(3)本机芯CPU为三洋公司设计的新型CPU,该CPU无专门的字符振荡外接LC网络,所需频率是通过对CPU时钟振荡晶体频率分频而得。所以在检修无字符故障时,要怀疑到CPU时钟振荡电路出故障。
(3) The movement The CPU is a new type of CPU designed by SANYO Corporation. The CPU has no special character oscillation external LC network. The required frequency is obtained by dividing the frequency of the crystal oscillation of the CPU clock. Therefore, in the maintenance of character-free failure, to suspect CPU clock oscillation circuit failure.
