Should be less than the compliance level in each frequency range. b. Interference may occur in the vicinity of equipment marked with the following symbol: Note .. At 80 MHz and 800 MHz, the higher frequency range applies. .. These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and 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 sur vey should be considered. If the measured field strength in the location in which the monitor is used exceeds the applicable RF compliance level above, the monitor should be obser ved to verify normal operation. If abnormal performance is obser ved, additional measures may be necessar y, such as reorienting or relocating the monitor. .. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m. 4 1. Important Recommended separation distances between portable and mobile RF communications equipment and the EQUIPMENT or SYSTEM – for EQUIPMENT and SYSTEMS that are not LIFE-SUPPORTING: The monitor is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.The customer or the user of the monitor can help prevent electromagnetic interference by maintaining a minimum distance between por table and mobile RF communications equipment (transmitters) and the monitor as recommended below, according to the maximum output power of the communications equipment.
