1. Talk Button and Indicator: The talk button activates the microphone feed
to the selected intercom channel. It has a dual action (momentary or latching)
depending upon how the button is pressed. If desired, the latching function
can be defeated using an internal option switch. The following describes the
various functions of this button.
• MOMENTARY: Press and hold the talk button while you are speaking.
Release it when you are finished. The button lights amber when the talk
function is active and blue when it is inactive.
• LATCHING: Press the button quickly to latch the talk function. Press
the button again to turn off the talk function.
• VOX INDICATION: On the KB-702GM, when the VOX feature is
enabled, the talk button illuminates amber to indicate an active talk, and
the VOX light illuminates amber to indicate that the panel microphone
is in use. This will automatically dip the speaker.
2. Call Button and Light: Pressing the call button will send a call signal on the
selected channel. All the call lights on that channel will then flash. Call
signals can also be sent while talking if required. The call button will light
when pressed, or whenever a call signal is present on the selected channel. An
internal option jumper can be set to allow the call button to light when a call
signal is present on either channel.
3. Tone Alert: An audible tone alert can be enabled to sound when a call signal
is received on the selected channel or either channel. This can be useful when
the operator’s attention has been drawn away from the KB-702 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 originates at the
KB-702 station or if the speaker on/off switch is turned off. The tone alert
