4. Initialisation
To programme the CRU, depress the reset switch, SW4(S1 in early versions),
in the AC PSU for approximately 3 seconds. LED D8(D1 in early versions) will
begin flashing to indicate the CRU initialising and self test sequence. After
approximately 10sec, the CRU initialising and self test sequence will be
complete and the LED will be extinguished. LED D9(D1 in early versions)
will still be illuminated.
Should the above sequence not be successfully executed, replace the faulty
CRU.
