WMTS TRANSCEIVERSPatientNet Operator’s Manual, v1.04, 10001001-003, Revision B 183All information contained herein is subject to the rights and restrictions on the title page.WMTS TRANSCEIVERSNote: The information in this section is only applicable for Wireless Medical Telemetry Service (WMTS).About TransceiversWireless Medical Telemetry Services (WMTS) Remote Transceivers provide the link between the patient and the Central Station through the newly approved 608 - 614 MHz Medical Telemetry frequency band. The ambulatory and bedside device trans-ceivers communicate data to the Central Station through the Access Point transceiver. In addition, the transceivers are capable of receiving control commands for self-use or connection transfer. The PatientNet ambulatory transceiver is the DT-4500. This transceiver is worn by the patient and usually carried in a gown pocket or pouch, and used with a 3, 4, or 5-wire leadset connected to the electrodes on the patient. The DT-4500 is IPX7 compliant, so it can be submerged in 1m of water for up to 30 minutes.The DT-7000 and DT-7001 are the PatientNet bedside-device transceivers and are physically connected to bedside monitors (other manufacturers’ bedside monitors and NPB 7200 series ventilator).The DR-10000 Access Point transceiver collects data from the ambulatory and bed-side transceivers, sends that data to the Central Station, and transmits control data to the transceiver devices.WARNING: Remove transceivers from patients before MRI and CAT scan procedures, and store the transceivers outside the room where such equipment is located. Close proximity to MRI or CAT scan equipment may result in damage to transceivers.Programming TransceiversBefore a transceiver can be used with the PatientNet System, it must first be pro-grammed with a Network Number and Monitor I.D. number to match the correspond-ing Central Station. Consult your facility’s system administrator to perform these functions.WARNING: When programming the DT-4500 through the External Serial Device (I/O) con-nector, it must be disconnected from the patient. The accessory connector shall be kept covered when not in use with the supplied protective cover. Failure to follow these instructions could lead to excessive voltages and cur-rents being applied to the patient, resulting in cardiac arrest.The corresponding Central Station must also be programmed to this Network Number and Monitor Identification number.If you have any questions about the programming status, contact your system adminis-trator.

WMTS TRANSCEIVERSPatientNet Operator’s Manual, v1.04, 10001001-003, Revision B 185All information contained herein is subject to the rights and restrictions on the title page.Impedance ValuesThe DT-4500 Ambulatory Transceivers electrode impedance values, which are displayed on the OpenNet Transceiver Status screen, indicate the quality of the signal connection and are not the actual impedance values that are measured by the system. The electrode impedance values range from 100 to 200 (optimal). The typical values range between 180 and 200.If the electrode’s impedance value is greater than the defined Quality Threshold value, then its LED is illuminated. The DT-4500 stores the Quality Threshold value and uses this value to determine whether or not the electrode LED should be illuminated when the Attendant Present buttons are pressed. See Figure 91 on page 190 for details on the DT-4500 Buttons and LED indicators. Note: A Lead Off alarm will occur when an electrode’s impedance value drops to 150 (150 is the default Loose Lead Threshold value).User Warnings, Cautions, and NotesBefore operating the WMTS transceivers, read and follow all warnings and cautions presented in this section.Warnings1. Do not use the output of the DT-4500 as a synchronization source for car-diac defibrillation. Delays in presentation of the R-Wave may be as much as 40 milliseconds.2. Do not monitor pacer patients with a 3 wire leadset when reliable pacer detection is required. Pacer pulse detection can be erratic when only a single vector is monitored. Always use a 5 wire leadset when reliable pacer detection is required.3. The DT-4500 is a type BF patient applied device. It is not suitable for direct cardiac application, for use in the operating room, or during car-diac surgery. Use in these environments could cause hazardous voltages and currents being applied to the patient’s heart, resulting in cardiac arrest.4. Only authorized type BF devices can be plugged into the accessory con-nector of the DT-4500 when it is applied to the patient. The accessory connector must be kept covered when not in use with the supplied acces-sory connector cover. Failure to follow these instructions could lead to hazardous voltages and currents being applied to the patient resulting in cardiac arrest.5. Total submersion of the patient worn transceiver and/or patient leadset/antenna may severely limit its transmission range causing loss of patient monitoring. When subjecting the patient and transceiver to submersion, he/she should be carefully monitored to ensure that there is no signal loss.6. Use only VitalCom Power Supply Part Number 395005 with the DT-7000/DT-7001.

