Introduction
The ZM-940PA/ZM-941PA transmitter transmits ECG, respiration, SpO2, NIBP and pulse waveform
from a patient to a Nihon Kohden monitor for continuous monitoring. The transmitter can change
channels when connected to the QI-901PK channel writer. The front LCD displays SpO2%, NIBP,
pulserate,pulsewaveformamplitude,electrodeconditionmark,batteryconditionandNIBP
measuring mode and interval.
The difference between the ZM-940PA and ZM-941PA is the transmission frequency range.
ZM-940PA:608.0250MHz(channelnumber9002)to613.9750MHz(channelnumber9478)
ZM-941PA:1395.0250MHz(channelnumberE002)to1399.9750MHz(channelnumberE398)
 1427.0250MHz(channelnumberE502)to1431.9750MHz(channelnumberE898)
Read the operator’s manual for the receiving monitor together with this manual before operation.
WARNING
Do not use the same transmitter on
more than one patient at the same
time. Do not connect different sensors
on different patients to the same
transmitter.
CAUTION
• Do not use the same channel for
different patients. If the same
channel is used for two patients, the
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. If a
transmitter of an adjacent channel is
used, radio waves from one
transmitter affect 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.
• For stable signal reception, it is recommended to use a diversity antenna system on the
receiving monitor. 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.
2 Operator’s Manual ZM-940PA/941PA
• NIBP cannot be measured on a neonate. (ECG, respiration and SpO2 can be monitored
on a neonate.)
• Do not diagnose a patient based on only part of the monitoring data on the transmitter or
only on the data acquired by the transmitter. Overall judgement must be performed by a
physician who understands the features, limitations and characteristics of the transmitter
by reading this operator’s manual thoroughly and by reading the biomedical signals
acquired by other instruments.
• For details on the receiving monitor and upgrade information, contact your Nihon Kohden
representative.

WARNING
Before defibrillation, all persons must
keep clear of the bed and must not
touch the patient or any equipment or
cord connected to the patient. Failure
to follow this warning may cause
electrical shock or injury.
WARNING
The following actions must be taken to
properly receive the transmitter signal
of the correct patient on the receiving
instrument. Otherwise, there may be
signal loss or signals may mix causing
a serious accident, such as monitoring
a different patient.
• Assign a channel administrator in
the hospital and only he or she
should manage channel
assignment.
• The channel administrator must
manage the channels in the facility
so that there is no signal
interference.
• When the transmitter channel is
changed, the channel administrator
must check that the channel on the
receiving monitor is also changed
and the signal is properly received.
• The channel administrator must
replace the channel number label
on the transmitter with the new one
after changing the channel.
WARNING
When performing defibrillation,
discharge as far as possible from
electrodes, patches and any gel,
cream or medicine on the chest of the
patient. If there is a possibility that the
defibrillator paddle could touch these
materials, remove them from the
patient. If the defibrillator paddle
directly contacts these materials, the
discharged energy may cause skin
burn to the patient.
WARNING
When the transmitter is used with an
electrosurgical unit (ESU), firmly
attach the entire area of the ESU
return plate. Otherwise, the current
from the ESU flows into the electrodes
of the transmitter, causing electrical
burn where the electrodes are
attached. For details, refer to the ESU
manual.
CAUTION
Do not shake or swing the transmitter
while holding the leads or cables
connected to the transmitter. The
transmitter may come off and injure
someone or damage surrounding
instruments.

WARNING
Never use the transmitter in a
hyperbaric oxygen chamber. Failure to
follow this warning may cause
explosion or fire.
WARNING
When performing MRI test, remove all
electrodes from the patient which are
connected to this transmitter. Failure
to follow this warning may cause skin
burn on the patient. For details, refer
to the MRI manual.
WARNING
When performing defibrillation,
discharge as far as possible from
electrodes, patches and any gel,
cream or medicine on the chest of the
patient. If there is a possibility that the
defibrillator paddle could touch these
materials, remove them from the
patient. If the defibrillator paddle
directly contacts these materials, the
discharged energy may cause skin
burn to the patient.
WARNING
Before defibrillation, all persons must
keep clear of the bed and must not
touch the patient or any equipment or
cord connected to the patient. Failure
to follow this warning may cause
electrical shock or injury.
WARNING
When the transmitter is used with an
electrosurgical unit (ESU), firmly
attach the entire area of the ESU
return plate. Otherwise, the current
from the ESU flows into the electrodes
of the transmitter, causing electrical
burn where the electrodes are
attached. For details, refer to the ESU
manual.
Operator’s Manual ZM-940PA/941PA 11
WARNING
Close the battery case cover during
operation. If the transmitter is used
with the battery case cover open,
anyone who touches the opened
battery case may receive an electrical
shock when defibrillation is performed.
Touching the opened battery case
may cause electrostatic discharge and
intermittently interfere with the
waveform or data.
WARNING
This transmitter is not waterproof. If
detergent or liquid spills into the
transmitter, stop using it and contact
your Nihon Kohden representative. If a
wet transmitter is used, the patient or
operator may receive an electrical
shock or injury.
WARNING

channel is used for two patients, the
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. If a
transmitter of an adjacent channel is
used, radio waves from one
transmitter affect the receiver of the
adjacent channel’s transmitter and
there may be interference.
12 Operator’s Manual ZM-940PA/941PA
CAUTION
Turn off the power of mobile phones,
small wireless devices and other
devices which produce strong
electromagnetic interference around a
patient (except for devices allowed by
the hospital administrator). Radio
waves from devices such as mobile

