Jabra BT5020 - Manual (Page 5)

Do Jabra Multiuse solutions protect users against noise?
Yes. The Jabra Bluetooth hub/dongle protects against loud sounds e.g. the high- •
pitched squeals of a fax machine that may be harmful. Many acoustic experts
define acoustic shock as exposure to levels in excess of 135 dB SPL, but even
lower can damage the ears. Therefore, Jabra Multiuse solutions cut off sounds at
118 dB SPL (RMS).
Can Wi-Fi and the Jabra Bluetooth hub coexist in the same location?
Yes, the Jabra Bluetooth hub uses adaptive frequency hopping, so that channels •
that are blocked by Wi-Fi, etc… will not be used – only the free channels are used
to ensure good sound quality.
Is radiation from a wireless headset dangerous?
Jabra Multiuse solutions employ radio signals in the 2.4 GHz frequency band •
using the Bluetooth protocol for transmission. The radio wave exposure from the
JX10 with Bluetooth hub/dongle is 2.5 mW and well below national standards.
What is DSP (Digital Signal Processing)?
A digital processor enhances the incoming voice/audio signal and removes sound •
impurities from noisy environments, mobile phones, etc... All Jabra Multiuse
headsets as well as the Jabra Bluetooth hub are using DSP (except Jabra BT5010).
