    7-7. Power Supplies The T6MC controller operates from either an ac input supply between 110 and 120 Vac, or 220 and 240 Vac. Alternatively, the controller can be used with a dc input supply between 21.6 and 32 Vdc. When both ac and dc input supplies are connected, the controller continues to operate using the dc supply if the mains supply fails.

  • Page 37: Transmit Operation

    Audio is therefore routed to the parallel connected controllers, but no PTT signal is sent. Use of the Intercom facility does not inhibit the External PTT signal. The intercom cannot therefore be used when an External PTT signal is connected to the transmitter. Park Air T6MC Controller Page 5-3 Maintenance...
