Operation
The Page/Party ® station operator controls the Coupler’s connection to the page or party line by the off-
hook and page conditions.
• When all stations are on-hook, the Page/Party ® Radio Coupler is connected to the page line.
• When any station is off-hook on the designated party line, the Page/Party ® Radio Coupler is
connected to that party line.
• When the Page/Party ® station operator lifts the handset and presses the handset pressbar, the
Page/Party ® Radio Coupler is connected to the page line.
Call Originated by a Page/Party ® to a Radio Operator
For paging and subsequent party line conversation, the station operator lifts the handset, selects the
dedicated party line using the five-position rotary selector switch and presses the handset pressbar to
connect to the page line in the Radio Coupler. The station operator pages the desired individual. The
page is heard over Page/Party
® system and the radio frequency. After the page, the station operator
releases the pressbar to connect the station to the party line in the Radio Coupler. The radio operator
then responds by keying the radio and talking.
The resulting communication is half duplex, meaning the person currently talking has control of the
conversation. The other operator must wait until the first person has finished talking.
After the conversation is complete, the Page/Party ® operator should place the handset back on-hook.
