05.01 TYPENUMBER(S): AJ3935
SYMPTOM : IRIS CODE 2 1 4 4
Transformer hum is audible.
CURE : The hum is caused by vibration of the metal transformer bracket (item
502). For service purpose the metal bracket can be removed without
substitution.
REMARKS : In production, a rubber foam of 20 x 25 x 26 mm will be placed
between top of transformer and Top Cabinet (item 427).
This will protect the printed board from being damaged during transit.
The modification has been implemented in production from week
0014 onwards.
