Ultraview Digital Telemetry
3
General Telemetry Overview
The 90478-A digital telemetry receiver module, when used in conjunction with
Spacelabs Medical telemetry transmitters, an Ultraview
™
monitor, and 90479-A
modular receiver housing, provides continuous monitoring of electrocardiographic
signals in order to detect abnormal cardiac rhythms, including asystole, ventricular
fibrillation, and ventricular tachycardia. In addition, when used with the 90343
digital telemetry multi-parameter transmitter and the 90217 Ambulatory Blood
Pressure (ABP) monitor, monitoring of electrocardiographic signals is augmented
by the availability of continuous or episodic SpO
2
measurements and episodic
noninvasive blood pressure (NIBP) measurements.

• Spacelabs Medical’s telemetry equipment complies with part 15
(602 to 620 MHz operation) and part 95 (608-614 MHz
operation—Wireless Medical Telemetry Service) of the FCC
Rules and with RSS-210 of Industry Canada. Repeated here
are operational cautions for biomedical telemetry from the FCC
Rules (47CFR15.242(f)):
“Biomedical telemetry devices must not cause harmful
interference to licensed TV broadcast stations or to other
authorized radio services, such as operations on the
broadcast frequencies under subpart G and H of part 74 of
this chapter, land mobile stations operating under part 90 of
this chapter in the 470-512 MHz band, and radio astronomy
operation in the 608-614 MHz band. (See section 15.5). If
harmful interference occurs, the interference must either be
corrected or the device must immediately cease operation
on the occupied frequency. Further, the operator of the
biomedical telemetry device must accept whatever level of
intereference is received from other radio operations. The
operator, i.e., the health care facility, is responsible for
resolving any interference that occurs subsequent to the
installation of these devices.”
• Medical telemetry equipment is only for installation and use in
hospitals and health care facilities. It is not permitted for use in
vehicles that operate outside of the medical facility premises.
The user of this equipment is not authorized to make any
changes or alterations that could compromise the national
certifications.
• Unlicensed low power operation of biomedical telemetry is on a
no-protection and no-interference basis. Biomedical telemetry
operations are listed as a secondary allocation to VHF/UHF
television broadcast and are listed as co-primary allocation to
radio astronomy services (608-614 MHz). Additionally, some
frequency bands may be shared with amateur radio operations
and other unlicensed low power devices.
• Operation of telemetry equipment in the 608-614 MHz band
may be geographically restricted by government regulation.
Spacelabs Medical Customer Service can assist in evaluating if
a hospital’s location requires coordination with a protected radio
astronomy observatory that may be within 80 Km (50 mile)
radius.
