Sensear SP1R State of the Art Hearing Protection Communication System

Sensear-SP1R-State-of-the-Art-Hearing-Protection-Communication-System-
PRODUCT

The SP1R is a state-of-the-art hearing protection communication system designed to protect against harmful noise while allowing you to retain situational awareness and communicate with your team through two-way radio communication. The SP1R has an Intrinsically Safe variant that meets international standards for use in explosive gas environments. The headset provides situational awareness through processing technology and environmental microphones mounted within the headset. The SP1R draws power from the two-way radio and must be connected by the appropriate SRCK7xxx radio cable to utilize both situational awareness and two-way radio communications.

**PRODUCT Fitting the Earplugs

**

The SP1R comes with a detachable earpiece assembly designed for ease of serviceability and hygiene for users who share the base unit. To fit the earplugs, follow these steps:

Place disposable foam tip between thumb and forefinger.
Roll foam tip to a compressed, crease-free cylinder.
Push the foam tip all the way onto the earpiece spout.
Roll the foam tip again between the thumb and forefinger.
Ensure the foam tip remains a compressed crease-free cylinder.
Using your opposite hand, pull your ear upward and outward.
Insert the earpiece and hold in place for 30 seconds while the foam tip expands.

PRODUCT Operating the Headset

To turn on the headset, follow these steps:

Connect the SRCK7xxx radio cable to the Hirose connector on the bottom of the main unit.
Connect the SRCK7xxx cable to the two-way radio.
Turn the two-way radio on.
The headset will power up. An audible “Sensear, sounds good to me” will be heard through the headset.

To turn off the headset, either turn off the two-way radio or disconnect the headset cable from the SRCK7xxx cable. The environmental and quiet modes can be turned on and off by turning the volume knob to the on/off position with a click, which will toggle the unit into mode or quiet mode while also controlling the volume level. This allows for easy muting of Sensear’s situational awareness feature when, and if, this is preferred by the user.

INTRODUCTION

The SP1R is a state-of-the-art hearing protection (i.e., protects against harmful noise) communication system that allows you to retain situational awareness while 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 environments. Situational awareness is provided by SENS processing technology and environmental microphones mounted within the headset. The SP1R headset draws power from the two-way radio. It must be connected by the appropriate SRCK7xxx radio cable to utilize both SENS situational awareness and two-way radio communications. SRCK7xxx part numbers vary depending on the radio connector and are sold separately. For language-translated manuals and further information, please refer to the website.

The SP1R is designed to be worn with the main housing attaching to the belt of pant seam, and the inline PTT attaching to the shirt/upper garment. Sensear-
