second step in operating the intercom mode. Once the station has been selected,
communications from the master station (RAY 430 unit) can be enabled.
In the intercom mode, upon pressing the microphone [PTT] button, “TALK” appears in
the speaker station display window. Your voice signal through the microphone is
amplified and sent to the Selected intercom speaker(s).
When the [PTT] button is released, the speaker at the selected station location can act as
a microphone, with sounds being heard at the RAY 430 internal speaker or external
speaker (if connected). The RAY 430 microphone takes priority over any responses
from intercom sub-stations. This means that the sub-stations cannot be heard if the
[PTT] key is held down.
Both the HAIL and LISTEN controls can be adjusted for desired volumes by rotating
the Hail or Listen volume control knobs.
Marking calls from Remote Intercom Stations
As long as RAY 430 power is on, the RAY 430 master station can be called from any of
the Inter-com sub-stations.
When the [CALL] switch on the sub-station speaker is pressed, both an audible beeping
and an LCD display indicator tell the master station which remote station wishes to
communicate with the master station. At the RAY 430 master station, the operator
would then select the intercom station key corresponding to the calling station and
speak into the microphone to communicate.
The RAY 430 allows you to connect a maximum of four intercom station speakers. The
remote intercom stations cannot communicate directly with each other.
