INTRODUCTION
The SM1R 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
two-way radio communication.
There is an Intrinsically Safe variant of the product that meets international
standards for use in explosive gas, dust, and mining environments.
Situational awareness is provided by processing technology and
environmental microphones mounted within the headset.
Contact through two-way radios is enabled by the SRCK60xx* cable
assembly available separately.
Please note that the SM1R headset uses power from the two-way radio.
The SM1R must be connected by the appropriate SRCK60xx cable to the
radio to provide both situational awareness and communication to
the two-way radio.
*SRCK60xx part numbers vary depending on the radio connector. Consult
your supplier for the appropriate cable.

The SM1R 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 mount 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 earmuffsare fitted, adjusted, and maintained in accordance
with the manufacturer’s instructions
•The earmuffs are always worn in high noise conditions
If the above recommendations are not adhered to, the protection afforded
by the earmuffs will be severely impaired.
