The DCD LED - Data Carrier Detect
The DCD LED is an indicator of channel activity. When another station
transmits, the DCD LED on the PK-88 should light for the duration of the
received packet frame. If the DCD LED is lit by random noises, reduce your
receiver's output volume control until the LED goes out. Valid packets
received should always light the DCD LED.
