Environmental Considerations
Environmental Considerations
The monitor should be used in an area reasonably free from vibration, dust, corrosive or
explosive gases, and extremes of temperature and humidity. The following paragraphs give
information concerning environmental considerations.
Temperature
The monitor operates within specifications at ambient temperatures between 0 and 35
Celsius. Temperatures exceeding these limits could affect instrument accuracy and cause
damage.
Operating
Operate and store TeleMon at altitudes up to 3,048 meters (10,000 feet).

use of the monitor implies that the Telemetry System is already in place and the RF
environment has already been taken into consideration. For full coverage of this topic, refer to
the Telemetry System documentation, especially Chapter 2 of the Service Guide.
Warning
Warning
TeleMon units containing transmitters that are 25 kHz apart in transmitter frequency
interfere with one another at distances of 1-3 feet. This situation is aggravated by ECG
cable proximity. Symptoms include dropout (at the information center), waveform
artifact of the ECG (at central and TeleMon), and screen freeze (at TeleMon). To avoid
this situation, maintain a distance of >3 feet between TeleMon units.
