6:3 Sound exposure when using audio input J22 (F)
6:4 Sound exposure when using the 3.5 mm audio input
The earphone level for music is measured at no more than 82 dB(A) equivalent
sound level. Max input level 1,5 Vrms.
6:5 Criterion levels (G)
A criterion level is the amount of noise (measured as A-weighted sound
pressure) outside the hearing protector that gives 85 dB(A) inside. The noise
level depends on the type of noise. H is high-frequency dominated noise, M
is noise that is not dominated by any given frequency, and L is low-frequency
dominated noise.
6:6 Battery type
All types of AAA 1.2–1.5V batteries can be used (NiMH, NiCd, Alkaline, Lithium,
Manganese, etc), but only NiMH and NiCd batteries can be recharged.
6:7 Battery life
The expected battery life may vary depending on the brand of batteries and the
temperature in which the product is used. Low battery level is indicated by a
voice saying:
“low battery”. The headset functions will not work optimally
if the battery is low.
