INTRODUCTION
System Overview
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 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 paper pouch, and used with a 6-wire
leadset connected to the electrodes on the patient.
The DT-7000 and 7001 are the PatientNet bedside-device transceivers and are physi-
cally connected to bedside monitors (other manufacturers’ bedside monitors and ven-
tilators).
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.
Equipment Site Selection/Location
The DT-7000 transceiver is attached to a bedside device through the use of the adhe-
sive strip or screws.

Clinical Use and Responsibility
CAUTION: United States Federal law restricts this device to sale by, or on the order of, a
physician or properly licensed practitioner.
The PatientNet System provides the technology to monitor cardiac rhythms, vital
signs, and equipment alarms for patients with various levels of acuity in multiple
patient care settings.
The monitoring system does not replace physicians, caregivers or system operators.
We recognize that machines are not capable of replacing human judgment, and
emphasizes the importance of the human element in the determination of any patient
care interventions.
Implementation of clearly documented and communicated patient care guidelines and
protocols accepted by the healthcare team is essential to the optimal use of the
PatientNet System.
The following list is intended to provide guidance in determining potential high risk
patients, but the actual definition for risk is a clinical judgment reserved for the care-
givers.
• clinically unstable patients
• patients who require frequent intervention
• patients with pacemakers
• patients with a history of rapid or frequent rate and/or rhythm changes
• patients who experience dramatic changes in their QRS complexes
• patients receiving medications that could result in rapid or frequent rate and/
or rhythm changes
• ventilator-dependent patients

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 Procedural 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 condi-
tions 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 automati-
cally 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 speci-
fied time period, only those LEDs displaying positive (or negative) transceiver func-
tions, 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 Key is unlocked or the
PAS active time is running low. The PAS key can only be pressed and activated dur-
ing this unlocked phase. Refer to the section on “Procedure Alarm Silence (PAS) But-
ton” on page 14 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 com-
munication link to the corresponding I/O data port (fig. 1).
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-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. 1), and not one
of the I/O ports.
