Intended Use
General
The ZM-520PA and ZM-521PA transmitter transmits ECG and respiration from a patient to a
Nihon Kohden monitor for continuous monitoring. The front LCD displays ECG, numeric values
of monitoring parameters, messages and battery condition.* It also displays the compressed
waveform and numeric data of the latest 10 minutes.
The ZM-530PA and ZM-531PA transmitter transmits ECG, respiration and pulse waveforms
and SpO2 from a patient to a Nihon Kohden monitor for continuous monitoring. The front LCD
displays ECG (or pulse wave), numeric values of monitoring parameters, messages and battery
condition.* It also displays the compressed waveform and numeric data of the latest 10 minutes.
* Essential performance of this transmitter.
The difference between the ZM-520PA/530PA and ZM-521PA/531PA is the transmission
frequency range.
ZM-520PA/530PA: 608.0250 MHz (channel number 9002) to 613.9750 MHz (channel number
9478)
ZM-521PA/531PA: 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)
The transmitter channel can be changed with a QI-901PK channel writer.
Read the operator’s manual for the receiving monitor together with this manual before use.
WARNING
Do not diagnose a patient based only on data acquired by the transmitter. Overall
judgement must be performed by a physician who understands the features,
limitations and characteristics of the transmitter and by reading the biomedical
signals acquired by other instruments.
WARNING
Do not use the same transmitter for more than one patient at the same time. Do not
connect different sensors from different patients to the same transmitter.
ᚑ㒙ጊޓᖘᏆ ᛚ⌀ᨩޓ⌬
2 Operator’s Manual ZM-520PA/521PA/530PA/531PA
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 two transmitters with adjacent channels in the same hospital. If
transmitters with adjacent channels are used, their radio waves interfere with each
other.
CAUTION
Signal loss and artifact may occur because of the multipath cancellation* when using
a transmitter.
* Multipath Cancellation (Standing Wave Interference):
When a radio wave reflects off a surface, there may be some points in the room where the
reflected and direct waves are exactly out of phase. At these points in the room, the reflected
and direct waves cancel each other out so that the signal strength is decreased. Locations where
signal loss occurs are called “null spots”. If the transmitter is moving or nearby people or
objects are moving, null spots can occur anytime and anywhere.
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.
• For details on antennas and antenna construction, contact your Nihon Kohden
representative. You can also refer to the Telemetry System Installation Guide.

Receiving Monitor
Any Nihon Kohden receiving monitor (central monitor with multiple patient receiver) can receive
signals from this transmitter as long as the protocol version and channel setting are the same on
the receiving monitor and transmitter.
NOTE
• For details on the receiving monitor and upgrade information, contact your Nihon
Kohden representative.
• The transmitter does not give any alarm other than a “no battery” alarm. Alarms must
be managed on the receiving monitor.
• To use protocol 51, the ORG-9100A/ORG-9110A multiple patient receiver software
version 03-03 or later is required. For the protocol setting, refer to the “Changing

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 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
Do not diagnose a patient based only
on data acquired by the transmitter.
Overall judgement must be performed
by a physician who understands the
features, limitations and characteristics
of the transmitter and by reading the
biomedical signals acquired by other
instruments.
CAUTION
Only use Nihon Kohden specified
electrodes, electrode leads and SpO2
probes. Otherwise, the maximum
performance from the transmitter
cannot be guaranteed.
CAUTION
Do not reuse disposable parts and
accessories.
CAUTION
The measurement values and
displayed waveforms on the transmitter
and receiving monitor may be different
due to timing delay of the display or
difference in detection settings.
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.
ᚑ㒙ጊޓᖘᏆ ᛚ⌀ᨩޓ⌬
Operator’s Manual ZM-520PA/521PA/530PA/531PA 11
CAUTION
Signal loss and artifact may occur
because of the multipath cancellation*
when using a transmitter.
* Multipath Cancellation (Standing Wave
Interference):
When a radio wave reflects off a surface,
there may be some points in the room where
the reflected and direct waves are exactly
out of phase. At these points in the room, the
reflected and direct waves cancel each other
out so that the signal strength is decreased.
Locations where signal loss occurs are called
“null spots”. If the transmitter is moving or
nearby people or objects are moving, null
spots can occur anytime and anywhere.
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
phones or small wireless devices may
be mistaken as pulse waves or
respiration waves and the displayed
data may be incorrect.
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 two transmitters with
adjacent channels in the same
hospital. If transmitters with adjacent
channels are used, their radio waves
interfere with each other.

