Passive hearing protectors remove the surrounding
sounds, eg alarms and warning signals, this can effectively decrease
safety in certain work situations.
Local permits normal comprehension of surrounding
sounds. Sensitive microphones catch the surrounding sound
with full stereo effect. At a low noise level weak sounds are amplified
and at high noise levels sounds is limited to 80 dB(A)
through the electronics.

In many situations there could be several teams in an
area and need for teamleaders of supervisors to communicate
with each team.
Local makes it
possible to easily communicate and instruct each team without disturbing
the others, simply by changing between channels. As long as all in
each teams are within the range of the built-in tranceivers, then the numbers of
users in each group is in theory unlimited.

Local is a radio for medium distance communication.
Using the very latest high technology circuitry Local now makes
it possible to effectively and clearly communcate at distances
up to approximately 2 kilometres (433/1 kilometre).
Range will always be dependent on topography, however,
the frequency band used on the Local is relatively insensitive to
the screening effect of steel and concrete. For longer distances
we recommend Regional or Global.

The Local headset is equipped with a unique single
button which allows the wearer to make all changes between VOX (low,
medium or high) /PTT
and channel, without compromising the hearing protection.
With one and the same button you can make all necessary
changes and a voice will tell you either what selection you have
made, or as a check, it will tell you what mode and channel you
have selected.
