The buzzer of the Master's phone broke the silence between the two men, a silence undertoned by the throb and hum of the now effectively operating engines. "Well, what is it?" the Master queried. "Promising oasis, mon capitaine," came the voice of Leclair from the upper starboard gallery. "Through my glass I can make out extensive date-palm groves, pomegranate orchards, and gardens.
See, also, that all of the connections are tight and where you have to cross the wires keep them apart by an inch or so and always cross them at right angles. Adjusting the No. 1 Set The Detector. The first thing to do is to test the detector in order to find out if the point of the contact wire is on a sensitive spot of the crystal. To do this you need a buzzer, a switch and a dry cell.
When you tune the transmitter so that the ammeter shows the largest amount of current surging in the aerial wire system you can consider that the oscillation circuits are in tune. General view of Power Room. The Buzzer and Dry Cell.
Before Craig had a chance to put another question, the buzzer on our door sounded, and I admitted a dapper, soft-spoken man of middle size, who might have been a travelling salesman or a bookkeeper. He pulled a card from his case and stood facing us, evidently in doubt how to proceed. "Professor Kennedy?" he asked at length, balancing the pasteboard between his fingers. "Yes," answered Craig.

A little later a knock came upon the door.
The Operation of the Key Circuit. The effect in a C. W. transmitter when a telegraph key is connected in series with a buzzer and a battery and these are shunted around the condenser in the grid circuit, is to rapidly change the wave form of the sustained oscillations, and hence, the length of the waves that are sent out.
It had orders to worry about Brion's health, so it did, checking constantly against its recorded instructions and noting his steady progress.

A light flashed and a buzzer hummed gently but insistently.
The night wore on, the orderlies slept and woke, stumbled in and out; the telephonists droned out in monotonous voices to the telephone, or "buzzed" even more monotonous strings of longs and shorts on the "buzzer."
