SM1P/B MANUAL
DOC00084 Rev.14

INTRODUCTION

The SM1P/B 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.
There are Intrinsically Safe variants of the product (“IS” and “Ex”) that meet international standards for use in explosive gas, dust, and mining environments. Please see ratings on page 37 and 38.
Situational awareness is provided by   processing 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 Sen sear’s website or your two-way radio supplier for the appropriate cable. For language translated manuals and further information, please refer to Sen sear’s website.

WEARING THE HEADSET

FIGURE 2

The SM1P/B 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 earmuffs are 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.

BEHIND-THE-NECK MOUNT FITTING INSTRUCTIONS

SIZE RANGES
WARNING Earmuffs complying with EN352-1 are of ‘small size range’, ‘Medium size range’ or ‘large size range’. ‘Medium size range’ earmuffs will fit most wearers. ‘Small size range’ or ‘large size range’ earmuffs are designed to fit  wearers for whom ‘medium size range’ earmuffs are not suitable. The SM1P/B headband, SM1P/B behind-the-neck and SM1P/B helmet adapters may be adjusted for small, medium, or large size.

MAINTENANCE AND CLEANING

The headset is an active hearing protector that allows audible contact with your surroundings while providing protection from harmful noise.
It is recommended that the headset is fitted, adjusted, and maintained in accordance with these instructions. This headset should always be worn in noisy surroundings. The headset should be regularly inspected for serviceability.

WARNING:

• If these instructions are not followed the protection of the headset will be severely impaired.
• Noise reduction will be adversely affected by anything that impairs the seal of the earmuff cushions against the head, such as thick spectacle frames and balaclavas
• The reported attenuation will be obtained only if the headset is in good condition and worn as directed (Refer to AS/NZS 1269.3 for guidance).
• This product should not be used where there is a risk that the connecting cord could be caught up during use.
• This product is provided with level-dependent in-ear audio playback. The wearer should check correct operation before use. If distortion, or failure is detected. The wearer should refer to the manufacturer’s advice for maintenance  and/or replacement.

WARNING:

• Performance may deteriorate with battery usage. The typical period of continuous use that can be expected from the headset will depend on the two-way radio battery.
• The output of the level-dependent circuit of this hearing protector may exceed the daily limit sound level. This limit can be adjusted with a Sensear programming tablet.
• This headset has been tested and approved according to the methods described in the EN352 series of standards.
