Caution
The TeleMon NBP may not operate correctly if used or stored outside the
relevant temperature or humidity ranges.
Caution
Do not use any abrasive cleaning materials on any part or component of the
TeleMon. Do not clean any part or component of the TeleMon in any overly
vigorous or abrasive fashion. Using abrasive cleansers and abrasive cleaning
actions will damage the components.
Caution
Remove the battery and any cables or accessories before you clean TeleMon.
Caution
Conductive parts of electrodes should not contact earth or other conductive
parts.
The electromagnetic compatibility (EMC) validation of the M2636B TeleMon
Monitor included tests performed according to the international standard for EMC
with medical devices. See the Manufacturer's Declaration for details.
During the test program, the M2636B was subjected to many EMC tests, both
international standard and our proprietary tests. During most of the testing, no
anomalies were observed, except for some immunity tests which required reduced
levels of the external influence for compliance.
EN 61000-4-3 specifies that the product be subjected to an electromagnetic field of 3
V/m over a frequency range of 26 to 1000 MHz with no degradation of performance.
At most of the test frequencies in this specified range, no anomalies were observed.
However, at the product transmit/receive frequency, and a few others, the radiated
field imposed caused interference with a resultant drop-out of ECG and pleth signal.
For frequencies in the range of 108.89 MHz to 223 MHz a reduced level of 1.0 V/m
was met, and in the range of 311 MHz to 601 MHz a reduced level of 1.6 V/m was
met, with no anomalies.
The IEC 801-2 Electrostatic Discharge Test calls for the product to withstand air
discharges at up to 8 kV, and contact discharges to exposed metal on the M2636B or
to a nearby metal plate at voltage settings up to 4 kV with no change of operating
state. The M2636B passes the air discharge test and contact discharge tests at a
