Indications for Use1-2 Introduction to the HP Telemetry SystemIndications for UseThe paragraphs below are the elements of the indications for use statement for the HP Telemetry System, which consists of the HP Viridia Telemetry System (M2600A) and the HP Digital UHF Telemetry System (M1403A) with Option C03.Condition The licensed clinician decides that the HP Telemetry System should be used to monitor the patient.PrescriptionVersus Over-the-CounterThe HP Telemetry System is a prescription device.Part of theBody or Typeof Tissue withwhich theDeviceInteractsThe ECG signal is obtained from accessory electrodes in contact with the patient’s skin. The SpO2 signal is obtained from an accessory sensor in contact with the patient’s skin.Frequency ofUse The HP Telemetry System is indicated for use when prescribed by a licensed clinician.PhysiologicalPurpose The HP Telemetry System is indicated when the physiological purpose is to monitor the ECG or SpO2 of patients on the order of a licensed clinician.PatientPopulation Adult and pediatric patients.

Indications for UseIntroduction to the HP Telemetry System 1-31 System IntroductionIntended Use The HP Telemetry System is a comprehensive ambulatory system solution for the intermediate care unit for adult and pediatric patients. The foundation of the system is a transmitter that can capture and transmit ECG signals and SpO2 values (if available) that are then processed and displayed on the HP Viridia Information Center. The information center generates alarms and recordings, thus notifying clinicians of changes in patients’ conditions. The Telemetry System communicates with other devices via the HP Viridia monitoring network. Note—SpO2 monitoring is only available with the HP Viridia Transmitter.WarningUnited States law restricts this device to sale by or on the order of a physician. This product is intended for use in health care facilities by trained health care professionals. It is not intended for home use.

System Overview1-4 Introduction to the HP Telemetry SystemSystem OverviewThe HP Telemetry System includes the HP M2600A Viridia Telemetry System and/or the HP M1403A Digital UHF Telemetry System with Option C03. The Telemetry System is used with the HP Viridia Information Center to provide multi-parameter measurements for transitional care and other ambulatory monitoring environments. The system:• Monitors adult and pediatric patients’ ECG.• Measures pulsatile arterial oxygen saturation (SpO2) and pulse rate.• Enables viewing of ECG and SpO2 measurements and waveforms at the patient’s side.• Makes ST segment measurements.The HP Telemetry System consists of:• A transmitter for each patient. • An antenna system.• A receiver for each transmitter.• A mainframe housing up to eight receivers.• An HP Palmtop Personal Computer with HP Wave Viewer software (for use with Viridia transmitters only). See “Introducing the HP Viridia Wave Viewer” on page 5-5 for additional informationDual-bandOperation In Release B, the frequency range of the HP Viridia Telemetry System (M2600A) has been expanded to allow operation in the 590-632 MHz frequency band in addition to the current band of 406-480 MHz. This enhancement is for use in countries where radio rule changes have made a higher band more desirable for providing operating frequencies for medical telemetry. For example, in the U.S.A., a FCC rule change provides primary operation for medical telemetry at UHF TV Channel 37 (608-614 MHz). A new antenna system, which is backwards compatible with existing systems, enables operation to 650 MHz, addressing the needs of these new rules, and allows operation of transmitters in both bands simultaneously.

Transmitters1-6 Introduction to the HP Telemetry SystemTransmittersThe following transmitters can be used with the HP Telemetry System:• HP Viridia Transmitter (ECG/SpO2 or ECG-only versions). • HP M1400A/B Transmitter (ECG only)WarningPacemakers can be susceptible to radio frequency (RF) interference from devices such as telemetry transmitters which may temporarily impair their performance.The output power of telemetry transmitters and other sources of radio frequency energy, when used in the proximity of a pacemaker, may be sufficient to interfere with the pacemaker’s performance. Due to the shielding effects of the body, internal pacemakers are somewhat less vulnerable than external pacemakers. However, caution should be exercised when monitoring any paced patient. In order to minimize the possibility of interference, position electrodes, electrode wires, and the transmitter as far away from the pacemaker as possible. See the HP Viridia Information Center User’s Guide for additional information on monitoring paced patients. HP Viridia Transmitter The HP Viridia Transmitter is battery powered and worn by the patient. It acquires the patient’s ECG and SpO2 signals (if available), processes them, and sends them via the antenna system to the receiver. Measurements are then displayed at the HP Viridia Information Center. The transmitter can also be connected via an infrared link to the HP Viridia Wave Viewer on a HP palmtop computer to provide display of patient measurements and waveforms at the patient’s side.

TransmittersIntroduction to the HP Telemetry System 1-71 System IntroductionECG Connection: The Viridia Transmitter supports a 3- or 5-wire ECG cable compatible with HP Viridia CMS/24 ECG trunk cables. CMS trunk cables must include telemetry combiners. In addition to keeping dirt out of the connectors, the combiner has a locking mechanism to keep the lead set attached securely to the transmitter. For safety, every lead should be secured to an electrode on the patient. Disconnection of Leadset: When you’re ready to disconnect the leadset, lift the clip of the combiner to release the lock. Then, holding the combiner firmly, rock the leadset free. Do not pull on the lead wires.SpO2 Connection: In addition, the HP Viridia transmitter supports a SpO2 transducer connection. SpO2 can be measured continuously, intermittently at 1 or 5 minute intervals, or manually. Reusable sensors in adult finger, small adult/pediatric finger, and ear clip models can be used, as well as Oxisensor II™ disposable sensors. See Appendix B, “Accessories and Ordering Information” for a list of sensors.!Tel 4ECG Lead Set Connection Combiner ClipInfraRed Link to HP Palmtop PC and Wave ViewerBattery CompartmentTransmitter Label Radio Licence Label (not used in USA)Transmitter ButtonSpO2 Transducer ConnectionChest Diagram with LEADS OFF Lights

