USING THE HEADSETS
SETTINGS
The SM1P/B 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, Bluetooth® (cellular or
wired connection), or Short-Range Technology. There are intrinsically
safe variants of the product (IS and Ex) that meet 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 SRCK6xxx02 cable or the intrinsically safe SRCK6xxxCx02 cable
assemblies (available separately). 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.
SENS® (Speech Enhancement Noise Suppression) Technology
When headset is powered on, it is automatically in SENS® mode (allows
360° situational awareness in addition to communication). By pressing
the power button, you can toggle between SENS® mode and Quiet
mode. The volume control buttons can be used to raise or lower the
audio level of SENS®.
Two-Way Radio
To transmit over two-way radio, press and hold the button on the inline
PTT. Release the inline PTT to cease transmission. To change the volume
of the two-way radio communications, use the two-way radio’s volume
controls.
Short-Range
Short press the volume buttons simultaneously to toggle Short-Range
on/off. Use the multi-function button (MFB) to PTT in Short-Range.
Increase/decrease the preset frequency banks by long pressing the
volume buttons.
Bluetooth®
Press and hold the MFB to pair headset with device. You will hear
“Bluetooth® discoverable” when in pairing mode. You will hear a
connection tone if connection is successful (Note: Short-Range must be
turned off to use MFB for Bluetooth® pairing). Press and release MFB to
answer incoming call; press and hold MFB to reject incoming call or end
call.
VOX
VOX can be used on VOX-enabled two-way radios. To disable VOX, you
can either turn VOX off on the two-way radio or press the headset PTT
once (depending on two-way radio model) . If VOX is assigned to Short-
Range, when Short-Range turns on, you will hear the Short-Range
frequency announcement and then “VOX on.” VOX can be toggled on
and off by short pressing the volume down button and power button
simultaneously.
