Thank you for your purchase of this product.
KAIROS comes out from the best Italian tradition, where all details, also the invisible ones, are important and
need a care. Designing a mobile radio
infrastructure is an art, that needs a complete
knowledge of all the possible aspects to avoid
unexpected situations. Our long experience in
building infrastructure has generated this
professional transceiver: the right building
block for a number of applications ranging from
a simple standalone repeater to a national wide
system. We solved the complexity to ease your
creativity.