NIBP Monitoring
WARNING
Be careful when measuring NIBP on a
patient with known bleeding disorders
or coagulation. After NIBP
measurement, there may be dot
hemorrhage, or circulatory disorder by
thrombus where the cuff is attached.
WARNING
NIBP measurement may be incorrect
in the following cases.
• When using an electrosurgical unit
• When there is body movement
• When the pulse wave is small
(insufficient peripheral circulation)
• Too many arrhythmias
• When there is vibration
• When there is a rapid blood
pressure change
• During CPR
WARNING
When performing NIBP
measurements in STAT mode or 5
minute intervals, periodically remove
the cuff from the patient for ventilation.
The skin temperature may increase at
the cuff attachment site by 2 or 3°C (4
or 5°F). When measuring a patient
with a fever or peripheral circulation
insufficiency, it may cause a burn.
Operator’s Manual ZM-940PA/941PA 15
CAUTION
Do not wrap the cuff on an arm or
thigh which is used for injection. NIBP
measurement on an arm or thigh
which is used for injection may cause
reflux of blood and stop injection.
CAUTION
Do not wrap the cuff too tight. It may
cause poor blood circulation and
congestion. If the cuff is wrapped too
loosely, the NIBP value may increase.
CAUTION
Do not attach the cuff to the site
where there is injury or inflammation.
If the skin gets irritated or redness
appears on the skin from the cuff,
change the attachment site or stop
using the cuff. Take extreme care on
the patients with delicate skin.
CAUTION
When using an extension hose, check
that the extension hose is not bent or
squeezed. Otherwise, the cuff might
not inflate or deflate. If the cuff cannot
deflate, it may cause congestion on
the patient at the cuff attachment site.
CAUTION
When performing NIBP measurement
repeatedly, have a rest between
measurements to recover adequate
circulation.
ECG Monitoring
CAUTION
Only use Nihon Kohden specified
electrodes and electrode leads. When
other type of electrodes or electrode
leads are used, the “CHECK
ELECTRODES” message may be
displayed and monitoring may stop.
CAUTION
When the “ELECTRODE OFF” or
“CHECK ELECTRODE” message is
displayed on the receiving monitor,
ECG is not monitored properly and
the ECG alarm does not function.
Check the electrode, electrode leads,
and if necessary, replace with new
ones.
16 Operator’s Manual ZM-940PA/941PA
SpO2 Monitoring
WARNING
SpO2 measurement may be incorrect
in the following cases.
• When the patient’s
carboxyhemoglobin or
methemoglobin increases
abnormally.
• When dye is injected in the blood.
• When using an electrosurgical unit.
• During CPR.
• When measuring at a site with
venous pulse.
• When there is body movement.
• When the pulse wave is small
(insufficient peripheral circulation).
WARNING
• When using the TL-201T finger
probe, do not fasten the probe and
cable to the finger by wrapping with
tape. This may cause burn,
congestion or pressure necrosis
from poor blood circulation.
• When using probes other than the
TL-201T finger probe, to avoid poor
circulation, do not wrap the tape too
tight. Check the blood circulation
condition by observing the skin
color and congestion at the skin
peripheral to the probe attachment
site. Even for short-term monitoring,
there may be burn or pressure
necrosis from poor blood circulation,
especially on neonates or low birth
weight infants whose skin is
delicate. Accurate measurement
cannot be performed on a site with
poor peripheral circulation.
WARNING
When not monitoring SpO2,
disconnect the SpO2 cable from the
transmitter. Otherwise, noise from the
probe sensor may interfere and
incorrect data is displayed on the
screen.
WARNING
Check the circulation condition by
observing the skin color at the
measurement site and pulse
waveform. Change the measurement
site every 8 hours for disposable
probes and every 4 hours for reusable
probes (every 8 hours for TL-630T/TL-
631T series probe). The skin
temperature may increase at the
attached site by 2 or 3°C (4 or 5°F)
and cause a burn or pressure
necrosis. When using the probe on the
following patients, take extreme care
and change the measurement site
more frequently according to
symptoms and degree.
• Patient with a fever
• Patient with peripheral circulation
insufficiency
• Neonate or low birth weight infant
with delicate skin
• Patient who is receiving
photodynamic therapy*
* Photodynamic therapy is a treatment to
remove the affected tissue by using a
photosensitizing agent and exposing the tissue
to light. This treatment has a side effect of
photosensitivityandthelightfromthenger
probe sensor may cause a burn. This probe
uses two light wavelengths in the range from
650 to 950 nm. The maximum light intensity
is less than 5.5 mW/sr.
Operator’s Manual ZM-940PA/941PA 17
CAUTION
NIBP and SpO2 can be measured on
the same limb, but the SpO2
monitoring might not be accurate
during NIBP measurement. Be careful
when reading the SpO2 values.*
* Monitoring SpO2 during NIBP Measurement
When the SpO2 probe is attached to the
same limb as the NIBP cuff, the blood
owdecreasesduringNIBPmeasurement
and pulse wave cannot be detected and
SpO2 cannot be monitored properly. When
“INHIBITSpO2 DURING NIBP” on the
PARAMETER SETUP screen is set to ON
(factory default setting), SpO2 monitoring is
paused during NIBP measurement to avoid
SpO2alarmoccurrence.However,when
monitoring SpO2 on the same limb as the
NIBP, be careful when reading SpO2 values.
CAUTION
While a patient is on medication which
causes vasodilation, the pulse
waveform may change and in rare
cases the SpO2 value might not be
displayed.
CAUTION
Normal external light does not affect
monitoring but strong light such as a
surgical light or sunlight may affect
monitoring. If affected, cover the
measuring site with a blanket.
CAUTION
Do not use a probe which is
deteriorated by aging. Accurate
measurement cannot be performed.
CAUTION
Do not use a damaged or
disassembled probe. It causes
incorrect measurement and may
injure the patient.
CAUTION
The disposable probe is not sterilized.
Use the disposable probe only for a
single patient. Never reuse the
disposable probe for another patient
because it causes cross infection.
CAUTION
If the attachment site is dirty with
blood or bodily fluids, clean the
attachment site before attaching the
probe. If there is nail polish on the
attachment site, remove the polish.
Otherwise, the amount of transmitted
light decreases, and measured value
may be incorrect or measurement
cannot be performed.
CAUTION
If the skin gets irritated or redness
appears on the skin from the probe,
change the attachment site or stop
using the probe. Take extreme care for
the patients with delicate skin.
18 Operator’s Manual ZM-940PA/941PA
CAUTION
Do not pull or bend the probe cable,

