
correspond in frequency and voltage to product specifications, and
have sufficient current capacity.
(5) Choose a room where a proper grounding facility is available.
3. Before Operation
(1) Check that the instrument is in perfect operating order.
(2) Check that the instrument is grounded properly.
(3) Check that all cords are connected properly.
(4) Pay extra attention when the instrument is in combination with
other instruments to avoid misdiagnosis or other problems.
Operator's Manual ZS-910PA i
(5) All circuitry used for direct patient connection must be doubly
checked.
(6) Check that battery level is acceptable and battery condition is good
when using battery-operated models.
4. During Operation
(1) Both the instrument and the patient must receive continual, careful
attention.
(2) Turn power off or remove electrodes and/or transducers when
necessary to assure the patient’s safety.
(3) Avoid direct contact between the instrument housing and the
patient.
5. To Shutdown After Use
(1) Turn power off with all controls returned to their original positions.
(2) Remove the cords gently; do not use force to remove them.
(3) Clean the instrument together with all accessories for their next
use.
6. The instrument must receive expert, professional attention for
maintenance and repairs. When the instrument is not functioning
properly, it should be clearly marked to avoid operation while it is
out of order.
7. The instrument must not be altered or modified in any way.
8. Maintenance and Inspection:
(1) The instrument and parts must undergo regular maintenance
inspection at least every 6 months.
(2) If stored for extended periods without being used, make sure prior
to operation that the instrument is in perfect operating condition.
(3) Technical information such as parts list, descriptions, calibration
instructions or other information is available for qualified user
technical personnel upon request from your Nihon Kohden
distributor.
ii Operator's Manual ZS-910P A
9. When the instrument is used with an electrosurgical instrument,
pay careful attention to the application and/or location of electrodes
and/or transducers to avoid possible burn to the patient.
10. When the instrument is used with a defibrillator, make sure that the
instrument is protected against defibrillator discharge. If not,
remove patient cables and/or transducers from the instrument to
avoid possible damage.
WARRANTY POLICY
Nihon Kohden Corporation (NKC) shall warrant its products against all
defects in materials and workmanship for one year from the date of delivery.
However, consumable materials such as recording paper, ink, stylus and
battery are excluded from the warranty.
NKC or its authorized agents will repair or replace any products which
prove to be defective during the warranty period, provided these products
are used as prescribed by the operating instructions given in the operator’s
and service manuals.
No other party is authorized to make any warranty or assume liability for
NKC’s products. NKC will not recognize any other warranty, either implied
or in writing. In addition, service, technical modification or any other
product change performed by someone other than NKC or its authorized
agents without prior consent of NKC may be cause for voiding this
warranty.
Defective products or parts must be returned to NKC or its authorized
agents, along with an explanation of the failure. Shipping costs must be prepaid.
This warranty does not apply to products that have been modified,
disassembled, reinstalled or repaired without Nihon Kohden approval or
which have been subjected to neglect or accident, damage due to accident,
Operator's Manual ZS-910PA iii
fire, lightning, vandalism, water or other casualty, improper installation or
application, or on which the original identification marks have been
removed.
In the USA and Canada other warranty policies may apply.
CAUTION
United States law restricts this device to sale by or on the order
of a physician.
Equipment Authorization Requirement
Operation of this equipment requires the prior coordination with a frequency
coordinator designated by the FCC for the Wireless Medical Telemetry
Service.
iv Operator's Manual ZS-910P A
EMC RELA TED CAUTION
This equipment and/or system complies with the International
Standard IEC60601-1-2 for electromagnetic compatibility for
medical electrical equipment and/or system. However, an
electromagnetic environment that exceeds the limits or levels
stipulated in the IEC60601-1-2, can cause harmful interference to
the equipment and/or system or cause the equipment and/or
system to fail to perform its intended function or degrade its
intended performance. Therefore, during the operation of the
equipment and/or system, if there is any undesired deviation
from its intended operational performance, you must avoid,
identify and resolve the adverse electromagnetic effect before
continuing to use the equipment and/or system.
The following describes some common interference sources and
remedial actions:
1.Strong electromagnetic interference from a nearby emitter
source such as an authorized radio station or cellular phone:
Install the equipment and/or system at another location if it is
interfered with by an emitter source such as an authorized
radio station. Keep the emitter source such as cellular phone
away from the equipment and/or system.
2.Effect of direct or indirect electrostatic discharge:
Make sure all users and patients in contact with the equipment
and/or system are free from direct or indirect electrostatic
energy before using it. A humid room can help lessen this
problem.
3.Electromagnetic interference with any radio wave receiver
such as radio or television:
If the equipment and/or system interferes with any radio wave
receiver, locate the equipment and/or system as far as
possible from the radio wave receiver.
Operator's Manual ZS-910PA v
If the above suggested remedial actions do not solve the
problem, consult your Nihon Kohden Corporation subsidiary or
distributor for additional suggestions.

Introduction
The ZS-910PA transmits ECG from a patient to a Nihon Kohden monitor.
The transmitter can change channels when connected to the QI-901PK
channel writer. Read the operator’s manual for the monitor together with this
manual before operation.
CAUTION
••
• Do not use the same channel for different patients. Otherwise,
••
two patients’ data will be lost due to mutual modulation
interference, or another patient’s data may appear on the
receiving monitor screen.
••
• Do not use transmitters of adjacent channels in a hospital.
••
Otherwise, radio waves from one transmitter affects the receiver
of the adjacent channel’s transmitter and there may be
interference.
NOTE
••
• To prevent interference between channels, assign a channel
••
administrator in the hospital and only he or she should manage
channel assignment.
••
• Use Nihon Kohden parts and accessories to assure maximum
••
performance from your instrument.
••
• It is recommended to use a diversity antenna system on the
••
receiving monitor for stable signal reception. Otherwise, spike
noise from transient fading of electric field strength (for example,
people moving) may interfere with the transmitter signal and may
be mistaken as an arrhythmia on the receiving monitor.

Connects the electrode lead.
WARNING
••
• Before performing defibrillation, check that the electrode leads
••
attached to the patient are properly connected to the transmitter.
Touching the metal parts of disconnected leads and probes
causes serious electrical shock or injury by discharged energy.
••
• When performing defibrillation, all persons must keep clear of the
••
bed and must not touch the patient, any equipment connected to
the patient or the metal parts of leads connected to the patient.
Failure to follow this warning may result in serious electrical burn,
shock or other injury.