Output Signal
WARNING
Do not use the output signal from the receiving monitor as the synchronization signal
for other equipment such as IABP, MRI, echocardiography or defibrillator. There may
be time delay between the monitor and the other equipment caused by waveform
transmission delay and spike noise may interfere on the output signal and be
mistaken as a trigger.
Battery
WARNING
Do not use NiMH batteries for this
transmitter. Some operating
environments may cause NiMH
batteries to produce gas and explode.
CAUTION
Battery replacement must be
performed by the operator. When
replacing the batteries of a transmitter
that is currently used for a patient,
disconnect the electrode leads from
the transmitter before replacing
batteries or do not touch the patient
during replacement.
CAUTION
When the transmitter is not in use,
remove the batteries. When the
batteries are installed, battery power is
consumed even when measurement is
not performed.
CAUTION
Do not handle the batteries with wet
hands.
CAUTION
Refer to the battery manual for details
on handling the batteries.

Transmitter Channel Management
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.
For Patients Using Implantable Pacemaker
WARNING
Interaction Between Minute Ventilation Rate-Adaptive Pacemakers and Cardiac
Monitoring and Diagnostic Equipment*
The bioelectric impedance measurement sensor of a minute ventilation rate-adaptive
implantable pacemaker may be affected by transmitter which is connected to the
same patient. If this occurs, the pacemaker may pace at its maximum rate and the
transmitter may give incorrect data to the monitor. If this occurs, disconnect the
electrode leads from the patient or change the setting on the pacemaker by referring
to the pacemaker’s manual. For more details, contact your pacemaker representative
or Nihon Kohden representative.
* Minute ventilation is sensed in rate-adaptive pacemakers by a technology known as bioelectric
impedance measurement (BIM). Many medical devices in addition to pacemakers use this
technology. When one of these devices is used on a patient with an active, minute ventilation
rate-adaptive pacemaker, the pacemaker may erroneously interpret the mixture of BIM signals
created in the patient, resulting in an elevated pacing rate.
For more information, see the FDA web site.

ECG Monitoring
WARNING
After attaching the electrode to the
patient and connecting the electrode
lead to the transmitter, check that
electrodes are attached to the patient
and check that the electrode lead is
connected to the transmitter properly.
When the electrodes are removed from
the patient, do not touch the metal part
of the electrode with bare hands or let
the metal part of the electrode contact
the metal part of the bed or any other
conductive parts. Failure to follow this
warning may cause electrical shock or
injury to the patient by discharged
energy.
WARNING
The transmitter detects the pacemaker
pulse and rejects the pacemaker pulse
from the heart rate count. However, all
of the pacemaker pulse might not be
rejected. If the pacemaker pulse is not
rejected, the pacemaker pulse is
detected as QRS and false heart rate
may be indicated. Keep pacemaker
patients under close observation.
* For the pacemaker pulse rejection capability
of ZM-520PA/521PA/530PA/531PA
transmitter refer to the “Specifications -
ECG” section.
WARNING
The pacemaker pulse can be
overlooked or detected as QRS. You
cannot confirm the pacemaker
operation only from the detected
pacemaker pulse.
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 ECG monitoring may
stop.
CAUTION
When the “ELECTRODE OFF” or
“CHECK ELECTRODES” 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.
CAUTION
Hold the connector of the electrode
lead when connecting/disconnecting
the electrode lead. If you disconnect
the electrode lead by pulling the lead, it
damages the electrode lead.

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 monitoring SpO2 of a patient
who is receiving photodynamic therapy,
the light from the finger probe sensor
may cause a burn. Photodynamic
therapy uses a photosensitizing agent
that has a side effect of
photosensitivity.
The SpO2 probe manufactured by Nihon
Kohden have two wavelengths with peaks in the
range of 650 and 950 nm. The maximum light
intensity is less than 5.5 mW.
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
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-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 insufficient peripheral
circulation
• Neonate or low birth weight infant
with delicate skin

is displayed on the screen.
CAUTION
Refer to the probe instruction manual
for details.
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
Do not attach the probe to the same
limb that is used for NIBP
measurement or an IBP catheter. The
SpO2 measurement may be incorrect.
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
When a message indicates a faulty
probe, stop monitoring and replace the
probe with a new one.
CAUTION
Do not use a damaged or
disassembled probe. It causes

Attaching the Probe to the Patient
Attach the probe to the patient by referring to the probe’s manual. Make sure that the light emitter
and photo detector of the probe face each other at the attachment site.
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
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-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 insufficient peripheral
circulation
• Neonate or low birth weight infant
with delicate skin
WARNING
When monitoring SpO2 of a patient
who is receiving photodynamic therapy,
the light from the finger probe sensor
may cause a burn. Photodynamic
therapy uses a photosensitizing agent
that has a side effect of
photosensitivity.
The SpO2 probe manufactured by Nihon
Kohden have two wavelengths with peaks in the
range of 650 and 950 nm. The maximum light
intensity is less than 5.5 mW.

