| 若新密碼無法使用,可能是數據未更新。請使用舊密碼看看。 A quick solution is to connect the terminal P.3.7 to the anode of the RS1 MCR100. Need to add in a diode.
(P.3.7 接到 MCR100 的陽極, 建議另加一個 DIODE (p 接到P.3.7), 再接上 MCR100 的陽極)
P3.7 ----> p/n diode ---> anode of MCR100
When the SCR is triggered, it will conduct for half of the period, and the P.7 terminal will be grounded. Once this happens, the speaker will receive current and produce an audio output. ... |
