Patient-Worn Transmitters (90341, 90347, 90343, 91341, 91343, 91347)
The patient-worn transmitter is a small, battery-powered device that
collects physiologic data and communicates it via radio frequencies
(RF) through a system of ceiling-mounted antennas to a receiver
and central monitoring station for viewing and analysis. The
transmitter must be in range of a receiver module or its ceilingmounted antenna system for surveillance monitors to display
waveforms and generate alarm events and patient data (trends).
Spacelabs offers several patient-worn transmitter models that vary
in frequency-operation and clinical functionality, described in Table
1-1 and in Table 1-2 on page 1-7.

Selecting Options for the 90341/91341/91347 Lead Display
There are two operational modes available with the 90341 dual-lead
transmitter: (1) the standard mode which offers a choice of one V
lead (V1-6), plus lead II, or (2) the limb lead mode which offers
choices of the leads I, II, III, AVR, AVL, or AVF. The standard mode is
available if the chest lead is applied. The limb lead mode is available
when there is not a chest lead applied. Loss of the chest electrode
changes the ECG - LEAD SELECT menu to the limb lead mode if the
left arm, left leg, and right arm electrodes are intact.
Note:
Both modes work correctly with or without the right leg
electrode attached. However, for optimum performance, the
right leg electrode should always be used.

Warning:
Medical telemetry spectrum allocations may be assigned to
frequencies already allotted to other priority users. This means
that telemetry operations may be exposed to radio frequency
interference that may disrupt or impede telemetry patient
monitoring. Customers are urged to regularly consult with
applicable local and federal regulatory agencies (e.g., FCC, FDA,
etc.) regarding the locations and frequencies of other spectrum
users in the customer’s geographic area. Spacelabs Healthcare
Service Representatives may be able to assist you in reconfiguring
your equipment frequencies to reduce this risk of potential
interference. Spacelabs cannot, and does not, guarantee
interference-free telemetry operation.
Cautions:
• This device has a limited bandwidth from .05 to 30 Hz, which
may adversely affect the recording of high frequency
components in the ECG signal, especially when the morphology
of the ECG changes rapidly.
• This device has a limited dynamic range of ±4 mV, which may
render the device vulnerable to saturation by ECG signals with
amplitudes higher than 4 mV.
• Use only the following solutions per the manufacturer’s labeling:
Isopropyl Alcohol (70%), Hydrogen Peroxide, Cidex, Betadine,
and chlorine bleach. Use of cleaning solutions other than those
listed will VOID the warranty on the equipment cases.
• Refer to Cleaning/Disinfecting on page 4-2 for additional
instructions.
Receiver Module (90478)
The 90478 telemetry receiver module analyzes the waveform sent
by a patient-worn transmitter. This analysis consists of evaluating
dual-lead arrhythmias and ST segments. The receivers also retain
patient data such as alarm events, arrhythmia and ST-segment
trends. On the central monitor’s display, each ECG waveform zone
generally represents the user interface for one receiver module.
Receiver modules are generally inserted into a 90479-A/B/C
receiver housing. The receiver housing allows each receiver module
to be directly connected to the antenna system via input connectors
(BNC) labelled ANT 1 and ANT 2. The receiver housing is connected
to a central monitor by an SDLC cable.
The 90478-Q receiver module can also reside in a bedside monitor.
Small whip antennas attach directly to the receiver’s input
connectors. In this case, the patient-worn transmitter may wirelessly
communicate directly with the receiver module and is not required
to connect to the ceiling-mounted antenna system.

I NTRODUCTION
Each receiver module operates within a specific frequency band. A
receiver module can be tuned to any patient-worn transmitter’s
channel (operating frequency), provided the channel falls within the
same frequency band.
Monitor options provide 24 hours of trended data that can be
displayed in 2-, 6-, 12-, and 24-hour segments. Data is stored in 1minute resolution.
The receiver module counts as 1 or 2 parameters when computing
parameter capacity for monitors:
• 1 displayed ECG lead = 1 parameter
• 2 displayed ECG leads = 2 parameters
Signal reception requires the use of a different frequency (channel)
assigned to each receiver. In the U.S.A., these transmission
frequencies are regulated by the Federal Communications
Commission (FCC). In other countries, these transmissions are
regulated by the local communications authority.
Telemetry use is managed through the operation of the Ultraview
Care Network Module Configuration Manager. Refer to the Module
Configuration Manager System Administration Guide (P/N 0701245-xx), located on CD-ROM P/N 084-1101-xx.

Warnings:
• Telemetry systems may be more susceptible to interference than hardwired systems,
which may impact patient safety.
• Operation of hand-held, wireless telephone equipment (cordless telephones, cellular
telephones) near telemetry systems may cause interference and should be
discouraged. While personal communication devices are powered ON, a separation
of >6.5 feet (>2 meters) should be maintained between personal communication
devices and interior walls, the patient cables, and any electronic medical device to
which the patient may be connected. Patients should not use any type of electronic
communication equipment while connected to any electronic medical device without
an on-site evaluation by the biomedical staff. Two-way radio equipment and other
personal communication devices must be evaluated on site to determine if
additional space limitations are needed.
• Do not install a telemetry receiver module into a bedside which is currently equipped
with any other ECG module, hardwired or telemetry (or SpO
module if the 90343 or 91343 is operating with that specific receiver module). Doing
so may result in inaccurate patient data displays at remote monitors.
• Only 90478-Q modules may be installed in transport monitors.

Receiver Housing Configuration
To ready the 90479-A/B/C receiver housing for operation
1 Set the receiver housing in the area where it will be operated.
Choose a location that provides good ventilation, and ensure
that air flow for the air intake (bottom) and exhaust (rear top)
are not obstructed.
2 Verify that the receiver housing is configured for the correct AC
line voltage by inspecting the line voltage indicator on the rear
panel power entry module. The correct setting for input
voltages from 100 to 120 VAC is 115. The correct setting for
input voltages from 220 to 240 VAC is 230. If the line voltage
setting is incorrect, refer to AC Mains Voltage Selection on
page 2-8.
3 Attach the AC power cord and install the power cord retainer
(follow the instructions).
4 Cable the SDLC connections (for illustrations of other SDLC
connections, refer to SDLC Configurations on page 2-6).
a To configure SDLC connections for a typical eight-receiver
housing, connect one end of the SDLC cable to the free SDLC
port on the rear of the unit. Ensure that the SDLC terminator
is in place.
