2. Disassembly Procedures of the Main Unit
Remove the eight pan head screws on the lower unit to open the device. But the upper unit and
the lower unit can not be separated because there are signal cables between them. Therefore you
should be careful to avoid destroying the signal cables when disassembling the device. Remove
these signal cables that can be dismantled directly and move them out of the lower unit to
uncover the hidden signal cables. Then dismantle these hidden signal cables to separate the upper
and lower units.

Disassemble the upper unit in the following sequence: display screen assembly -> keyboard
assembly -> indicator assembly -> recorder casing -> upper casing.
Remove the four groups of fixing bars and the cross recessed pan head cap screws , and
then the display screen assembly can be dismantled from the upper casing ⑤. Remove the fifteen
cross recessed pan head self-tapping screws ①, and then the keyboard PCB ② and the silicone
keyboard ③ can be dismantled from the upper casing ⑤. Remove the two cross recessed pan
head self-tapping screws ①, and then the indicator board ⑦ and the indicator cover ⑥ can be
dismantled from the upper casing ⑤. Remove the screws connecting the upper casing and the
