KCDU Configuration
The KCDU may have to be configured to control excessive loudness if the system is close to a CO
or installed behind a PBX telephone system. It does not have to be configured for anything else.
The decibel (dB) PAD switches, SW501 (CO1) and SW601 (CO2), control the loudness by
providing a 3 dB signal level drop to, or from, the PBX or CO when set to the PAD position. The
switch comes from the factory set at NOR (for normal) meaning no PAD loss.
KCDU Installation
1. If the system is located within one mile of the CO or PBX telephone system, set dB PAD
switches SW501 and SW601 to the PAD position.
2. Insert the KCDU into the appropriate slot in the Expansion KSU, per tables in
. Apply firm, even pressure to ensure proper mating of the connectors.
3. After installing the KCDU, gently pull the PCB outward. If the connectors are properly mated,
a slight resistance will be felt.
Note
If KCDU CO lines receive Caller ID, RCIU2 must be installed.
KCDU Programming

programming information. When running Program 03 for the KCDU slot(s), specify code 65 if the
KCDU does not support OCA or PDIU-DI telephones or code 66 if the KCDU supports OCA or
PDIU-DI telephones. Do not specify code 11, 61, 62, or 64.
