Page 6: Introduction
INTRODUCTION The Series 9100 Digital Intercom System was designed as a simple, versatile and user-friendly crew communication solution, and built to withstand the harshest environments in a multitude of real-world applications. The key to optimal, long-term performance of the system, however, lies with the user and their understanding and adherence to the proper use and care of the system as provided. -
Page 7: Headsets
HEADSETS Proper Fit and Adjustment Proper fit of your headset is critical to both its communication performance and noise attenuation effectiveness (latter is not applicable to single-ear models). Consult the instructions below for proper fit. Over-The-Head Styles (H9130, H9180, H9190) For models worn over-the-head, first open the headband adjustment all the way and fit the headset over your ears. -
Page 8: Bth Styles
Tightening of the locknuts where the headband spring meets the stirrup assemblies (or temple pad assembly for single ear model) will provide a more permanent fit for private issue headsets. The use of eyeglasses/sunglasses will reduce the attenuation afforded by this device, due to noise leakage at the points where the temples of your glasses create a gap at the ear seals. -
Page 9: Microphone Adjustment
Microphone Adjustment Microphone booms on Series 9100 Headsets are hybrid style, in that the lower half is a hinged wire type (where it meets the ear cup), mated to a bendable flex boom (terminates in the microphone bracket). On over-the-head style Headsets, microphone booms can be rotated 280°, so as to be worn on either the user’s left or right side. -
Page 10: Volume Adjustment
Volume Adjustment Each ear is equipped with a rotating volume control knob, wired independently (dual-ear models.) Adjust each knob accordingly for the volume in each individual ear (Note: see User Manual P/N 19602P-31 for volume adjustments on Model H9140-HT headset) Headset Connection/Disconnection Connecting a headset to a powered headset station or wireless belt station will automatically power all headset electrical features, and disconnection from same will disable these features. -

4.) Pull opposite half of ear seal over the opposite curve in the ear cup ridge, until inner lip of ear seal is stretched completely over the ridge on both ends, then release and repeat steps 2 through 4 on the opposite side of the headset. 5.) Ensure all inner headset filters are installed appropriately. -
Page 12: Replacing Microphones And Microphone Windscreen Kits
Replacing Microphones and Microphone Windscreen Kits Both the Series 9100 Microphones (Model M-2H, P/N 09168P-76) and variants of their respective Windscreen Kits (stock kit P/N 41090G-23; High Wind Mic Cover Kit P/N 41090G-24) are immersion-proof assemblies, and for hygiene purposes each can be either cleaned with mild soap and water, as well as wiped down with commercial alcohol wipes (such as 70% isopropyl) to kill germs. -
Page 13: Headset Cleaning
Proper Cleaning and Application of Corrosion Inhibitors The user’s Headset, in most cases, is the most exposed component of the Digital Intercom System. Exposure to elements such as salt fog, water and wind-driven particles will work to wear away or corrode any type of marine-grade steel, even stainless steel or aluminum. Fortunately, simple periodic cleaning and appropriate care of the headsets’... -
Page 14: Use Of Cloth Covers (Ear Seals, Head Pad)
Use of Cloth Covers for Head Pads (OTH models) and Ear Seals Further hygiene measures can be applied for OTH style head pads (cloth comfort cover for OTH head pad, P/N 18981G-01 (see Figure 9) and for ear seals cloth cover, pair, P/N 22658G-01). These soft, cotton covers are washable with mild soap and water, and work to keep the user comfortably protected from “hot spots”... -

Should a dust cap be missing or recently broken off of its tether, contact your David Clark reseller to discuss replacing this cap immediately (see Figure 11) Even properly protected, the connector will be subject to water exposure eventually, putting the individual conductors at risk of tarnish or premature corrosion. -
Page 16: Module Surfaces
Module Surfaces With headset connector dust caps firmly in place and network connectors fully secured with IP- rated connector housings, all exposed surfaces of Headset Stations and Wireless Gateways can be wiped down with a clean cloth and washed with a mild soap and water mixture. Liquid dish detergents are good examples of mild soaps that do not leave a residue when rinsed away with water. -
Page 17: Disconnection/Connection Of Power Cable
The unit lid can then be wiped down carefully with a mild soap and moistened swab, avoiding any moisture to enter the well of any connector, and carefully dried. The remainder of the enclosure can also be cleaned with soap and water, where needed. Once dry, the Master Station can be re-secured to its original mounted position and all previous cables reconnected as prior. -
Page 18: Disconnection/Connection Of Radio, Auxiliary Cables
Radio and/or auxiliary cable ends terminating in non-David Clark audio accessories (i.e., two-way radios, recorders, etc.) should not require disconnection after installation unless it is to replace the accessory unit, and therefore should not require maintenance or cleaning. -

slick to the touch. Proper storage of the unit after use will effectively protect the belt station from harmful UV rays. Figure 14: Wireless Belt Station (without rubber skin) Battery Management Wireless Belt Stations are powered by Lithium Ion rechargeable batteries (P/N 40688G-90). A relatively new battery within its warranty term (1 year from purchase, 2 years from date code on the battery label) should nominally provide 24 hours of continual use on a charge and will recharge from a fully depleted state within roughly a few hours with the use of the 4-Bay... - Page 20 Charging Units are not rated for marine use and as such, measures should be taken to fully and completely protect charging units from the elements or else should only be deployed on shore in an office environment. Charging Units should be periodically inspected for debris or residue inside the battery compartments and/or on the charging terminals.

Page 21: Storage Considerations (Headsets, Wireless Belt Stations)
David Clark also offers a Headset Carry Case (P/N 40688G-08, see Figure 17) suitable to store a single 9100 Series Headset, as well as a single Wireless Belt Station, when not in operation. Keeping the Headset and/or Wireless Belt Station in a fully-zipped Carry Case after each use will significantly improve the environmental protection of these items, provided they are, in turn, to be stored in an area onboard the vessel protected from water and direct sunlight. -
