Orientation and static care when rebuilding the battery area
The ICs, diodes, transistors, the tantalum capacitor and the zener can be killed by static you cannot feel, so ground yourself before handling them. Z1-Z4, Z36, C36, CR1-CR8, CR33-CR35, Q1-Q4 and VR1 fit only one way: copy the original board or the layout drawing, and line up each socket's pin 1 mark with the chip.
