一、松下NV—370录像机增设断电记忆该机属早期产品,无断电后备电源,当断电时它的记忆也消失。这时你所设置的定时录像时间也消失,当重新来电时,便不能录下你所设置的电视节目。经改动,可增设后备电源,完善这一功能。措施:将录像机上盖板打开,在通道预置板上可找到TP7508测试点,该点可作为备用电源的输入端,将6V干电池通过φ3.5mm插座(安装在机壳后适当的位置)引进机内,电池负极就近接地,电源正极通过所串接的两只硅二极管,使电压降为5V左右(如图1所示)。
First, the Panasonic NV-370 recorder additional power-off memory This machine is an early product, no power backup power supply, when the power is off its memory disappears. At this time you set the timer recording time disappears, when you call again, you can not record the TV show you set. After the change, additional backup power can be provided to improve this function. Action: Open the deck cover and find the TP7508 test point on the Channel Preset, which can be used as a backup power input to bring a 6V battery through the φ3.5mm socket (installed in the proper location on the chassis) Machine, the battery near the negative ground, the positive power supply through the series of two silicon diodes, the voltage dropped to about 5V (Figure 1).
