OPTIONAL FEATURE OPERATION
The actual switch operations for the Single, Dual, and Triple Audio configurations were explained earlier in this
section of the manual, and should be used as required. The operation of each optional feature is similar, regardless
of the system configuration, and the differences will be explained for each option. The LED associated with each
switch and its operation depends on user requirements and system configuration. The color of the LED corresponds
to the channel used to play the tone or message. The following optional features are available for the 4100:
• Drill
• All Clear
• Aux Functions
• Phone Paging
• Manual Audio Override
• All Speakers Minus.
The operation of each of these features is explained in the following paragraphs.
