半导体收音机,最忌乱拨乱拧机内可调元件,如磁心,可变电阻、线圈等,一旦调乱,声音变小变杂;一旦调坏,更换元器件极易破坏原机指标。黑白电视机,最忌频繁开关电源,开一次电源,大电流就会冲击一次显像管灯丝,促使显像管进一步老化。彩色电视机,最忌强磁物体接近,彩色显像管一旦被强磁磁化,就会导致色彩紊乱。录音机,最忌按键过猛,不管录音机带仓是否关严,录音带盒是否到位,就使劲按功能健,结果往往会损坏录音机的一些部件。
Semiconductor radio, the most fierce indiscriminate mess screw machine adjustable components, such as the core, variable resistance, coil, etc., once the disorder, the sound becomes smaller and more mixed; once tune bad, replace the components easily destroy the original machine index. Black and white TV, the most avoid frequent switching power supply, open a power supply, high current will impact a tube filament, prompting the tube further aging. Color TV, the most hanged magnetic close to the object, once the color picture tube magnetization, it will lead to color disorders.