Transmitters1-8 Introduction to the HP Telemetry SystemChest Diagram & LEADS OFF Lights: The diagram on the front of the HP Viridia Transmitter shows standard lead placement for a 5-wire lead set. The white, black and red electrode positions represent standard AAMI 3-lead placement; the red, yellow and green electrode positions represent standard IEC 3-lead placement. Non-standard 3-wire lead placement diagrams are available at the HP Viridia Wave Viewer. Each electrode position has a light that illuminates if the corresponding electrode becomes unattached. In a LEADS OFF situation, this indicator will help you identify quickly which leads are off and re-attach them. If the reference lead is off, after you correct the situation you may find other lights illuminated as well. A second function of the Leads Off lights is to indicate successful power-up of the transmitter. When you insert a battery into the transmitter, all five lights should flash once. This indicates that the battery has adequate power for monitoring and that there is no transmitter malfunction. See “Inserting Batteries” on page 1-20 for details. The electrode lights are also used as an indicator that a manual SpO2 measurement has been initiated at the transmitter. HP Viridia Telemetry Battery ExtenderThe HP Viridia Telemetry Battery Extender (M2611A) enables operation of the HP Viridia transmitter with an external power source when a patient is not ambulating. The battery extender can be used with all HP Viridia transmitters shipped after December 1999, and any earlier transmitter that has been upgraded. (To identify an eligible transmitter, look for the opening at the base of the battery compartment.) The battery extender consists of a cradle, which is fitted over the battery compartment of the transmitter, and a cable connecting to a wall-mounted DC power module. When the battery extender is in use, no battery power is used (battery save mode). Note—The purpose of the battery extender is to conserve battery life; the extender does not recharge the battery.

Transmitters1-10 Introduction to the HP Telemetry SystemConnecting to the Battery ExtenderTo use an HP Viridia transmitter in battery-save mode, connect the transmitter to the battery extender in the following steps: Step Action1 Slip the cradle onto the base of the transmitter, aligning the extender prongs with the opening at the base of the transmitter. Press until you hear a click.Note—For accurate functioning, the battery cover must remain closed when the extender is in use. In addition, Hewlett-Packard recommends that the battery remain in the transmitter while the extender is in use.2 Connect the aqua connector between the cradle wire and the wall cable. Be sure the connection is secure; the yellow band of the connector should be completely covered. 3 Insert the power module into a wall power source.

TransmittersIntroduction to the HP Telemetry System 1-111 System IntroductionDisconnecting from the Battery ExtenderTo disconnect a transmitter from the battery extender for ambulatory monitoring, perform the following steps: Note—Removing the power module from the wall receptacle during monitoring causes the transmitter to reset and reboot before switching to battery power. During this brief interval, data from the transmitter is not available at the central station. This interruption does not occur if the cable is disconnected or if the transmitter is removed from the cradle. Step Action1 Disconnect the aqua connector between the cradle wire and the wall cable. Note—The connector is designed to come apart on its own if the patient gets up without disconnecting the connector.2 Tuck the loose end of the cradle wire into the pouch.

Transmitters1-12 Introduction to the HP Telemetry SystemHP M1400A/B Transmitter The HP M1400A/B telemetry transmitter acquires the patient’s ECG signal, amplifies and digitizes it, detects pace pulses, then sends it via an Ultra High Frequency (UHF) channel to a receiver in the receiver mainframe.Connecting/Disconnecting the Lead Set: The M1400A/B Transmitter supports 3, 4, or 5-lead sets. For safety, every lead should be secured to an electrode on the patient. To connect the lead set, push the lead block down firmly until it “locks.” LEAD SET CONNECTIONBATTERY COMPARTMENT (BACK)TRANSMITTER BUTTON

TransmittersIntroduction to the HP Telemetry System 1-131 System IntroductionTo disconnect the lead set, press in the tab on the lead block (as shown below) and pull the block up. Do not pull on the lead wires.Transmitter FeaturesTransmitterButton Both the HP Viridia Transmitter (see page 1-6) and the M1400A/B Transmitter (see page 1-12) have a transmitter button. Depending on how it is configured, pressing this button produces:• A “Nurse Call” message and tone• A “Nurse Call” message and tone, plus a delayed recording• A delayed recording• No response at the HP Viridia Information Center.Note—Delayed recordings generated by the transmitter button are stored in Alarm Review.If desired, you can turn the transmitter button off for individual patients at the HP Viridia Information Center by using the Telemetry Setup Window. See “Turning the Transmitter Button On/Off” on page 2-11 for additional information. On the HP Viridia transmitter, the transmitter button can also be used to initiate an SpO2 measurement. See “Making SpO2 Measurements” on page 4-6 for more information.(PLEASE DO NOTE PULL ON WIRES)PRESSPULL UP

Transmitters1-14 Introduction to the HP Telemetry SystemWaterResistance The Release B HP Viridia transmitter and the battery extender (except the power module) can withstand submersion in water for 5 minutes and exposure in a shower for 10 minutes. If the battery compartment gets wet, remove the battery and wipe the compartment dry before monitoring. See “Chapter 7. Telemetry System Cleaning” for details.CautionDisconnect the battery extender cradle from the power module prior to a patient’s showering.Earlier HP Viridia transmitters and the M1400A/B transmitters are also resistant to water. If either transmitter is exposed to liquids, remove the battery and dry the battery compartment thoroughly before monitoring.If the transmitter or battery extender needs cleaning, follow the instructions in “Cleaning the HP Viridia Transmitter & Battery Extender” on page 7-4 or “Cross-infection Prevention for the HP Viridia Transmitter & Battery Extender” on page 7-8.Pouch Use During normal use, the HP Viridia transmitter should be worn over clothing, in a pocket, or preferably in a pouch. WarningPlace the HP Viridia transmitter in a pouch or over clothing, or both, during patient use. The transmitter should not touch the patient’s skin during normal use.AutomaticShutoff A service feature of the HP Viridia Transmitter is RF Automatic Shutoff, which causes the transmitter to stop broadcasting a radio signal if there is no ECG signal for 10 minutes. This prevents interference with other transmitters in use. The INOP message at central is TRANSMITTER OFF. To restart monitoring, attached leads to the patient. Automatic Shutoff can be configured off. When configured off, batteries must be removed when the transmitters are not in use to prevent RF interference and unnecessary battery drain. The M1400A/B transmitters do not have the Automatic Shutoff feature.

