The control unit can be attached or disconnected at any time. Easily readable four line display. Operator navigation of menu with four intuitive directional buttons. Operational command entry using the button. Display includes status icons at right portion of top line. Text menu line one displays operating frequency.
CARRY-CODER II Transmitter Operating Mode Configuration NOTE: Most users will operate the system in mode. The mode provides user control of certain DVB-T parameter settings.
4965.00 MHz FREQUENCY 4965.00 MHz NO VIDEO When the CARRY-CODER starts up, it is in the same condition as when it was powered down. This allows the user to replace the battery with no need to touch the controls. The CARRY-CODER II will not transmit with out video. If the System is powered up without video, the CARRYCODER II will automatically reboot once video input starts. The CARRY-CODER II will transmit with ASI.
