Never use the CARRY-CODER II without a 50 Ohms load or antenna properly connected to the RF output, since this
could damage the RF output stage.

The system can operate with several COFDM signals located on 8 MHz adjacent channels. When analog
transmissions are active in-band it is recommended to leave a free 8 MHz channel between COFDM signals and the
active analog signals.

Power Supply Input
The CARRY-CODER II can be powered either with a battery pack or through the 4 pin connector. This enables the use of an
external power source such as a battery belt or any appropriate power supply (+11 to 32 VDC @ 4A).