TransmittersIntroduction to the HP Telemetry System 1-151 System IntroductionBattery Information The HP Viridia Transmitter and the M1400A/B Transmitter battery compartments are capable of accommodating any type of standard 9 volt battery. An 8.4 volt Zinc-Air battery can be used with the M1400A/B transmitter and ECG-only version of the HP Viridia transmitter. The transmitter was not designed for use with rechargable batteries.The battery compartment is located at the bottom of the HP Viridia Transmitter and the M1400A/B Transmitter. The length of time the battery lasts depends on:• The type of transmitter.• The battery.• The parameters being monitored - ECG only, ECG and continuous SpO2, or ECG and intermittent SpO2.When battery power is running low, the INOP message BATTERY WEAK appears in the patient sector to indicate the amount of battery life remaining:• HP Viridia transmitter - at least 15 minutes• M1400A/B transmitter - approximately 1 hourWhen there is no battery life remaining, the INOP message REPLACE BATTERY is displayed.Note—If the BATTERY WEAK message appears when you are making a STAT SpO2 measurement, or changing the SpO2 sample rate out of Manual, it may be necessary to replace the battery immediately in order to continue monitoring. Be careful not to short circuit the battery. Short circuiting is caused when a piece of metal touches both buttons (positive and negative terminals) at the top of the battery simultaneously (for example, carrying batteries in a pocket with loose change). More than a momentary short circuit will generally reduce the battery life.

Transmitters1-16 Introduction to the HP Telemetry SystemWarningCertain failure conditions, such as extended short circuiting, can cause a battery to overheat during normal use. High temperatures can cause burns to the patient and/or user, or cause the battery to flame. If the transmitter becomes hot to the touch, place it aside until it cools. Then remove the battery and discard it. It’s a good idea to place a piece of tape across the contacts of the battery to prevent inadvertent shorting. Have transmitter operation checked by service to identify the cause of overheating. The battery should be removed when the transmitter is stored. WarningBatteries should be removed from the transmitter at the end of the battery’s useful life to prevent leakage.WarningIf battery leakage should occur, use caution in removing the battery. Avoid contact with skin. Clean the battery compartment according to instructions in “Chapter 7. Telemetry System Cleaning”.Use of Zinc-AirBatteries Zinc-Air batteries can be used with ECG-only models of the HP Viridia transmitter, release A.01 and later, and with M1400A/B transmitters. A Zinc-Air battery cannot be used with an ECG/SpO2 transmitter. For maximum performance, observe the following guidelines:• Use Zinc-Air batteries within 1 year of manufacture.• Use Zinc-Air batteries within three months of opening the sealed package.• Store and use Zinc-Air batteries at near room temperature. They can lose 50% of their capacity at low temperatures (0oC /32oF and below). • Do not put Zinc-Air batteries in an environment with restricted air flow (for example, a plastic bag). Serious restriction of air flow can affect battery capacity. During normal use, the battery compartment provides adequate air flow.

TransmittersIntroduction to the HP Telemetry System 1-171 System Introduction• Zinc-Air batteries may take up to one minute to get to working voltage after they are removed from the airtight wrapper. You can hasten this by shaking the battery.MaximizingBattery Life By observing the following guidelines, you can optimize battery life in the HP Viridia transmitter: • REMOVE THE BATTERY (or turn it over/up-end it) when the transmitter is not in use.Note—Automatic Shutoff does not save battery life. In order to allow an automatic turn-on, the transmitter ECG and SpO2 functions are not completely disabled in this mode.•For SpO2 transmitters, when the SpO2 function is not in use, make sure the SpO2 sample rate is set to Manual. See “Changing the SpO2 Sample Rate” on page 6-9 for directions.• Be sure to press End STAT at the end of every STAT SpO2 measurement that is initiated at HP Wave Viewer and wait for the red sensor light to go out before removing the transducer.Disposal ofBatteries HP recommends that you remove the battery when the transmitter is not in use.CautionThe battery must be removed if a transmitter will be stored for an extended period of time. Important—When disposing of batteries, follow local laws for proper disposal. Dispose of batteries in approved containers. If local regulations require you to recycle batteries, recycle batteries in accordance with regulations.

When you place the battery in the compartment, set the base of the battery against the leaf spring, and press the terminal end down (as shown in the following illustration).Note—It may take about a minute for a Zinc-Air battery to get to working voltage after it is removed from its airtight wrapper. This start up can be hastened by shaking it.

Receiver ModuleIntroduction to the HP Telemetry System 1-231 System IntroductionReceiver ModuleThe HP receiver modules are housed in the receiver mainframe. Each receiver module is dedicated to a specific transmitter by an internal identity code. This prevents another patient’s waveform from being erroneously transmitted and displayed. The receiver acquires the ECG and SpO2 signals from the transmitter and sends them to the receiver mainframe. FRONT COVERRECEIVER MODULERECEIVER MAINFRAME

Receiver Mainframe1-24 Introduction to the HP Telemetry SystemReceiver MainframeThe HP receiver mainframe houses up to eight receiver modules. For each receiver, the receiver mainframe calculates the heart rate, and sends the waveform, alarms, inoperative messages (INOPS), and status messages over the HP Viridia monitoring network to the HP Viridia Information Center for display and recording. If SpO2 is available, the transmitter processes the data and sends it to the Viridia Information Center via the network as well.Turning theReceiverMainframe Onor OffThe receiver mainframe must be turned on for individual transmitters and receivers to work. To turn the receiver mainframe on, press the button on the lower left corner of the front of the mainframe. A green light illuminates to signify the mainframe and all the receivers are on.If the receiver mainframe is turned off, the light and all receiver modules are off.ReceiverMainframeMalfunctionLightA red light on the front panel of the mainframe illuminates when either the mainframe or one of the receivers has malfunctioned. Depending on the problem, you may see the message, NO DATA FROM BED, in single or multiple patient sectors. Contact your Hewlett-Packard Service Representative.When the mainframe is first turned on, the red light flashes. If no problems are detected, the flashing stops and the light turns off..PRESS POWER BUTTON TO TURN ONPRESS AGAIN TO TURN OFF

Antenna SystemIntroduction to the HP Telemetry System 1-251 System IntroductionChannelFrequencies The frequency of the HP Viridia transmitter and receiver are programmable, thus enabling changes in frequency if interference is detected. In case of interference, contact service.RetainingTelemetrySettingsIf power to the receiver mainframe is interrupted or turned off, settings controlled by the mainframe such as leads may be affected.• If the receiver mainframe is turned off for less than three hours, your settings should still be in effect.• If the mainframe is turned off for more than three hours, your settings revert to default, that is, to the configured settings at installation. Antenna SystemThe telemetry antenna system is custom designed for your unit to ensure adequate coverage, therefore the telemetry signal can only be received where there are receiving antennas. After it is received by the antenna system, it is sent to the receiver which recovers the patient's ECG and optional SpO2. This information is then sent to a monitoring display.

