Putting the UI 770 into operation
The UI 770 universal interface is a special version featuring
a reduced output level. Even with the volume of the UI 770
set to the maximum, the signal transmitted by the connected
Sennheiser Communications headset will never exceed the
maximum of 85 dB(A) per day as a time-weighted average*
value, which is in compliance with the EU Noise Directive**.
* The time-weighted average value is based on a breakdown
of a typical working day and measured as the sound pressure
level with a B&K HATS (Head And Torso Simulator).
** EU Directive 2003/10/EC on the minimum health and
safety requirements regarding the exposure of workers to the
risks arising from physical agents (noise).
