Peltor WARNING
the sound level output from the earphones can lead to a daily exposure that exceeds permitted levels.  The audio signal in the earphones must therefore be adapted to the usage time.

To prevent harmful levels the input signal should not exceed 370mV.
370mV represents 82dBa equivalent sound level plus 1 standard deviation.

At higher levels the usage time should be reduced

The beltpack is wirelessly connected to the base unit by just pressing one button on the base unit and then one on the beltpack. You are then in conference with the other people connected to the same base.

The system is supplied in a voice-activated mode (VOX) to ensure that unwanted ambient sounds are not heard through the system.

Standard connection
The beltpack has a standard Nexus J11 connector fitted which means that is possible to use many types of headset (both dynamic and electret) without the need for any adjustments, thus making the unit adaptable for all environments.