Turning Telemetry On/Off1-26 Introduction to the HP Telemetry SystemTurning Telemetry On/OffTelemetry monitoring can be turned on or off in one of several ways:• Automatically, if Auto Shutoff is enabled at the transmitter and if there is no ECG signal for 10 minutes. This situation creates a TRANSMITTER OFF inop at central. To restart monitoring, re-attach the lead wires.• Manually, by removing the transmitter battery. This action creates a NO SIGNAL inop at central. To restart, insert the battery.• Manually, by activating Monitoring Standby at the HP Viridia Information Center (click on Patient Window, then Standby). This action creates a MONITOR STANDBY message on the display. To restart monitoring, click on Resume Monitoring in the Patient Sector.

See “Making ECG Adjustments” on page 2-8.Step Action

Making ECG Adjustments2-8 ECG MonitoringMaking ECG AdjustmentsOverview You can make the following adjustments from the HP Viridia Information Center:• Change the lead or the lead label.• Change the wave size.• Swap leads (M1400A/B with 5-wire lead set only).With 4-(M1400A/B only) and 5-wire lead sets, you can monitor two leads. With a 3-wire lead set you can monitor one lead. When monitoring two leads, the first lead is the primary lead. Single lead arrhythmia analysis uses this lead. It is also the lead used for alarm and delayed recordings. Multilead analysis uses both leads. If you are not receiving a good ECG wave and the electrodes are securely attached, you should try changing the lead in which you are monitoring.Bandwidth Bandwidth is not user adjustable, but is assigned automatically by the information center. The settings are:Changing Lead/Label To change the lead/label place your cursor over the wave in the Patient Window and select the lead or label from the pop-up box to match the placement.Adjusting Wave Size To change the amplitude of the ECG wave on the display or for recordings, place your cursor over the wave in the Patient Window and select the size you want from the pop-up box.

Making Other Monitoring AdjustmentsECG Monitoring 2-11Introduction 2 ECG MonitoringMaking Other Monitoring AdjustmentsTurning the Transmitter Button On/OffOverview You can turn the Transmitter Button on the transmitter on or off by using the Telemetry Setup Window. Turning the Transmitter Button off inhibits Nurse Call alarms and/or recordings depending on how your system is set up.Task Summary Turn the Transmitter Button on the transmitter on or off by performing the following steps:Standby ModeOverview When a patient is temporarily off the unit or out of antenna range you can suspend monitoring by placing telemetry in Standby Mode. Standby suspends monitoring, and you won’t get any waveforms or alarms.If a patient leaves the unit without a transmitter, place telemetry in Standby. Note—If you remove the leads before putting a patient into Standby, you’ll get a LEADS OFF INOP, and reminders if configured. Step Action1 On the Patient Window click the All Controls button.1 On the All Controls Window click the Telemetry Setup button.1 On the Telemetry Setup Window turn the Transmitter Button on or off by clicking in the Transmitter Button Allow Calls checkbox. A check mark in the checkbox indicates that the transmitter button is on.

Making Other Monitoring Adjustments2-12 ECG MonitoringWarningIf you put telemetry in Standby Mode, you must remember to turn monitoring back on when the patient returns to the unit.If a patient leaves the unit while wearing a transmitter, there will be a NO SIGNAL INOP. You’ll need to silence the inop, and when the patient returns to the unit, telemetry monitoring will resume automatically. Standby mode is not needed in this case.Task Summary Place a patient in Standby by performing the following steps:Step Action1 On the Patient Window click the Standby button.2Select the patient’s location from the pre-defined list.3 Click the Suspend Monitoring button. This indefinitely suspends all monitoring and displays the following messages in the Patient Sector “No Data From Bed” and “Monitor Standby” and the location (for example, X-Ray). Note—Be sure to take the bed out of Standby before discharging. Since Standby is associated with the equipment assigned to a bed, if a patient is discharged and the bed is in Standby Mode, that equipment will be in Standby for the next patient, and monitoring will continue to be interrupted. 4 When the patient comes back, restart monitoring by clickinig on Resume Monitoring in the Patient Sector.

Optimizing System PerformanceECG Monitoring 2-13Introduction 2 ECG MonitoringTurning On/Off the Second ECG ChannelOverview If you have the M1400A/B Transmitter, you can turn the second ECG channel on or off by using the Telemetry Setup Window. Turning the second ECG channel off means that there will only be one ECG wave in Patient Sector, Patient Window, and for ST/AR analysis. When you turn the second ECG channel on delayed/alarm recordings have two 20-mm waves. When you turn the ECG channel 2 off, delayed/alarm recordings have one 40-mm wave. For a 3-wire lead set, the second ECG channel must be off, otherwise a continuous LEADS OFF message displays.Task Summary Turn the second ECG channel on or off by performing the following steps:Optimizing System PerformanceWhile telemetry monitoring offers many advantages, it can be a challenge. The reliability and quality of the signal transmission through the air and hospital walls is governed by a number of variables which can be difficult to control. A telemetry system cannot be as dependable as a hardwired bedside monitor that transmits its signal through a wire. The effect of interference on the telemetry system ranges from a momentary loss of ECG to complete inoperability, depending on the situation. The strength, frequency, and proximity of the source of interference to transmitters or the Step Action1 On the Patient Window click the All Controls button.2 On the All Controls Window click the Telemetry Setup button.3 On the Telemetry Setup Window turn the second channel on or off by clicking in the ECG Channel 2 checkbox. A check mark in the checkbox indicates that the channel is on.

Optimizing System Performance2-14 ECG Monitoringantenna system are factors that determine the degree of severity. In cases where the source of interference is known - for example, cellular phones, magnetic equipment such as MRI, other radio or motorized equipment - removing or moving away from the source of interference will increase the system’s dependability. WarningTelemetry should not be used for primary monitoring in applications where the momentary loss of the ECG is unacceptable. In this section, we’ll investigate some of the problems affecting ECG signal clarity and when possible, show you how you can greatly enhance performance.Note—The telemetry system also emits radio frequencies (defined in “System Specifications” on page 9-20) that may affect the operation of other devices. Contact the manufacturer of other equipment for possible susceptibility to these frequencies.The Telemetry SignalThe transmitter worn by the patient acquires the patient's physiological data, amplifies and digitizes it, detects pace pulses and broadcasts this information via radio waves to the antenna system. Since the signal passes through the air, it is susceptible to interference from many sources.Frequent Signal Strength and RF INOPSBecause the telemetry system is a wireless system, under certain conditions RF “dropouts” can occur. Dropouts result from a weak signal or RF interference. There will be signal drops to the bottom of channel for a minimum of 200 ms to indicate to the clinical user that it is a non-physiological event. If dropouts are frequent enough to affect the heart rate count, the TEL CANNOT ANALYZE INOP occurs. The following recording strip is an example of dropouts.If frequent dropouts are occurring, the following section describes some steps you can take to improve performance.

