Update aging facilities
From Japan
On 2018-02-10 17:19:39
I bought it for renewal of the aging facilities of RKW 24-14 RF using about 13 years. Although it seems that performance and miniaturization are no problem compared with the old type, it is difficult to understand that it is necessary to wire special connector to attach extension function. I wanted it to have versatility that general users can handle.
