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

specically 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.

1Install the eartip of the NoizeBarrier® Micro by

inserting it into the STRAIGHT stem of the eartip.

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.

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 ts securely

around the outer ear.

3When 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.

HEARING PROTECTION WARNING

OTTO products are designed to produce a specic 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 dening 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 t. Always use caution when inserting any of the

products into your ear.

POWERING ON/OFF