Optimizing System PerformanceECG Monitoring 2-15Introduction 2 ECG MonitoringSignalStrength The antenna system is custom designed for your unit, so reliable signal reception is only possible where there are receiving antennas. When the signal is too low, the following INOPS occur:• TEL CANNOT ANALYZE• WEAK SIGNAL• NO SIGNALTo correct, first check the location of the patient. If not in the coverage area, do one of the following.• Return the patient to the specified antenna coverage area.• Put telemetry in Standby Mode. See “Standby Mode” on page 2-11.WarningIf you put telemetry in Standby Mode, you must remember to turn monitoring back on when the patient returns to the unit. See “Standby Mode” on page 2-11.• If the patient is in the coverage area and is stationary, try moving the location of the transmitter or patient about six inches. RadioFrequencyInterferenceRadio frequency (RF) interference is caused by anything that intrudes into the transmitted electrical signal, such as paging transmitters and walkie-talkies. We are all familiar with electrical interference in our homes and cars when it causes “snow” on the television and static on the radio station. These same types of interference can occur with the transmitted telemetry signal. Even though the HP Telemetry System is designed to resist these effects, interference can occasionally be seen in the form of “dropouts”. To improve performance, the source of the interference must be identified and eliminated.Muscle andMovementArtifactMuscle and movement artifact differ from radio frequency interference since you can prevent much of the occurrence. Noise on the ECG signal can be caused by many sources, such as interference from other electrical equipment, muscle artifact and respiration variation. It is up to the clinician to use certain techniques to minimize these types of noise. Use the following table to help you troubleshoot the most common sources of ECG noise.

Overview4-2 SpO2 MonitoringOverviewThe SpO2 parameter measures the arterial oxygen saturation. That is, the percentage of oxygenated hemoglobin in relation to the total hemoglobin.If, for example, a total of 97% of the hemoglobin molecules in the red blood cells of the arterial blood combine with oxygen, then the blood has an oxygen saturation of 97%. The SpO2 numeric that appears on the monitor will read 97%. The SpO2 numeric indicates the percentage of hemoglobin molecules which have combined with oxygen molecules to form oxyhemoglobin.• The oxygen saturation is measured using the pulse oximetry method. This is a continuous, noninvasive method of measuring the arterial hemoglobin oxygen saturation. It measures how much light, sent from light sources on one side of the transducer, travels through patient tissue (such as a finger or an ear), to a receiver on the other side.• The amount of light getting through depends on many factors, most of which are constant, such as tissue or venous blood). However one of the factors, the blood flow in the arterioles, varies with time - because it is pulsatile.This measurement principle is used to derive the SpO2 measurement. The numeric that is displayed at the HP Viridia Information Center is the Oxygen saturation of the arterial blood - the measurement of light absorption during a pulsation.

OverviewSpO2 Monitoring 4-34 SpO2 MonitoringWarnings • When the specified NELLCOR® transducers are used, the application must be consistent with the manufacturer's own guidelines.• Prolonged, continuous monitoring may increase the risk of changes in skin characteristics, such as irritation, reddening, blistering or pressure necrosis, particularly on patients with impaired perfusion and varying or immature skin morphology. Specific attention must be given to sensor site inspection for changes in skin quality, proper optical path alignment and attachment. Check the application site at regular intervals and change the site if any compromise in skin quality should occur. More frequent checking may be required due to an individual patient's condition.• Setting the high SpO2 alarm limit to 100% is equivalent to switching off the high alarm limit. Therefore the upper alarm limit for oxygen saturation must be carefully selected in accordance with accepted clinical practices.• Pulse oximetry can overestimate the SpO2 value in the presence of Hb-CO, Met-Hb or dye dilution chemicals.Note—The SpO2 alarm delay built into the system is ten seconds. That means that the monitor generates an alarm if the averaged numeric value on the display stays beyond the alarm limit for more than 10 seconds.

Preparing for Telemetry SpO2 Monitoring4-4 SpO2 MonitoringPreparing for Telemetry SpO2 MonitoringOverview The HP Viridia Telemetry System provides remote monitoring of SpO2 measurement for adult and pediatric patients. You need to prepare your telemetry patient and perform setup tasks for the measurement to display at either the HP Viridia Information Center or at the HP Wave Viewer.Task Summary Perform the following steps to set up for telemetry SpO2 monitoring:Step Action1 Select the site and appropriate transducer (see “Selecting the Appropriate Transducer” on page 4-10).• Adult Finger - use for most adults. • Small Adult/Pediatric - use for small adults. • Ear Clip - use when neither hand has an appropriate site. 2 Attach the transducer cable to the transmitter.Plug reusable transducers directly into the transmitter.Plug disposable transducers into the adapter cable, then plug the adapter cable into the transmitter.

Preparing for Telemetry SpO2 MonitoringSpO2 Monitoring 4-54 SpO2 Monitoring3 Prepare the transducer (if disposable, remove the protective backing), and attach the transducer to the appropriate part of the patient’s body. Avoid sites with:•Decreased Arterial Flow, such as edematous tissue or distal to arterial catheters, intravenous catheters and blood pressure cuffs•Poor Skin Integrity, such as skin discoloration or nail polish.•Excessive MotionAdditionally, avoid:• Placing the sensor in an environment with bright lights. If necessary, cover the sensor with opaque material.• Use of excessive pressure at the application site, for example, transducer applied too tightly, excessive adhesive tape to secure the transducer, clothing or restraints that are too tight. These result in venous pulsations and inaccurate measurements, and may severely obstruct circulation.4 Use the pleth wave to check the signal quality at the patient’s side using the HP Wave Viewer (see “Checking SpO2 Signal Quality” on page 6-8.5 If necessary, change the SpO2 sample rate using the HP Wave Viewer (see “Changing the SpO2 Sample Rate” on page 6-9.)6 Adjust SpO2 alarms in the Patient Window.7 Make other adjustments in the Telemetry Setup Window.8 Inspect the site regularly to ensure skin integrity and correct optical alignment. Proper sensor placement is critical to accurate SpO2 monitoring.Step Action

