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.
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.

instructions.
