INTRODUCTION
The SM1P/PW/B/DP/XBT Ex Series of Headsets is a state-of-the-art
hearing protection (i.e., protects against harmful noise)
communication system that allows you to retain situational awareness
whilst remaining in full contact with your team via Short- Range
technology, as well as two-way radio or cellular device via Bluetooth®
or wired connection.
The product meets the following international standards for use in
explosive gas, dust, and mining environments. Check the product label
to identify the ratings applicable to the headset.

Situational awareness is provided by processing technology and
environmental microphones mounted within the headset.
Connection through intrinsically safe communication devices is
enabled by the SRCK61xxCCxx or SRCK62xxCCxx cable assemblies
(available separately). Cable part numbers vary depending on the
communication device connector. Please consult Sensear’s website or
your communications supplier for the appropriate cable.
For language translated manuals and further information, please refer

The SM1P-Ex headset is designed to be worn with the headset sealing
around the ears. Specific examples of how to fit the headset around the
ears are covered in the next three pages. The fit does alter slightly
depending on what style of brace is used - Headband, Behind-the-Neck,
or Helmet mounted.
The boom microphone should be placed approximately 5mm (1/4”) in
front of the mouth. Check to ensure the white dot or microphone label is
facing towards you. The orientation is essential as the microphone is
directional. If the microphone faces a different direction, this may lead to
a reduction in transmission quality.
The inline PTT has a rotatable clip behind it to allow it to attach to the
shirt / upper garment. The inline PTT must be connected to the two-way
radio using the multi-pin connector.
FITTING THE HEADSET
It is recommended that the wearer should ensure that:
•The earmuffs are fitted, adjusted, and maintained in accordance with
the manufacturer’s instructions
•The earmuffs are always worn inhigh noise conditions
If the above recommendations are not adhered to, the protection
afforded by the earmuffs will be severely impaired.

COMMUNICATING
COMMUNICATING OVER TWO-WAYRADIO:
Only approved two-way radio cables (SRCK61xxCCxx) or adaptor cables
(SRCK62xxCCxx) containing a certified IS barrier may be used with SM1P-
Ex and SM1P-ExDP models.
To Transmit Over Two-Way Radio:
• Press and hold the button located on the inline PTT
• Release the inline PTT button to cease transmission
• To change thevolume of the two-way radio communications, use
the two-way radio’s volume controls
NOTE:
•When the headset is powered off (and disconnected from the
inline PTT), the inline PTT button may not activate the two-
way radio. The PTT located on the two-way radio should be
used.
•When the headset is powered on, the two-way radio PTT may
not activate the two-way radio
•Audio will revert to radio when the headset connector is
disconnected (dependent on radio type and compatible SRCK
radio cable)
Two-Way Radio VOX: VOX can be used on VOX-enabled two-way radios.
Refer to the two-way radio documentation for the setup and use of the
VOX feature. To disable VOX, you can either turn VOX off on the two-way
radio or press the headset PTT once, depending on which two-way radio
model you use.
