1)Remove the PCB from its protective packag- ing.

NOTE:

The dB PAD switches SW101 through SW401 control excessive loudness resulting from close proximity to the CO or PBX telephone office by providing a 3 decibel (dB) signal level drop to, or from, the PBX or CO when set to the 3 position. Switches are factory-set to the 0 (0 dB signal level drop) position.

2)If the Expansion Unit is located within one mile of the PBX or CO telephone office, set dB PAD switches SW101 through SW401 to the 3 (-3 dB signal level drop) position.

3)Insert the PCOU into the appropriate slot (refer to Paragraph 2.22), and apply firm, even pressure to ensure proper mating of connectors.

4)After installing the PCOU, gently pull the PCB outward. If the connectors are properly mated, a slight resistance will be felt.
