lator Transistor (Q2022)
•
Refer to “Disassembly of Main P.C.B.”.
11.12.1. Disassembly of Voltage Regulator
Transistor
(Q2022)
Step 1
Desolder pins of the Voltage Regulator Transistor
(Q2022) on the solder side of Main P.C.B..
Step 2
Remove 1 screw.
Step 3
Remove the Voltage Regulator Transistor (Q2022) from
the Main P.C.B..
Caution: Avoid touching the Heatsink due to its high tem-
perature after prolong use. Touching it may lead to inju-
ries.
11.12.2. Assembly of Voltage Regulator
Transistor (Q2022)
Step 1
Apply grease to the Heatsink.
Step 2
Fix the Voltage Regulator Transistor (Q2022) on Main
P.C.B..
Caution: Ensure pins of the Voltage Regulator Transistor
(Q2022) are properly seated on Main P.C.B..
Step 3
Screw the Voltage Regulator Transistor (Q2022) to the
Heatsink.
Caution: Ensure the Voltage Regulator Transistor (Q2022)
is tightly screwed to the Heatsink.
Step 4
Solder pins of the Voltage Regulator Transistor (Q2022)
on the solder side of Main P.C.B..
