Immunity to power frequency and radio frequency fi elds
Output sound pressure level deviation when placed under the infl uence of power frequency
and radio frequency fi elds as specifi ed below:
±0.15 dB or less
• Root-mean-square electric fi eld strength up to 10 V/m (non-modulated), frequency
range 26 MHz to 1000 MHz, 900 Hz sinusoidal wave, 80% amplitude modulation
• Root-mean-square magnetic field strength up to 80 A/m, frequency 50 Hz and
60 Hz
Output sound pressure level deviation when placed under the infl uence of radio frequency
fi elds as specifi ed below:
±0.30 dB or less
• Root-mean-square electric fi eld strength up to 3 V/m (non-modulated), frequency
range 1400 MHz to 2000 MHz, 900 Hz and 1000 Hz sinusoidal wave, 80% am-
plitude modulation
• Root-mean-square electric fi eld strength up to 1 V/m (non-modulated), frequency
range 2000 MHz to 2700 MHz, 900 Hz and 1000 Hz sinusoidal wave, 80% am-
plitude modulation
The confi guration that produce minimum immunity (maximum susceptibility) to power
frequency and radio frequency fi elds:
