checks highlighted by circled numbers, which are described in detail below:
(1) Place the tester probes across pins 1 and 2 of the HD4 connector of the receiver on CU611
cable. The measured value should be +5Vdc.
(2) As at step (1) but on pin 1 and 5 on CN24 connector of the Display Board.
(3) Check the correct display SW version, according to the “EXCITE SW SMART TABLE” you
can find in TG Direct ,“NEWS” section.
