(*) A dot matrix display is located near the top of each universal card. Each display indicates the
channel number assigned to the Universal Card. The C&F card is indicated as 0. The other
universal cards are indicated from 1 to N, according to the card number assigned. The card
number will be displayed on the transmitting universal cards attached to the modulators, and on
the receiving universal cards attached to the demodulators.
System initialization phases are indicated on the C&F card dot matrix display. This display is
detailed in WMTS Digital Display and LED Indications on page 3.
