TN100 System Installation and Troubleshooting

MT-3 Radio Systems

MT-3 Subrack

Ensure that the MT-3 Application Specific Manual is included with your system. This manual con-

tains information specific to the configuration of the radio system. It includes test sheets for each trans-
mitter, receiver and power amplifier, audio control card jumper lists, detailed instruction sheets for
CTCSS and DTMF modules if purchased, and other specific information. Each custom sheet should
have an Application number (Axxxx-xx) associated with that custom jumper setting, wiring, etc., as well
as a Block diagram (Bxxxx-xx). Please use this number in any future orders for identical systems.

NOTE: If ordered as a system, instruction manuals for each module (subrack, system monitor, receiver,
transmitter, etc.) are typically included with the equipment.

Ensure the main rack has enough room for the Daniels subrack to be installed. Each Daniels subrack

requires 5 1/4” height (3 RU) and 13.5” (maximum) depth clearances.

Install the EIA standard 19" subrack units in main rack using four #10 x 3/4" screws. Use stainless

steel screws if the equipment is to be placed in a corrosive environment. If necessary, remove the han-
dles from the subrack to facilitate installation.

. Interconnect primary power (10 - 16 Vdc, 13.8 Vdc nominal) to the Barrier Strip power input on the

rear of the subrack (refer to drawing below). Use a wire gauge suitable for delivering the power required
by the subrack(s).
