Guide d'information et déclaration du fabricant – immunité électromagnétique (2)
NOTE 1 At 80MHz and 800MHz, 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.
a
Les champs de force 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 Otowave 102 Tympanometer is
used exceeds the applicable RF compliance level above, the Otowave 102 Tympanometer should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the Otowave 102 Tympanometer.
b
over the frequency range 150 kHz to 80 MHz, field strengths
should be less than 3 V/m.
Distances de séparation recommandées entre équipement portable et mobile de communications RF et le
tympanomètre Otowave 102
Le tympanomètre Otowave 102 est prévu pour un usage dans le milieu électromagnétique dans lequel sont
contrôlées les perturbations de radiation RF. Le client ou l'utilisateur du tympanomètre Otowave 102 peut éviter
les interférences électromagnétiques en maintenant une distance minimum entre tout équipement portable et
mobile de communications RF (émetteurs) et le tympanomètre Otowave 102 comme conseillé ci-dessous.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in
metres (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the
maximum output power rating of the transmitter in Watts (W) according to the transmitter manufacturer.
NOTE 1 At 80MHz and 800MHz, the separation distance for the higher frequency range applies.
