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.
This Component Maintenance Manual is intended to provide the knowledge and guidance necessary to properly use and maintain the Series 9100 system components, and is written in the context of marine installations, as this represents the majority of likely applications, as well as the most susceptible to the widest array - and harshest - of environmental exposure.
The majority of usage information on the system itself is found in detail within the Series 9100 Operation/Installation Manual (doc. #19549P-31), to which this CMM is supplemental. The exception is where knowledge pertaining to the proper use and care of Headsets in general are concerned. To this end, this CMM begins with comprehensive information related to the Headset, being the most personal and immediately necessary component for each user, and also the most susceptible to misuse, abuse and exposure to the elements.
From there, the CMM covers the necessary maintenance information for the other system components that are subject to at least partial exposure to environmental stresses and neglect from lack of cleaning, from Headset Stations to Wireless Gateways and Belt Stations.
Also included is a brief section of the least exposed components of the system, namely the Master Station, its installed add-in cards and system cabling. Related information is largely redundant to other system components, and much less immediate given the protected nature of these components upon the majority of installs, and just about universal where it pertains to marine installations. The manual concludes with considerations related to Headset and Belt Station storage, including notes on battery management.
This CMM is not intended to replace otherwise related best practices in use and care of like components subject to harsh environments. It is meant solely as a baseline of practices relating a combination of tested methods and common sense. The regularity of these steps should be determined based on use and exposure, and a reasonable schedule be established and adhered to, so as to not let any environmental residue build up to the point of difficulty of removal.
Please consult DCCI (Customer Service phone #: 508-751-5800, email:
service@davidclark.com) before using alternative materials, solvents, or otherwise questionable
practices in the maintenance of Series 9100 system components.

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. Push the headband down until the headpad (headband) rests comfortably on top of your head. Move the earcups slightly up or down or from side to side until you feel you have maximum attenuation (See Figure 1)
