The optional EB7-TW daughter board module can be installed to provide an 
interface to two intercom channels on a single microphone cable. Also, the 
EB7-4W four-wire daughter board module is available to allow long-distance 
connections using separate pairs of wire for send audio and receive audio. The 
EB7-4W four-wire option supports two-channel operation.
The KB-702 and KB-702GM are compatible with all Clear-Com party-line 
intercoms.
OPERATION
Normal operation of the KB-702 speaker station requires access only to the front 
panel controls. The controls located elsewhere on the unit are intended to be 
set-and-forget in nature. For intercom operation, set the listen level control to the 
desired level and press the talk button when talking. If a headset or handset is 
used, set the sidetone control for each channel for the desired amount of sidetone 
in the earphone. If a hand-held push-to-talk mic is used, or if the panel mic is 
used on the KB-702GM, set the sidetone controls for minimum feed-through to 
the speaker to prevent acoustic feedback.
FRONT PANEL
The controls, indicators, and connectors found on the KB-702 and KB-702GM 
front panels are shown in the following figures and are described by the following 
text. The numbers in the left column refer to Figure 1-1 and Figure 1-2.
