USER STATION CONNECTIONS

Routing the TW Intercom System cables along the same

ductways and pathways as power cabling can increase the

noise and hum levels.

Moisture / Contamination Protection

When using equipment in the rain, always protect the equip-

ment with plastic covers----also, make sure all cable con-

nectors are lifted out of the mud or snow and protected with

plastic bags. Water, mud and snow in connectors can cause

considerable audible noise.

Hum Prevention

Prevent inducing hum into the system by not locating user

stations near hum sources such as power transformers, elec-

trical switch panels, lamp dimmers or TV cameras. When the

microphone switch is turned on, the dynamic microphone

acts as a sensitive antenna for hum sources.
