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.