Making SpO2 Measurements4-6 SpO2 MonitoringMaking SpO2 MeasurementsSpO2 measurements can be made automatically at pre-determined times, or manually on an as-needed basis.Automatic Measurements Automatic SpO2 measurements can be generated on a continuous basis, or intermittently at 1 or 5 minute intervals. Automatic measurement intervals are set at the HP Wave Viewer. Please see “Changing the SpO2 Sample Rate” on page 6-9 to set up the transmitter for automatic measurements. Manual Measurements Manual measurements can be initiated at the transmitter or at HP Wave Viewer. SpO2 must be turned on at central for alarms, and for display and trending. For measurements at the transmitter or HP Wave Viewer, the sample rate must be set to any choice except “Continuous”. To initiate an SpO2 measurement at HP Wave Viewer, see “Making a STAT SpO2” on page 6-10.Note—The HP Wave Viewer should not be connected to the transmitter when you are using the transmitter button to initiate an SpO2 measurement.Task Summary To initiate a manual SpO2 measurement at the transmitter, perform the following steps. Step Action1 Plug the transducer cable into the transmitter.2 Attach the transducer to the patient.3 Press and hold (~6 seconds) the Transmitter Button until the LA light begins flashing.

Measurement LimitationsSpO2 Monitoring 4-74 SpO2 MonitoringNote—When an SpO2 measurement is initiated, if the transmitter button is turned ON in the Patient Window, the transmitter button will also function according to its function defined during system configuration. For example, if the patient button is configured for Nurse Call/Record or Record, a recording will be generated when a manual SpO2 reading is initiated at the transmitter. The recording will include the last SpO2 reading, but not the current reading, which is still in process. Note—If the transmitter button is turned OFF in the Patient Window, a manual SpO2 measurement can still be made. Note—No measurement will be made if a Battery Weak condition exists. A measurement initiated before a Battery Weak INOP is displayed will be completed, but no further manual measurements can be made until the battery is replaced.Note—If a LEADS OFF condition occurs during a manual SpO2 measurement, the appropriate lead light will be lit upon completion of the measurement.Measurement LimitationsRefer to this section on problem situations if you have difficulty getting a signal or obtaining accurate measurements.DistortionAmbient light, motion, perfusion or incorrect sensor placement may affect the accuracy of the derived measurements. 4 When the transducer light turns off (~ 30 seconds later), the measurement value and time stamp will be displayed at central for up to one hour or until the next measurement is made, whichever comes first.5 Remove the transducer from the patient after the transducer light goes out.Step Action

Measurement Limitations4-8 SpO2 MonitoringArterial Blood FlowThe measurement depends on the pulsatile nature of blood flow in the arteries and arterioles; with the following conditions arterial blood flow may be reduced to a level at which accurate measurements cannot be made:•shock• hypothermia • use of vasoconstrictive drugs •anemiaWavelength AbsorptionThe measurement also depends on the absorption of particular light wavelengths by the oxyhemoglobin and reduced hemoglobin. If other substances are present which absorb the same wavelengths, they will cause a falsely high, or falsely low SpO2 value to be measured. For example:• carboxyhemoglobin • methemoglobin • methylene blue • indocyanine green*• indiocarmine**These chemicals are used in dye dilution cardiac output calculations.Ambient LightVery high levels of ambient light can also affect the measurement; an SpO2 INTERFERENCE message will appear on the display. The measurement quality can be improved by covering the transducer with suitable non see-through material.Note—If you are using NELLCOR® transducers, see the directions for use supplied with these transducers.For care and cleaning instructions, see “HP Reusable Transducers” on page 7-19.

SpO2 TransducersSpO2 Monitoring 4-94 SpO2 MonitoringSpO2 TransducersDisposable Transducers Only use disposable transducers once and then discard. However, you can relocate them to a different patient-site if the first location does not give the desired results. Do not reuse disposable transducers on different patients. Disposable transducers are not available as HP parts in the USA or Canada. Contact NELLCOR® Incorporated.Reusable Transducers You can use reusable transducers on different patients after cleaning and disinfecting them. See “HP Reusable Transducers” on page 7-19 for cleaning instructions. Reusable sensors should be changed to another site regularly. See Appendix B, “Accessories and Ordering Information” for ordering information.

Selecting the Appropriate Transducer4-10 SpO2 MonitoringSelecting the Appropriate TransducerThe following chart provides a guideline to select the most appropriate transducer for your patient. Select the most appropriate transducer by finding the patient’s weight on the vertical axis, and drawing a horizontal line across the chart. Each shaded area that the line passes through represents a transducer that you can use on this patient.Areas of dark shading indicate that the transducer is the most appropriate one in that weight range.Areas of light shading indicate that you can use the transducer in this weight range, even though it is not the most appropriate transducer.Greaterthan50 kg50403020151031D-20 D-25 M1192A100x140M1191A M1194APreferredTransducerAlternativeTransducerDisposable Transducers Reusable Transducers2.5ClipAdult FingerSmall Adult/Pediatric Finger

Applying the TransducerSpO2 Monitoring 4-114 SpO2 MonitoringApplying the Transducer Overview A minimum pulsatile flow must be present at the application site of your patient to obtain measurements. Select an appropriate transducer and apply the transducer properly to avoid incorrect measurements. Applying a small amount of pressure at the application site can improve the measurement. Use one of the preferred application sites for your transducer. Selecting the most suitable transducer and application site will help you to ensure that:• The light emitter and the photodetector are directly opposite each other and that all the light from the emitter passes through the patient's tissues,• The application site is of the correct thickness for light to pass through. If the application site is too thick or too thin, an SpO2 NON-PULSATILE INOP will occur. You should then select another site as appropriate.Positioning of the Light Emitters and PhotodetectorInspect the application site every 2 to 3 hours to ensure skin integrity and correct optical alignment. If skin integrity changes, move the transducer to another site.Light SourcePhotodetector

Applying the Transducer4-12 SpO2 MonitoringWarnings • Failure to apply the transducer properly may cause incorrect measurement of SpO2. • Specific attention must be given to sensor site inspection for changes in skin quality, proper optical path alignment and attachment. Check the application site at regular intervals and change the site if any compromise in skin quality should occur.• Using a transducer during MR imaging can cause severe burns. To minimize this risk, ensure that the cable is positioned so that no inductive loops are formed. If the transducer does not appear to be operating properly, remove it immediately from the patient.• Using a transducer in the presence of bright lights may result in inaccurate measurements. In such cases, cover the site with opaque material.• Injected dyes, such as methylene blue, or intravascular dyshemoglobins, such as methemoglobin, may lead to inaccurate measurements.• Performance may be compromised by excessive motion. This can lead to inaccurate SpO2 readings.• Avoid placing the SpO2 transducer on any extremity with an arterial catheter, or intravascular venous infusion line.• Do not use disposable transducers on patients who exhibit allergic reactions to the adhesive.