WMTS TRANSCEIVERSPatientNet Operator’s Manual, v1.04, 10001001-003, Revision B 195All information contained herein is subject to the rights and restrictions on the title page.Cleaning1. Wipe the leadset with a solution of soap and water.2. Use a cloth moistened with distilled water to rinse away the cleaning solution.3. Dry thoroughly with a lint-free cloth.DisinfectingUse hospital-approved disinfecting procedures such as those recommended by AAMI or AORN. 1. Wipe the leadset with a fresh 10% solution of chlorine bleach and water or a 2% gluteraldehyde solution such as Cidex. 2. Use a cloth moistened with distilled water to rinse away the cleaning solution.3. Dry thoroughly with a lint-free cloth.SterilizationLeadsets may be sterilized by EtO, when indicated. Use the hospital-approved proce-dure for EtO sterilization, such as those recommended by AAMI. The Leadsets are designed to remain effective after up to 10 exposures to EtO sterilization Cycles.Use and MaintenanceTransceiver StorageStore the transceiver with the leadset attached and hanging freely. If that is not possi-ble, then wrap the leadset loosely around the transceiver. Wrapping the leadset tightly around the transceiver can damage the wires.Note: The DT-4500 Ambulatory Transceiver contains no user-serviceable parts. Thus, maintenance service is not needed.Attaching and Removing a Leadset from the TransceiverTo attach, carefully grasp the leadset connector cover, holding it with the small knob facing upward, and push the leadset into the ECG lead wire connector. Make sure that the leadset is completely inserted into the connector and is flush with the DT-4500 chassis.To remove the leadset, grasp hold of the sides of the leadset connector cover and pull straight out. If the leadset is difficult to remove, then you can slightly move the leadset cover side-to-side until it is released.Internal AntennaThe DT-4500 transmits in the 608-614 MHz frequency range. The omnidirectional antenna is a part of the leadset system, with each lead wire paired with an antenna wire. Transceiver output power and system operation requirements are defined by the FCC. Therefore, it is essential that the leadset provided not be modified or altered in any way.
WMTS TRANSCEIVERS196 PatientNet Operator’s Manual, v1.04, 10001001-003, Revision BAll information contained herein is subject to the rights and restrictions on the title page.Installing and Removing a BatterySee “Specifications” on page 247 for acceptable batteries.Note: Battery service life can be substantially improved by using nine-volt lithium batteries.To install a 9V transceiver battery, first open the transceiver battery compartment by placing your thumb and forefinger on the compartment latch and flipping it open. Inspect the battery compartment and insure that there is no foreign object present that could block the battery contact or short the battery terminals. Next, place a 9V battery inside the compartment with the prongs touching the compartment contacts. The ori-entation of the battery prongs against the contacts does not matter, so long as the prongs and contacts are touching. Finally, close the battery compartment door by pressing it until the latch clicks into place and the compartment is secure.To remove a battery, simply follow the installation steps listed above and discard the used battery per applicable regulations.Warnings1. ECG lead wires must be dressed and secured to the patient to prevent the possibility of them encircling the patient’s neck and causing strangula-tion.2. When installing or replacing the battery, visually inspect the battery compartment and ensure that there are no foreign objects inside. A con-ductive object making contact with the battery contacts could cause the battery and battery compartment to overheat, resulting in burns to the patient and to the attendant removing the battery.3. A foreign object blocking battery contact with the DT-4500 could prevent its operation resulting in failure to monitor the patient.4. Always perform a battery check procedure after installing or replacing the battery.5. Lithium Batteries may explode if mistreated. DO NOT recharge, disas-semble, or dispose of batteries in fire.Cautions1. Transceivers should be carried securely in pouches or in a pocket of a patient’s gown. If the weight of the transceiver pulls on the wires, then the wires can be damaged or worn2. Make sure that the wires are not twisted around each other; since, this can interfere with transmission and produce noise.3. Make sure that the lead wires are not inadvertently pinched in the bed rails. This may cut the insulation or break the leadset.
