ALL-CALL CONTROL:
Located underneath Master Station and so marked. All Call Control is easily
accessible with the index or forefinger of the right hand. When it is desired to call all Sub-Stations
simultaneously, place All Call Control in “on” position (toward front of unit). Upon completion of “All Call”,
return All Call Control to “off” position (toward rear of unit).
TRANSLUCENT INDICATOR:
Located to left and below volume control knob on Master Station.
Indicates that unit has power.
OPERATION OF MASTER STATIONS
These systems have been designed for use where one Central Location must communicate with other
locations, but these other locations need not communicate with one another. ONE AND ONLY ONE
MASTER STATION CAN BE USED IN EACH KB-ML-5 or KB-ML-10 SYSTEM.
In Moderate to Low Noise Level Areas,
use TALK-A-Phone Model K-LR-3 or K-LR-3W Sub-Stations.
For High Noise Level Areas, or In Very Large Locations,
use TALK-A-PHONE Models K-C-20(V) or K-
HP-3(V) in place of Models K-LR-3, (W) Sub-Stations. Models K-C-20(V) will supply more than 3 times
as much volume. Model K-HP-3(V) will furnish more than twice the volume. K-C-20(V) is a Re-Entrant
Horn and is more directional than the K-HP-3(V).
Depress the station selector switch corresponding to the Sub-Station you desire to communicate with.
When you want to communicate with all of the Sub-Stations at once, use the “All Call” Control. Under
“non-private” operation, when not communicating with any Sub-Station, leave the station selector
switches in the “off” position (raised up) and you avoid listening to sounds coming from Sub-Station
locations (Sub-Stations can still call the Master). Upon completion of each conversation, return station
selector switches to “off” position.
Depress the Talk-Listen Control as far as it will go and “talk”. Release the Talk-Listen Control and “listen”.
Then adjust the Volume Control until desired volume is obtained.
OPERATION OF SUB-STATIONS
When System Is “Non-Private”:
Sub-Station can answer the Master Station without any operation on
the part of the person at the Sub-Station, and at a distance from the Sub-Station. To originate a call from
a Sub-Station merely depress the Talk-Listen Control on the Sub-Station (use K-S-100(W) Origination-of-
call Switch with K-HP-3(V) and K-C-20(V), and give your station number. Once the person at the Master
Station has answered you, there is no further need to operate the switch on the Sub-Station while
carrying on a conversation.
When System Is “Private”:
Sub-Station can talk to the Master Station only when depressing the Talk-
Listen Control on the Sub-Station (use K-S-100(W) Origination-of-call Switch with K-HP-3(V) and K-C-
20(V). Therefore, the Master Station cannot listen-in on the Sub-Station.
Model K-HP-50 Power Booster can be added to the system at any time and connected to TALK-A-
PHONE paging speakers, as Models K-LR-2 (R), K-HP-3(V), K-C-20(V). Use of the K-HP-50 will provide
a one-way paging circuit whereby any Master Station can page, but persons at the paging speakers
cannot reply or originate calls. Connect the K-HP-50 to its own station number in the system.
Close proximity of the Sub-Stations to the Master Station may result in a howl (acoustical feedback) when
either one calls the other. Reduce the volume on the Master Station or keep them partitioned from each
other. The Master Station controls the volume of the system with these models.
