Guidance and manufacturer s declaration electromagnetic immunity (conducted RF) Test IEC Test Level 2 Immunity Compliance Level Electromagnetic Environment - Guidance Electromagnetic site survey- 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 of the location in which the activator is used exceeds the applicable RF compliance level above, the activator should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the activator. RF Operating Frequencies Nearby or hidden equipment emitting strong magnetic fields, such as Radio-Frequency IDentification (RFID) emitters, other medical and radio devices, etc., can interfere with inductive and RF communication of the activator, even if the other equipment complies with applicable emission requirements. If interference occurs, you can minimize its effect by reorienting or relocating the activator or by shielding its location. The operating characteristics of the activator are as follows: Inductive Telemetry - RF Transmission Carrier frequency at 60 khz (inductive telemetry). - RF Reception Centered at 60 khz (inductive telemetry).
