I am also Siemens APT, the previous LOGO is APT, next to a red circle, the center of a left turn 90 ° right angle, the previous meeting said it was 8.9 o'clock? The sun, now LOGO or not changed, but the manufacturer has changed, is the Shanghai branch of Suzhou Siemens Electric Co., Ltd. and Tiantai branch of the two, before the two work is wholly owned by Suzhou Siemens. But now all the products above did not play SIEMENS labeling, because that is very expensive,,, huh, do not know how to explain.
