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.WARNINGDo 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.WARNINGDo 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/531PACAUTION• 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.CAUTIONSignal 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.૞ᚑ㒙ጊޓᖘᏆ ᛚ⹺⌀ᨩޓ⌬

Operator’s Manual ZM-520PA/521PA/530PA/531PA 11CAUTIONSignal 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.CAUTIONTurn 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.૞ᚑ㒙ጊޓᖘᏆ ᛚ⹺⌀ᨩޓ⌬

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.BatteryWARNINGDo not use NiMH batteries for this transmitter. Some operating environments may cause NiMH batteries to produce gas and explode.CAUTIONBattery 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.CAUTIONWhen the transmitter is not in use, remove the batteries. When the batteries are installed, battery power is consumed even when measurement is not performed.CAUTIONDo not handle the batteries with wet hands.CAUTIONRefer to the battery manual for details on handling the batteries.૞ᚑ㒙ጊޓᖘᏆ ᛚ⹺⌀ᨩޓ⌬
Operator’s Manual ZM-520PA/521PA/530PA/531PA 13Transmitter Channel ManagementWARNINGThe 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 PacemakerWARNINGInteraction 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.

14 Operator’s Manual ZM-520PA/521PA/530PA/531PAECG MonitoringWARNINGAfter 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.WARNINGThe 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.WARNINGThe pacemaker pulse can be overlooked or detected as QRS. You cannot confirm the pacemaker operation only from the detected pacemaker pulse.CAUTIONOnly 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.CAUTIONWhen 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.CAUTIONHold 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.૞ᚑ㒙ጊޓᖘᏆ ᛚ⹺⌀ᨩޓ⌬

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.WARNINGCheck 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૞ᚑ㒙ጊޓᖘᏆ ᛚ⹺⌀ᨩޓ⌬

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.WARNINGCheck 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 skinWARNINGWhen 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.૞ᚑ㒙ጊޓᖘᏆ ᛚ⹺⌀ᨩޓ⌬

64 Operator’s Manual ZM-520PA/521PA/530PA/531PAUse with a PacemakerWhen monitoring a pacemaker patient, the transmitter detects pacemaker pulse and rejects the pacemaker pulse from the heart rate count. WARNINGInteraction 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.htmlWARNINGThe 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.WARNINGThe 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 UnitFor 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.WARNINGWhen 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.NOTENoise 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 noise1. 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.Make smallIncisionReturn plateAs far as possible from electrode andas near as possible to incision.૞ᚑ㒙ጊޓᖘᏆ ᛚ⹺⌀ᨩޓ⌬

The testing was performed during induced hypoxia on healthy 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 measurements.• A pulse oximeter tester that generates simulated signals can be used to check the difference from the design specification, but it cannot be used as a replacement for human signals for testing accuracy.૞ᚑ㒙ጊޓᖘᏆ ᛚ⹺⌀ᨩޓ⌬

Electromagnetic propagation is affected by absorption and reflection from structures, objects and people. *1 Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the ZM-521PA/531PA is used exceeds the applicable RF compliance level above, the ZM-521PA/531PA should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the ZM-521PA/531PA.*2 Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 1 V/m for respiration and 3 V/m for all other functions.૞ᚑ㒙ጊޓᖘᏆ ᛚ⹺⌀ᨩޓ⌬