Applying the TransducerSpO2 Monitoring 4-134 SpO2 MonitoringAdult Finger Transducer (M1191A) Push the transducer over the fingertip in such a way that the fingertip touches but does not protrude from the end of the transducer. The fingernail must be uppermost and the cable must lie on the back of the hand. This ensures that the light sources cover the base of the fingernail giving the best measurement results. The cable can be held in place by the accompanying wristband.WarningFailure to apply the transducer properly may cause incorrect measurement of SpO2. For example, not pushing the transducer far enough over the finger can result in inaccurate SpO2 readings. Pushing the transducer too far, so that the finger protrudes from the transducer, can pinch the finger, resulting in inaccurately low SpO2 readings.

Applying the Transducer4-14 SpO2 MonitoringSmall Adult/Pediatric Finger Transducer (M1192A)Push the transducer over the fingertip in such a way that the fingertip touches but does not protrude from the end of the transducer.WarningFailure to apply the transducer properly may reduce the accuracy of the SpO2 measurement.

Applying the TransducerSpO2 Monitoring 4-154 SpO2 MonitoringEar Clip Transducer (M1194A) Clip the probe onto the fleshy part of the ear lobe as shown in the diagram below. The plastic fixing mechanism helps to minimize artifact generated by patient motion. Do not position the probe on cartilage or where it presses against the head.The clip transducer can be used as an alternative if the adult finger transducer does not provide satisfactory results. The preferred application site is the ear lobe, although other application sites with higher perfusion (such as the nostril) can be used. Due to the physiologically lower perfusion in the ear lobe, you should be aware of the reduced accuracy of the measurement and more frequent INOPs.WarningFailure to apply the clip transducer properly may reduce the accuracy of the SpO2 measurement. Disposable Transducers See the Directions for Use supplied by NELLCOR® Incorporated for instructions on preparation and application of disposable transducers.WarningWhen the specified NELLCOR® transducers are used, the application must be consistent with the manufacturer's own guidelines.

Optimizing Transducer Performance4-16 SpO2 MonitoringOptimizing Transducer PerformanceTo get the best results from your SpO2 reusable transducer:• Always handle the transducer and cable with care. The soft finger sleeve houses a sensitive electronic device that can be damaged by harsh treatment. Always protect the cable from sharp-edged objects.• Use the wristband that is supplied with your M1191A transducer. By keeping the cable between the finger transducer and the wristband fairly loose, you will maintain good monitoring conditions. Normal wear and tear associated with patient movement and regular transducer cleaning naturally mean that your transducer will have a limited lifetime. However, provided you handle the transducer and its cable with care, you can expect useful service from it for up to two years. Harsh treatment will drastically reduce the lifetime of the transducer. Moreover, HP's warranty agreement shall not apply to defects arising from improper use.

Turning the SpO2 Parameter On/OffSpO2 Monitoring 4-174 SpO2 MonitoringTurning the SpO2 Parameter On/Off Overview The SpO2 parameter is turned on or off at the HP Viridia Information Center by using the Telemetry Setup Window. Turning the SpO2 parameter off at the Information Center also turns off:•SpO2 alarms•SpO2 display of numerics•SpO2 trending.After you turn SpO2 on, you should adjust the sample rate to match your patient’s acuity by using the Wave Viewer. After you turn SpO2 off, setting the sample rate to Manual using the Wave Viewer will help you conserve the transmitter’s battery life. Task Summary Turn the SpO2 parameter on or off by performing the following steps:Step Action1 On the Patient Window click the All Controls button.2 On the All Controls Window click the Telemetry Setup button.3 On the Telemetry Setup Window, turn SpO2 parameter on or off by clicking in the Parameter ON checkbox.

SpO2 Alarm and INOP SummarySpO2 Monitoring 4-194 SpO2 MonitoringSpO2 Alarm and INOP SummarySpO2 alarms are latching or non-latching, depending on the release of the HP Viridia Receiver Mainframe. For release D.02 and above mainframes, SpO2 alarms are non-latching. That is, when an SpO2 limit is exceeded, if the alarm is not silenced, it will reset automatically if the patient’s alarm condition returns within the limits. This reduces the number of times you will need to reset alarms at the information center when an alarm condition has been corrected at the patient’s side (for example, movement-induced artifact alarms). In the D.01 release of the HP Viridia Receiver Mainframe, SpO2 alarms are latching - meaning that they must be silenced by a clinician. Silencing an alarm manually is the only way to reset the alarm indicators (sound, message, and highlighting in the patient sector). To find out which release HP Viridia Receiver Mainframe your unit uses, see your service department.The following table lists the SpO2 alarms and the description of the conditions required to generate these alarms.Message Level Sound Description**SpO2 > upper limit Yellow Continuous SpO2 value greater than the upper SpO2 measurement limit.Important—Setting the high SpO2 alarm limit to 100% is equivalent to switching off the high alarm.**SpO2 < low limit Yellow Continuous SpO2 value less than the lower SpO2 measurement limit.

