Table 4: Guidance and Manufacturer's Declaration - Electromagnetic Immunity
The ConMed Linvatec VP4726 and VP4726F Monitors are intended for use in the electromagnetic
environment specified below. The customer or the user of this VP4726 or VP4726F Monitor
Immunity Test
Radiated RF
IEC 61000-4-3
Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects, and/or people.

Field strengths from fixed transmitters, such as base stations for radio (cellular / cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically
with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic
site survey should be considered. If the measured field strength in the location in which the VP4726 and
VP4726F Monitors are used exceeds the applicable RF compliance level above, the VP4726 and VP4726F
Monitors should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the VP4726 and VP4726F Monitors.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