probe cable. Do not immerse the
probe cable in chemical solutions or
water. Failure to follow these
instructions may cause cable
discontinuity, short circuit, skin burn
on the patient and incorrect
measurement data. Replace any
broken probe with a new one.
CAUTION
When the probe is attached on an
appropriate site with sufficient
circulation and the error message
confirming the probe attachment
repeatedly appears, the probe may be
deteriorated. Replace it with a new
one.
CAUTION
When a message indicates a faulty
probe, stop monitoring and replace
the probe with a new one.
CAUTION
When removing a probe that is taped
to the skin, do not pull the probe cable
because this can damage the cable.
CAUTION
Neonatal skin is delicate. Remove the
probe and tape carefully and slowly.
CAUTION
When removing the probe from the
attachment tape, do not pull the

INHIBIT SpO2 DURING NIBP
Set whether or not to monitor SpO2 during NIBP measurement.
When the SpO2 probe is attached to the same limb as the NIBP cuff and this setting is set to OFF, the
pulse may become unstable and SpO2 or PR alarm may occur. It is recommended to set this setting
to ON so that SpO2 is not measured during NIBP measurement.
When the SpO2 probe is attached to the other limb from the NIBP cuff, this setting can be set to
OFF.
NOTE
When this “INHIBIT SpO2 DURING NIBP” is set to OFF, refer to the “Monitoring SpO2
during NIBP Measurement” section.

Attaching NIBP Cuff, Electrodes and SpO2 Probe
to the Patient
The transmitter can be attached to an arm of the patient or placed on the bedside. The required
length of the electrode leads and SpO2 probe cable depends on how the transmitter is to be attached
to the patient.
NOTE
Monitoring SpO2 during NIBP Measurement
When the SpO2 probe is attached to the same limb as the NIBP cuff, the blood flow
decreases during NIBP measurement and pulse wave cannot be detected and SpO2
cannot be monitored properly. When “INHIBIT SpO2 DURING NIBP” on the PARAMETER
SETUP screen is set to ON (factory default setting), SpO2 monitoring is paused during
NIBP measurement to avoid SpO2 alarm occurrence. However, when monitoring SpO2 on
the same limb as NIBP, be careful when reading SpO2 values.
When monitoring SpO2 is important, attach the probe to the limb to which the
NIBP cuff or catheter is not attached.
Attachment Examples
When transmitter is attached on an arm When transmitter is placed on a bedside
NOTE
When placing the transmitter on a bedside,
place it on a stable and flat place. If the
transmitter falls off, it may be damaged.

circumference of the upper arm. Refer to the following graph and select the cuff which suits the
patient’s arm.
NOTE
• If a range of arm circumference appropriate for the cuff is prescribed, use a cuff within
that range.
• To obtain accurate measured values, select a wide cuff which can be attached to the
upper arm. Measuring with a very narrow cuff may result in measured values higher than
the actual values.
• The YP-943P NIBP cuff is for standard size adult. Do not use this cuff when it does not fit
the patient.
