OTTO NoizeBarrier Micro Comms Kit V4-11029 Manual

INTRODUCTION

The NoizeBarrier^® Micro Comms Kit comes in three different Surveillance Kit options; Single Ear Kit and optional ear plug, Enhanced Single Ear Comms Kit with transducer, or Enhanced Dual Ear Comms Kit with transducer.

INSTALLATION

EARTIPS

All options come with eartips designed specifically to work with OTTO's NoizeBarrier^® Micro electronic earplugs. There are two stems in the back of each eartip, a STRAIGHT stem, and an ANGLED stem.

1. Install the eartip of the NoizeBarrier^® Micro by inserting it into the STRAIGHT stem of the eartip.
2. There are two installation options:
   1. In option A install the OTTO acoustic tube to the ANGLED stem of the eartip. The tube should be rotated until it points upward at a right angle from the Micro body.
      
   2. In option B-for wired kits, install the transducer to the ANGLED stem of the eartip. The wire should be rotated until it points upward at a right angle from the Micro body and fits securely around the outer ear.
      
3. When the Micro is inserted into the ear, the larger portion of the Micro body should angle towards the rear of the cochlea, with the curved windscreen facing forward to the user's face.

SINGLE EAR KIT

Please refer to the Eartip Installation section before beginning the next steps.

1. Adjust the acoustic tube so that it will rise vertically over the top of the ear, curve over, and direct back towards the nape of the neck.
2. Install the acoustic tube into an earphone or surveillance kit as usual.
   The volume of communications received can be controlled by the radio.

ENHANCED SINGLE AND DUAL EAR KITS

1. Refer to the Eartip Installation and confirm proper eartip placement.
2. Follow Single Ear Acoustic Tube Installation directions.

To change the transducer:

1. Holding the earphone assembly cable, rotate down and out of the strain relief holder pulling it straight out of the transducer.
2. Push the clothing clip out to a 90° angle revealing the open slot.
3. Insert a flat object (like a flat-head screwdriver) into the opening and pry the transducer off. Snap the new transducer in its place.
4. Plug the cable into the new transducer (Note that the 2 pins on the cable are different sizes and will only fit back into the transducer one way). Rotate the wire back into the strain relief holder securely.
   

POWERING ON/OFF

Consult the NoizeBarrier^® Micro user guide for directions on how to properly power on and off the Micro.

HEARING PROTECTION WARNING

OTTO products are designed to produce a specific audio output level at maximum rated power. Modifying these devices in any way including adding or removing components or accessories may change the audio output of the device and could result in PERMANENT HEARING DAMAGE. Many countries have regulations defining the amount of noise that an individual can be subjected to during a normal workday. The duration of exposure, the level of audio output, and the level of ambient noise will affect compliance with these regulations. Compliance is application dependent and standards vary. It is the SOLE RESPONSIBILITY of the end-user to determine the applicability of and compliance with local hearing protection regulations. Also, if purchasing any OTTO accessories which use earphone kits, it is the SOLE RESPONSIBILITY of the user to determine proper fit. Always use caution when inserting any of the products into your ear.
