KB-212 Speaker Station
2—Talk Lamp
The Talk lamp lights when the microphone feed to the intercom channel is on,
whether this is activated locally by the Talk button or remotely from another
station using the call signal.
3—Call Button
Pressing the Call button will send a call signal and cause all the call lights on
other stations on the intercom channel to light.
4—Call Lamp
The Call lamp will light while the Call button is pressed, or when a call signal
is on the intercom channel.
5—Tone Alert
An audible tone alert can sound when a call signal is received on the intercom
channel. This can be useful when the operator's attention has been drawn
away from the KB-212 indicator panel. The audible tone alert level can be
adjusted or turned off by an internal control. The Tone Alert will not sound if a
call signal is originated at the KB-212 station.
Note: This feature is automatically turned off if the operating mode of the KB-
212 is set to any setting other than Normal.
6—Intercom Level Control
Turn this control to set the speaker's required listen level. This control does
not affect the Tone Alert level or the Program Input level.
7—Program Level Control
Adjust the Program Level control to set the program audio level heard in the
panel speaker.
Note: Forcing the trimpots past their stop points will damage them.
8—Integral Microphone
The microphone for the KB-212 is built into the front panel.

Internal Adjustments and Connections

The controls and connectors inside the KB-212 are shown in the following
figure and described by the following text. The controls can be accessed
without completely removing the panel from its wall box or V-Box enclosure
by removing the top two screws and loosening the bottom two screws a few
turns. The panel can then be leaned out from the wall to make the controls
accessible as shown in the lower view of Figure 2 on page 5.
