TIME_OUT_TIMER

Prevents unnecessary repeater timeouts by generating warning tone in loudspeaker of mobile transceiver when transmitter is on too long. Normal push-to-talk line is broken and connected to points A and D. Pushing talk button starts timer. Time in seconds is 1.1 R3C3, with R3 in megohms and 03 in microfarads. Thus, 1 megohm and 27μF give 30 s, while 2 megohms and 81μF give 180 s.-J. A. Kvochick, Keeping the Wind Down, 73 Magazine, Feb. 1977, p 50.
