GENERAL INFORMATION
Scope
This section provides detailed installation and interconnection instructions for the DT100 Analog
Telephone Handset. Please read this manual carefully before beginning any installation to prevent damage
and post installation problems. Installation of this equipment requires special knowledge and tools.
Installation Requirements
The DT100 requires specialized knowledge and tools for an effective installation. An appropriately rated
Certified Repair Station must install this equipment in accordance with applicable regulations. Deklin
Technologies, Inc warranty is not valid unless installed by an authorized FAA approved repair station.
Failure to follow any of the installation instructions, or installation by a non-certified individual or
agency, will void the warranty and may result in a non-airworthy installation.
Unpacking and Inspection
Use care when unpacking the equipment. Inspect the unit and all the parts supplied for visible signs of
shipping damage. Examine the unit for loose or broken pieces. Verify the correct quantity of components
supplied with the list in Section I. If any claim is to be made, save the shipping material and contact the
freight carrier. DO NOT return any items damaged in shipping to Deklin Technologies, Inc. If any items
show signs of external shipping damage, contact Deklin Technologies, Inc for a replacement. Do not
attempt to install a damaged unit. Equipment returned to Deklin Technologies, Inc for any other reason

INSTALLATION PROCEDURES
Cooling Requirements
Forced air-cooling is not required for the DT100. However, the equipment should be kept away from heat
sources without adequate cooling provided. (i.e. defrost or heating ducts, dropping resisters, heat
producing avionics.)
Mounting Requirements
The DT100 must be mounted inside the pressure vessel in a temperature controlled environment unless
the aircraft’s service ceiling is less than 25,000 feet.
The DT100 must be rigidly mounted to a secure structure in accordance with FAA Advisory Circular AC
43.13-2A. The unit should be mounted in an area with adequate clearance for the unit and associated
wiring.
The locking base must be firmly mounted using two 6/32 screws from behind the mounting surface into
the pem-nuts of the base. The drop-in cradle is mounted using two 8/32 screws through the base and
mounting surface into locking 8/32 nuts or fasteners.
Connector Assemblies
The curly cord assembly comes complete with 2 each RJ11/6 plugs on either end, or, an RJ11/6 on one
end and a 9-pin D-Sub connector on the other. It does not require additional assembly.
When using the locking base, the mating RJ11/6 jack or 9-pin D-Sub connector should be mounted in
close proximity to the base assembly so as not to cause any tension to the curly cord when the handset is
locked into the base assembly.
