OPERATION INTRODUCTION Congratulations on choosing this Clear-Com product. Clear-Com was established in 1968 and remains the market leader in providing intercoms for entertainment, broadcast and industrial applications. The ruggedness and high build-quality of Clear-Com products defines the industry standard. In fact, many of our original beltpacks and main stations are still in daily use around the world.
Although the optional EB7-TW daughter board module allows this unit to function on a TW line, the unit’s operation will remain single channel. Also, the EB7-4W four-wire daughter board module is available to allow long-distance connections using separate pairs of wires for send audio and receive audio. The KB-701 is compatible with all Clear-Com party-line intercoms. OPERATION Normal operation of the KB-701 speaker station only requires access to the front-panel controls.
2. Call Button: Pressing the call button sends a call signal on the intercom line and causes all the call lights on other stations on the intercom channel to light. The call button lights red when a call signal is sent or received on the intercom line. 3. Speaker: The audio output for the KB-701 device. 4. Volume 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. 5.
7. Call Alert Tone Level Control: This internal control adjusts the volume of the call alert tone sound. This is normally adjusted when the system is set up and shouldn’t need to be adjusted during normal operation. This feature can be disabled by turning the control fully counterclockwise. 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-701 indicator panel.
• The default position of these switches is in the off position for normal mode, which is the only mode in which the call alert tone functions operate. In other modes, the call alert tone is automatically disabled to avoid interference with operation. Note: Only normal mode may be used when the EB7-4W four-wire option module is installed. 10. Intercom Line Connection: The KB-701 contains a five-terminal, plug-on connector for intercom line connection.

Option Board Jumpers: The two jumper plugs P1 and P3 must be installed when optional modules are not used. When the optional EB7-4W or EB7-TW modules are used, both P1 and P3 must be removed. Save these jumper plugs for possible future use. Note: 1-6 The KB-701 will not operate without either the jumper plugs or the optional modules installed.
INSTALLATION 1. Unpack the unit and inspect it for any damage that may have occurred during shipping. 2. Set the option switches to the default (toward the front panel) position. 3. Connect the intercom lines. 4. Install the KB-701 into the four-gang outlet box or V-Box. (For additional information, refer to the Clear-Com System Installation Manual.) 5. Set listen levels. (Refer to “Intercom Level Control.”) 6. The speaker station should now be operating properly.
