I exchanged for a new article for the first time in 25 years. At one point I thought of asking the electric shop, but if I looked closely well, I understood what I could and purchased. As a result of using it, the timbre of the chime was also good, it revived. However, I would like to have a camera next time next time. that's all
I wanted to obtain what I was using before it broke, but the successor model of the same manufacturer did not sell at the home center, so it was saved because I received it the next day. I was stuck with the successor model because I thought that there was little change in the hole position etc, so it was good that the change was actually small.
