I used the old model already for about 30 years but it finally broke down.
If it is confirmed that the cause is not the only part of the backup battery inside, it will be impossible for themselves. Newly purchased.
Although there is a new function, setup does not change almost, it is easy to understand and easy. Recommended to organize a weekly program.
