USING THE HEADSETS
The SM1R is a state-of-the-art hearing protection and communication
system that allows you to retain situational awareness while
remaining in full contact with your team via two-way radio
communication. There is an intrinsically safe variant of the product
that meets international standards for use in gas, dust, and mining
environments. Situational awareness is provided by SENS®
Technology and environmental microphones mounted within the
headset. Contact through two-way radios is enabled by the SRCK60xx
cable or the intrinsically safe SRCK60xxx001 cable assemblies
(available separately).
Please note that the SM1R uses power from the two-way radio and
must be connected by the appropriate SRCK60xx cable to the radio to
provide both SENS® situational awareness and communication to the
two-way radio. Cable part numbers vary depending on the two-way
radio model connector. Please consult Sensear's website or your two-
way radio supplier for the appropriate cable. For further information,
please refer to Sensear's website.
