Note:
The information in this section is only applicable for Wireless Medical
Telemetry Service (WMTS).
About Transceivers
Wireless 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 transceivers 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 bedside 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 Transceivers
Before a transceiver can be used with the PatientNet System, it must first be programmed with a Network Number and Monitor I.D. number to match the corresponding 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) connector, 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 currents 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 administrator.

Impedance Values
The 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 Notes
Before operating the WMTS transceivers, read and follow all warnings and cautions
presented in this section.
Warnings
1. Do not use the output of the DT-4500 as a synchronization source for cardiac 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 cardiac 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 connector 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 accessory 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.

Procedure Alarm Silence (PAS) Button
Depressing the PAS button, while the PAS Status Indicator LED is flashing, informs
the clinicians at the Central Station area that the attending nurse will be performing a
procedure to the patient that may cause inadvertent false alarms at the Central Station
(i.e. changing lead wires, electrodes, etc.)
Once the PAS button is pressed, the following events occur at the Central Station.
1. A timer is displayed in the fourth patient block configurable field that displays
the length of Procedure Alarm Silence time remaining on the transceiver.
CAUTION: All non-level one alarms are ignored while the PAS alarm is active.
2. “PA SILENCE” is denoted in Full Disclosure for the duration of the PAS
period.
Once the PAS button is pressed, the DT-4500 enters the PAS Mode with the following
indications:
1. The active time is set for 120 seconds and begins counting down.
2. The active time is transmitted to the Central Station.
3. The PAS Status LED indicates the time remaining through its flash speed. The
LED flash speed increases as the PAS time remaining decreases from 120 seconds to 0 seconds.
4. The attendant can reset the PAS active time to 120 seconds by pressing both
Attendant Present buttons again.
The Procedure Alarm Silence alarm remains active until one of the following conditions occur:
1. The transceiver no longer sends the procedure alarm silence indicator to the
Central Station.
2. A level one alarm is detected and triggered at the Central Station
3. The patient tile alarm text area is clicked on. All alarms are set to ON once
this area is clicked.

Upon Power-On, all LED indicators are illuminated for a brief period. After the specified time period, only those LEDs displaying positive (or negative) transceiver functions, as described in each section below, remain illuminated.
Procedure Alarm Silence Status Indicator
The Procedure Alarm Silence Status Indicator is illuminated when the PAS function is
active. The LED flashes while the Procedure Alarm Silence button is unlocked or the
PAS active time is running low. The PAS button can only be pressed and activated
during this unlocked phase. Refer to the section on “Procedure Alarm Silence (PAS)
Button” on page 189 for more information.
External Serial Devices (I/O)
The External Serial Device (I/O) LED is illuminated when an external serial device is
connected, detected and maintaining a logical communication link.
Note:
When illuminated, be sure that the device is not connected to the patient.
Low Battery (BATT)
The Low Battery (BATT) LED is illuminated while the battery voltage remains good;
however, the LED flashes when the battery voltage falls below a predetermined value.
When the battery power falls below a predetermined value, then the transceiver will
automatically power itself off.
RF link (RF)
The RF link indicator is illuminated while there is RF communication between the
DT-4500 transceiver and the Central Station. The LED flashes if there is communication between the DT-4500 transceiver and the Access point, but not the Central Station.
Electrode Status Indicators (RA, LA, RL, LL, V1)
Each ECG electrode wire is named, color coded (Table 21), and represented by an

2. Use a cloth moistened with distilled water to rinse away the cleaning solution.
3. Dry thoroughly with a lint-free cloth.
Disinfecting
Use 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.
Sterilization
Leadsets may be sterilized by EtO, when indicated. Use the hospital-approved procedure 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 Maintenance
Transceiver Storage
Store the transceiver with the leadset attached and hanging freely. If that is not possible, 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 Transceiver
To 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 Antenna
The 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 TRANSCEIVERS
Installing and Removing a Battery
See “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 orientation 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.
Warnings
1. ECG lead wires must be dressed and secured to the patient to prevent the
possibility of them encircling the patient’s neck and causing strangulation.
2. When installing or replacing the battery, visually inspect the battery
compartment and ensure that there are no foreign objects inside. A conductive 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, disassemble, or dispose of batteries in fire.
Cautions
1. 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 worn
2. 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.

