WARNING Anti-static table mat large 1200x650x1.25mm
All ICs and many semiconductors are small 600x650x1.25mm
susceptible to electronic discharges (ESD). Anti-static wrist band '
Careless handling during repair can reduce lite Connection box (1 MOhm)
drastically. Extendible cable (to connect wrist band to conn. box)
When repairing, make sure that you care Connecting cable (to connect table mat to conn. box)
connected to the same potential as the mass ol Earth cable (to connect any product to met or box)
the set via a wrist wrap with resistance. Keep Complete kit ESDa (combining all above products)

components and tools also at this potential.
