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 absorp-
tion and reflection from structures, objects, and people.
Table C.9: Guidance and manufacturer's declaration – electromagnetic immunity for the battery charger
1. 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 mea-
sured field strength in the location in which the battery charger is used exceeds the applicable RF compliance level above, the
battery charger should be observed to verify normal operation. If abnormal performance is observed, additional measures
may be necessary, such as re-orienting or relocating the battery charger.
2. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