CAUTION: All non-level one alarms are ignored while the PAS alarm is active.
2. “PA SILENCE” is denoted in Full Disclosure for the duration of the PAS
period.
Once the PAS button is pressed, the DT-7000/7001 enters the PAS Mode with the following indications:
1. The active time is set for 120 seconds and begins counting down.
2. The active time is transmitted to the Central Station.
3. The PAS Status LED indicates the time remaining through its flash speed. The
LED flash speed increases as the PAS time remaining decreases from 120 seconds to 0 seconds.
4. The attendant can reset the PAS active time to 120 seconds by pressing both
Attendant Present buttons again.
The Procedure Alarm Silence remains active until one of the following conditions
occur:
1. The transceiver no longer sends the procedure alarm silence indicator to the
Central Station.
2. A level one alarm is detected and triggered at the Central Station
3. The patient tile alarm text area is clicked on. All alarms are set to ON once
this area is clicked.
4. The attendant presses the PAS button while PAS is active. This will automatically cancel the 120 second PAS at the Central Station, and will re-enable the
audible alarm tone.

LED Indicators Function
Once the transceivers exit Standby Mode, either by pressing the Attendant Present or
Power buttons, all LED indicators are illuminated for a brief period. After the specified time period, only those LEDs displaying positive (or negative) transceiver functions, as described in each section below, remain illuminated.
Procedure Alarm Silence Status Indicator
The Procedure Alarm Silence Status Indicator is illuminated when the PAS function is
active. The LED flashes while the Procedure Alarm Silence button is unlocked or the
PAS active time is running low. The PAS button can only be pressed and activated
during this unlocked phase. Refer to the section on “Procedure Alarm Silence (PAS)
Button” on page 189 for more information.
External Serial Devices (I/O)
The External Serial Device (I/O) LEDs are labeled 1-4 and are each illuminated when
there is an external serial device connected, detected, and maintaining a logical communication link to the corresponding I/O data port (fig. 92).
Low Battery (BATT)
Note:
The Low Battery LED is only functional on the DT-7001.
The Low Battery (BATT) LED is illuminated while the battery voltage remains good;
however, the LED flashes when the battery voltage falls below a predetermined value.
When the battery power falls below a predetermined value, then the transceiver will
automatically power itself off.
RF Link (RF)
The RF link indicator is illuminated while there is RF communication between the
DT-7000 and DT-7001 transceivers and the Central Station. The LED flashes if there
is communication between the transceivers and the Access point, but not the Central
Station.
Power Adapter
The Power Adapter LED is illuminated when the transceiver is powered from an
external power source that is connected to the Power Connector (fig. 92), and not one
of the I/O ports.

Cleaning
This section provides cleaning and maintenance instructions for DT-7000 and DT7001 transceivers.
Read and follow all precautions when cleaning transceivers.
WARNING: No claims are made concerning the sterility of the DT-7000 and DT-7001
Instrument Transceivers.
CAUTION: Do not sterilize any part of the transceivers. Gas sterilization, autoclaving, liquid immersion, and other sterilization methods can cause serious damage to
the devices that may not be obvious to the user.
Note: DO NOT use abrasive cleaners.
Cleaning the Chassis
1. Transceivers can be cleaned with a gauze pad or cloth moistened with one of
the following agents:.
• Soap and Water
• Quaternary Ammonium
• Glutaraldehyde 2%
• Dilute Chlorine Bleach (sodium hypochlorite), 10% solution, freshly made
in past 24 hours
• Isopropyl Alcohol 70%
• Ethyl Alcohol
2. Use a cloth moistened with distilled water to rinse away the cleaning solution.
3. Dry thoroughly with a lint-free cloth.

Use and Maintenance
Connecting to the Bedside Monitor
See Figure 92 on page 200 for an image of the DT-7000/DT-7001 controls and LED
indicators.
Note:
Before the transceiver is connected to the bedside monitor, the system
administrator must program it with the bedside device specific software
module.
1. Attach the transceiver to the bedside monitor by sliding the Device Hook over
the Mounting Disk until the transceiver snaps into place. The Mounting Disk
is provided with the transceiver and is attached to the bedside device through
adhesive or hardware tools.
2. Connect the AC power adapter into the power port located on the bottom of
the transceiver.
3. Plug the AC power adapter into the wall electrical outlet. If the AC power
adapter is not used, the transceiver will operate either from its internal battery
(DT-7001 models) or, on some bedsides, from connection to the bedside
device.
4. Attach the host end of the I/O cable to I/O port 1 (Ports 2, 3 and 4 will be
functional in future releases).
5. Attach the other end of the I/O cable to the bedside monitor.
