Overview
The normal service mode has not changed greatly. It is still entered the
same way, but now the registration section is completely different. In this
section we will concentrate on the new registration system and how ad-
justments are done in the PJED Mode.
Normal Service Mode
Entering service mode on the RA-4 chassis is done exactly the same way
as in previous chassis. With the power OFF, press Display Channel 5

second of each other. After this is done, the following display will appear
on the screen over the picture with the letters in green.
