Overview of Telemetry Systems: About Your System
About Your System
Due to continuing product innovations, there are three versions of the
Model 340 Telemetry System in hospitals today. All three versions
operate identically from a user’s perspective. Unless otherwise indicated,
the information in this manual applies to all three devices.
Model 340 Original Release
The first release of the Model 340 Telemetry System operates in the
frequency range 430–470 MHz.
Model 340 Plus
The Model 340 Plus also operates in the frequency range 430–470 MHz
offering additional channel numbers than the original Model 340. In
addition, the Model 340 Plus offers flexibility by allowing factory re-
programming to an alternative channel number should interference
become a factor in your location.
Model 340M
The Model 340M operates in the frequency range 608–614 MHz where
the “M” indicates “medical”. The Model 340M complies with the Federal
Communications Commission (FCC) rules for Wireless Medical
Telemetry Service (WMTS). In June 2000, the FCC allocated a new
spectrum allowing potentially life-critical equipment to operate on an
interference-protected basis. Refer to “Wireless Medical Telemetry
Service” on page 1-10 in this manual for additional information.

Overview of Telemetry Systems: Identifying Your System
Identifying Your System
Each GE Medical Systems Information Technologies device has a unique
serial number tag for identification. For each Model 340 Telemetry
System, a reference number can be used to determine if the unit is a
Model 340 Original Release, Model 340 Plus, or Model 340M. If your

LINE ISOLATION MONITOR TRANSIENTS—Line
isolation monitor transients may resemble actual cardiac
waveforms, and thus cause incorrect heart rate
determinations and alarm activation (or inhibition).
MRI USE—Do not use the equipment during MRI
scanning; conducted current could potentially cause
burns.
PATIENT CABLES AND LEADWIRES—Do not use
patient cables and electrode leads that permit direct
connection to electrical sources. Use only “safety” cables
and leadwires. Use of non-safety patient cables and lead
wires creates risk of inappropriate electrical connection
which may cause patient shock or death.
PACEMAKER PATIENTS—Rate meters may continue to
count the pacemaker rate during occurrences of cardiac
arrest or some arrhythmias. Do not rely entirely upon
rate meter alarms. Keep pacemaker patients under close
surveillance. Refer to your monitor’s operator’s manual
for disclosure of the pacemaker pulse rejection capability.
SIMULTANEOUS DEVICES—Do not simultaneously
connect more than one device that uses electrodes to
detect ECG and/or respiration to the same patient. Use
of more than one device in this manner may cause
improper operation of one or more of the devices.
STRANGULATION—Make sure all patient cables,
leadwires, and tubing are positioned away from the
patient’s head to minimize the risk of accidental
strangulation.
WATER BIRTHS—Do not use a fetal or maternal/fetal
monitor to directly monitor patients during water
births, in whirlpool or submersion water baths, during
showers, or in any other situation where the mother is
immersed in water. Doing so may result in electrical

This section applies to Model 340M Telemetry Systems only. Refer to
“Identifying Your System” on page xi for information about identifying
what type of telemetry system you have in your hospital.
,03257$17
Operation of a Model 340M Telemetry System requires
prior coordination with a frequency coordinator
designated by the FCC for the Wireless Medical
Telemetry Service.
In June 2000, the FCC allocated new spectrum and established rules for
Wireless Medical Telemetry Service (WMTS) allowing potentially life-
critical equipment to operate on an interference-protected basis.
The frequency allocation for WMTS provides spectrum where the
equipment can operate on a primary basis increasing the reliability of
this important service. The FCC allocated 14 MHz of spectrum for use by
medical telemetry equipment in the 608–614 MHz, 1395–1400 MHz, and
1429–1432 MHz bands. This allocation was based on a needs assessment
conducted by the American Hospital Association (AHA).
The 608–614 MHz band, which corresponds to TV channel 37 had been
reserved for radio astronomy uses, so this action elevates medical
telemetry to a co-primary status with radio astronomy in this band. The
1395–1400 MHz and 1429–1432 MHz bands were government bands
reallocated for non-government use.
WMTS is designated as one of the Citizen’s Band Services in Part 95 of
the rules and licensed by rule to eliminate the possible costs and delays
to obtain individual operator’s licenses. The medical telemetry
equipment is authorized under the certification procedure in Part 2 of
the rules. One or more frequency coordinators maintain a database of all
equipment used in conjunction with WMTS.