Battery Information5-14 HP Viridia Wave Viewer BasicsBattery Status The HP Wave Viewer software monitors the palmtop battery voltage and informs you of the need to replace the batteries via a screen message. You can also use the battery monitor in the “setup” program within the palmtop System Manager to predict the remaining battery capacity. When the indicator falls below the 1/4 level, fresh alkaline batteries should be installed.Additionally, the palmtop has a self test ( ) that includes reading the battery voltage. This self test procedure necessitates rebooting of the palmtop.When to Replace Palmtop BatteriesWhen you see a low-battery message in the display, replace the indicated batteries as soon as possible. If the palmtop beeps and turns off immediately after you turn it on, replace the main batteries.The backup battery, which prevents data loss when the main batteries are dead or out of the unit, should be changed a year after it is installed even if a low backup-battery message doesn’t appear.Removing and Installing Palmtop BatteriesCautionDo not remove the main batteries if the backup battery is dead--complete memory loss will result. Replace the backup battery first in this case.WarningDo not mutilate, puncture, or dispose of batteries in fire. The batteries can burst or explode, releasing hazardous chemicals. Replace batteries with only the types recommended in this manual. Discard used batteries according to the manufacturer’s instructions. The back-up (lithium) battery can explode if it is inserted incorrectly.ESC ON

Electromagnetic CompatibilitySystem Safety and Specifications 9-3Introduction9 Safety/SpecificationsElectromagnetic CompatibilityThe electromagnetic compatibility (EMC) validation of the HP Telemetry System (comprising the HP M2600A Viridia Telemetry System and/or the HP M1403A Digital UHF Telemetry System with Option C03) included testing performed according to the international standard for EMC with medical devices. See the Manufacturer’s Declaration for details.HP M2600A Viridia Telemetry System Testing During the test program the M2600A was subjected to many EMC tests, both international standard and HP proprietary tests. During most of the testing no anomalies were observed. For three of the tests, EN 61000-4-3 Radiated Immunity, IEC 801-4 Fast Transients, and IEC 801-2 Electrostatic Discharge, some reduced performance was observed.EN61000-4-3 EN61000-4-3 specifies that the product be subjected to a field of 3 V/m over a frequency range of 26 to 1000 MHz with no degradation of performance. At most of the test frequencies over the specified range, no anomalies were observed. However at the transmit/receive frequencies, and a few others, the radiated field caused interference with a resulting drop-out of signal. For these test points the radiated field was reduced to the level at which communication was restored. These reduced levels are shown in the following table.Table 4: Minimum Immunity Level (V/m)In Band Radiation(Transmit freq. +/- 1 MHz) Out of Band RadiationTransmitter 0.03 1.81 (380 MHz - 400 MHz)2.83 (at 571 MHz)Receiver 0.01 Pass at 3 V/m

Electromagnetic Compatibility9-4 System Safety and SpecificationsIEC 801-4 IEC 801-4 specifies that the product be subjected to high speed pulses up to 1000 V applied to the power cord and 500 V applied to all I/O cables greater than 3 m. During all of this testing no anomalies were observed on the central station display. However at pulse levels of 300 V and above applied to the power cord, occasional spikes appeared on the monitor connected to the analog output of the receiver mainframe. These spikes sometimes caused the heart rate reading (on the analog output monitor only) to change momentarily.HP M1403A Digital UHF Telemetry System with Option C03 TestingDuring the test program, the M1403A with Option C03 was subjected to many (EMC) tests, both international standard and HP proprietary tests. During most of the testing, no anomalies were observed. For two of the tests, IEC 801-3 Radiated Immunity and IEC 801-4 Fast Transient/Burst Immunity, some reduced performance was observed.IEC 801-3 IEC 801-3 specifies that the product be subjected to a field of 3 V/m over a frequency range of 26 to 1000 MHz with no degradation of performance. At many of the test frequencies over the specified range, no anomalies were observed. At +/- 10 MHz of the transmitter operating frequency, radiated levels were reduced to 0.01 V/m to avoid M1402A receiver channel dropout.During radiated immunity testing of the M1400B transmitter, there were some test points where increased width of the ECG trace was observed. For those test points, the radiated field was reduced to the level at which the ECG trace returned to normal. The reduced passing levels for the M1400B transmitter are as follows:• 0.382 to 1.5 V/m from 80 MHz to 140 MHz• 0.439 to 2.9 V/m from 300 MHz to 610 MHzIEC 801-4 IEC 801-4 specifies that the product be subjected to high speed pulses up to 1000 V to the power cord and 500 V to all I/O cables greater than 3 m. During and after most of the test pulses, no anomalies were observed. However, at pulse levels above 300 V applied to the power cord, spurious pulses were observed. There was no degradation of performance when 500 V was applied to the input/output cables.

Electromagnetic CompatibilitySystem Safety and Specifications 9-5Introduction9 Safety/SpecificationsHP Telemetry System CharacteristicsThe phenomena discussed above are not unique to the M2600A or M1403A with Option C03, but are characteristic of wireless patient monitors in use today. This performance is due to the very sensitive high gain front end amplifiers used to display the physiological signals and the nature of wireless communication. Among the many similarly performing monitors already in use by customers, interference from electromagnetic sources is rarely a problem.Avoiding EMIWhen electromagnetic interference (EMI) is encountered, there are a number of things that can be done to mitigate the situation.• Eliminate the source. Possible sources of EMI can be turned off or moved away to reduce their strength.• Attenuate the coupling. If the coupling path is through the patient leads, the interference may be reduced by moving and/or rearranging the leads. If the coupling is through the power cord, connecting the M2600A or M1403A with Option C03 to a different circuit may help.• Reduce the sensitivity of the system. In all of the EMC testing, the M2600A and M1403A were adjusted to maximum sensitivity. For the ECG amplifier the gain was four times what is normally required. By reducing the gain of the system receiving the EMI, the interference can often be eliminated. • Add external attenuators. If EMI becomes an unusually difficult problem, external devices such as an isolation transformer or a transient suppressor may be of help. An HP Customer Engineer can be of help in determining the need for external devices.

Enhancement DetailsSystem Releases C-5Introduction C System ReleasesLatching/Non-latching SpO2 AlarmsThis enhancement reduces the number of times you need to reset alarms at the central station when a condition such as movement-induced artifact has already been corrected at the patient’s side. With Release D.02 HP Viridia receiver mainframes, SpO2 alarms are non-latching; that is, an active SpO2 alarm or inop automatically resets when the patient’s condition returns within limits or the inop is corrected, without silencing the alarm.This change affects SpO2 alarms in all modes - continuous, intermittent, and manual. Note—Other telemetry alarms behave differently. For example, ECG telemetry alarms are considered as arrhythmia alarms at the HP Viridia Information Center. Telemetry ST alarms are non-latching.In the D.01 and earlier releases of the HP Viridia Receiver Mainframe, SpO2 alarms are latching - meaning that they must be silenced by a clinician. With latching alarms, silencing an alarm manually is the only way to reset the alarm indicators (sound, message, and highlighting in patient sector). See also “Alarm Management and Setup: Silencing Alarms” in HP Viridia Information Center User Guide.
