5.1.12 Media Module Cover, Main PCB, and WLAN PCB
CAUTION: Before accessing the main PCB, make sure that the power cord is unplugged from the
electrical outlet and the telephone line
is disconnected; otherwise, an electric shock could occur.
CAUTION: At the time of removal of the main PCB, untightening screws should be preceded by
disconnection of the harnesses and flat cables, and at the time of installation, connection of the
harnesses and flat cables, by tightening of screws. Observing this sequence prevents harnesses and
flat cables from getting crushed or damaged by screws or screwdrivers.
(1) Remove the media module cover towards you.
(2) Remove three screws "b1" through "b3" from the main PCB shield and lift it up.
"b1" and "b3": Taptite, cup B M3x8
