Hold the body of crystal unit by hand, and the part to be bent with tweezers leaving more than 1.5mm of lead from the body case. (3.0mm is recommended) Rubber adhesive is recommended for mounting. Bend the lead 90°holding with the tweezers. Pulling the lead strongly may crack the hermetic seal glass at the root of the lead and may cause the airtightness and the characteristics to deteriorate. Product specifications are subject to change without notice. http://cfd.citizen.co.jp/english/prod-tech/product/cvo_top.html Rev.2