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
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
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.
CAUTION
Do not use a probe which is
deteriorated by aging. Accurate
measurement cannot be performed.
CAUTION
Refer to the probe instruction manual

Use with a Pacemaker
When monitoring a pacemaker patient, the transmitter detects pacemaker pulse and rejects the
pacemaker pulse from the heart rate count.
WARNING
Interaction Between Minute Ventilation Rate-Adaptive Pacemakers and Cardiac
Monitoring and Diagnostic Equipment*
The bioelectric impedance measurement sensor of a minute ventilation rate-adaptive
implantable pacemaker may be affected by transmitter which is connected to the
same patient. If this occurs, the pacemaker may pace at its maximum rate and the
transmitter may give incorrect data to the monitor. If this occurs, disconnect the
electrode leads from the patient or change the setting on the pacemaker by referring
to the pacemaker’s manual. For more details, contact your pacemaker representative
or Nihon Kohden representative.
* Minute ventilation is sensed in rate-adaptive pacemakers by a technology known as bioelectric
impedance measurement (BIM). Many medical devices in addition to pacemakers use this
technology. When one of these devices is used on a patient with an active, minute ventilation
rate-adaptive pacemaker, the pacemaker may erroneously interpret the mixture of BIM signals
created in the patient, resulting in an elevated pacing rate.
For more information, see the FDA web site.
http://www.fda.gov/cdrh/safety.html
WARNING
The transmitter detects the pacemaker pulse and rejects the pacemaker pulse from
the heart rate count. However, all of the pacemaker pulse might not be rejected. If
the pacemaker pulse is not rejected, the pacemaker pulse is detected as QRS and
false heart rate may be indicated. Keep pacemaker patients under close observation.
* For the pacemaker pulse rejection capability of ZM-520PA/521PA/530PA/531PA transmitter
refer to the “Specifications - ECG” section.
WARNING
The pacemaker pulse can be overlooked or detected as QRS. You cannot confirm
the pacemaker operation only from the detected pacemaker pulse.
NOTE
• If an electric blanket is used and incorrect heart rate is displayed on the monitor, turn
off the pacing spike detection on the monitor.
ᚑ㒙ጊޓᖘᏆ ᛚ⌀ᨩޓ⌬
Operator’s Manual ZM-520PA/521PA/530PA/531PA 65
• Turn the pacing spike detection to ON on the receiving monitor when monitoring a
pacemaker patient. Pacing pulse is detected by the transmitter and transmitted to the
monitor. If the pacing spike detection is turned OFF, QRS and pacemaker spike might
not be distinguished and pacemaker failure might not be recognized.
Use with an Electrosurgical Unit
For use with an electrosurgical unit (ESU), this transmitter has a circuit to protect the patient from
skin burn and to reduce ESU interference on the ECG waveform. However, the effectiveness of
this circuit depends on electrode position and transmitter setup. With an ESU, pay attention to the
following points.
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.
NOTE
Noise generated from an electrosurgical unit may interfere on an ECG waveform, but will
not damage it.
• Measure with 3-electrode lead
Use the minimum number of electrodes. Use new electrodes.
• Minimize noise
1. Select an ECG lead where the active ECG electrodes are located as far from the incision as
possible.
2. Position the + and – electrodes as close as possible.
3. Select the leads where the angle (θ) between the active electrodes and the incision is as small
as possible.
4. Set the electrosurgical return plate as close to the incision as possible.

volunteers (Ethnicity: 10 Caucasians, 2 Africans, 1 Asian and 3 Indians), (Skin: 8 light,
4 medium, 4 dark), (Age: 21 to 34), (5 women and 11 men) under the condition of no
motion. Arterial blood was sampled and measured by a CO-oximeter. The difference
between SpO2 measured by the SpO2 probe and functional SaO2 measured by a
CO-oximeter was calculated using the root-mean-square (rms) method according
to ISO 9919: 2005. This measurement accuracy figure represents 2/3 of all test

Avoiding Electromagnetic Interference (Impedance Respiration)
Impedance respiration measurement is very sensitive and affected by electromagnetic
interference. Technological limitations do not allow immunity levels higher than 1 V/m for
radiated RF electromagnetic fields. Electromagnetic fields with field strengths above 1 V/m
may cause measurement error. Do not use electrically radiating equipment near the impedance
respiration measurements.

volunteers (Ethnicity: 10 Caucasians, 2 Africans, 1 Asian and 3 Indians), (Skin: 8 light,
4 medium, 4 dark), (Age: 21 to 34), (5 women and 11 men) under the condition of no
motion. Arterial blood was sampled and measured by a CO-oximeter. The difference
between SpO2 measured by the SpO2 probe and functional SaO2 measured by a
CO-oximeter was calculated using the root-mean-square (rms) method according
to ISO 9919: 2005. This measurement accuracy figure represents 2/3 of all test
