    A remedial action is to vary the scramble and pscramble options and then retry. If it is necessary to connect the transmit port of the DAG 4.3S to other equipment, it is necessary to enable the transmit laser. The laser normally used is eye safe, but is disabled as a precaution as it is not normally needed.
