The paged individual lifts the handset of a Page/Party® station for two-way communication over the party line. Multi-Party: First, select an available party line using the five-position selector switch. [. . . ] Use a small standard screwdriver to adjust the receiver volume control on the rear of the amplifier using the extension ribbon cable assembly as described above. Adjust the receiver sidetone on the rear of the amplifier using the ribbon cable assembly as described above. Use the muting feature in the amplifier enclosure at the terminal blocks. Adjust the receiver sidetone at the amplifier, using the extension ribbon cable as described above. Check that the line balance assembly resistors are connected properly. Visually inspect the system cable connections for accidental crossing of the cable pairs or grounds. Incoming conversation level requires adjustment. Feedback/distortion (a hum or buzz on the line) occurs during all Page/Party® station operation. Feedback occurs only during page. Sidetone (how the operator hears his own voice) requires adjustment. Crosstalk occurs. f:\standard ioms - current release\42004 instr. manuals\42004-365b. doc 11/10 Model 701-305 Handset/Speaker Amplifier Pub. 42004-365B Page: 5 of 6 Specifications Amplifier Power requirements Voltage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 90­140 V ac range, 50/60 Hz, 120 V ac nominal Power consumed: Zero/max. 10. 5 VA, 5. 3 W/58 VA, 29. 5 W Construction/Finish. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 16-gauge cold-rolled steel/gray baked enamel Handset Microphone. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
