INTRODUCTION
The SM1P is a state of the art hearing protection 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.
Situational awareness is provided by processing technology
and environmental microphones mounted within the headset.
Contact through two-way radios is enabled by the SRCK61XX*
cable assembly available separately. Cable numbers vary
depending on the two-way radio model. Please consult with the
website for more information.
*SRCK61XX part numbers vary depending on the radio connector.
Consult your supplier for the appropriate cable.
For language translated manuals and further information, please
refer to the website.

WEARING THE HEADSET
The SM1P 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 mounted to a helmet directly.
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 ear muffs are fitted, adjusted and maintained in
accordance with the manufacturer’s instructions
The ear muffs are worn at all times in high noise conditions
If the above recommendations are not adhered to, the protection
afforded by the ear muffs will be severely impaired.
