1. After replacing the power IC or regulator transistor, apply a sufficient quantity of compound grease (RFKX0002/SZZ0L15) between the heat
sink and the power IC or regulator transistor (Radiation of power !C).
2. Tighten enough the screws. Otherwise, the heat radiation works little.
3. When installing or removing the power IC or transistor holder, be sure to use an offset screwdriver.
Along straight screwdriver cannot be used for removing or mounting the screws since its long grip interferes with the neighbouring P.C.B.
(See Fig. 1) :
А short straight screwdriver may be used for removal, but cannot be used for mounting because the limited space in the unit will not allow
sufficienttightening torque.(See Fig.2)

thermal breakdown.
