3.5.4 Connector PCB replacement
Lay the Connector PCB beside the CPU PCB so that the ribbon cable can be inserted,
make sure the latch on the ribbon cable socket is fully open, then insert the cable
fully and close the latch. The Connector PCB can then be folded over on top of the
CPU PCB – check the ribbon cable folds neatly between the two boards. Then screw
the Connector PCB into place using the T06 Torx screw [015] and washer [016].
3.5.5 AF PCB replacement
The AF PCB must be slid down the battery chassis [005] from the capsule end.
When the PCB reaches the ribbon cable carefully fold the cable so that it goes under
the AF PCB and the free end protrudes for connection after the T06 Torx screw
[013] is inserted. Reconnect the ribbon cable, first making sure the latch on the
ribbon cable socket is fully open, then insert the cable fully and
close
the latch.
3.5.6 Capsule replacement
The capsule replacement is straightforward but make sure that the connector pins
(opposite the screw socket) on the capsule are in correct alignment with the socket
in the unit – the alignment is correct when the pins on the capsule align with the
LCD display window. When replacing the basket make sure the coloured ring [002]
is replaced between the basket and the barrel.
3.5.7 Refit barrel over chassis
The chassis should be gently inserted PCB-end first into the wide-end of the barrel
until the battery compartment comes out of the other end and it stops.
3.5.8 End Cap replacement
Inside the end cap are guides to hold the PCB’s securely in place, and during
reassembly it is essential to make sure the boards are properly located. When the
rear cap is pushed almost fully home the USB connector, jack socket, and rotary
switch will emerge from the end of the rear cap – check these are correctly aligned,
and do not force the end cap into place. When replacing the three T08 Torx screws
[017] do NOT over tighten as this could strip the threads in the battery chassis
[005].
