INTRODUCTION
Attention Installer: To assure a trouble free installation, please read
these entire instructions through once before beginning.
The Sigtronics Mobile Radio Interface Module is a small unit that allows
emergency personnel to operate the vehicle’s mobile radio using a
headset. When used with a Sigtronics noise attenuating headset (ie.
models SE-8 or SE-48) this unit provides personnel with clear radio
communications in high noise environments. The system allows full
radio monitoring as well as radio transmit capability from the headset
via a Push-To-Talk (PTT) switch.
Applications: The unit is designed for fire apparatus, rescue and
ambulance vehicles, marine emergency equipment, airport ground
vehicles, and mobile emergency command centers. Used in applications
where intercom is either not desired or not necessary.
Headphone Output: The Mobile Radio Interface Module is designed
to be used with noise attenuating, full cushion headsets, such as the
Sigtronics SE-8, or SE-48. The Mobile Radio Interface Module incorporates
an automatic headphone limiting circuit to eliminate the possibility of
painful spurious radio or noise spikes from getting to the headset and
to your ears.
Universal Radio Interface is designed to accommodate virtually any type
of communication radio. Adjustments for radio transmit microphone
level are provided to perfectly match the Mobile Radio Interface Module
to your particular radio.
Excellent RF Immunity guarantees clean, clear, radio communications.
Standardized for use with Sigtronics single plug headsets (ie. SE-8,
SE-18, or SE-48).
