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 people.
3. 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 15MX/19MX
Touchcomputer for Healthcare Applications is used exceeds the applicable RF compliance
level above, the 15MX/19MX Touchcomputer for Healthcare Applications should be
observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the 15MX/19MX
Touchcomputer for Healthcare Applications.
4. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 Vrms.
