Rubber adhesive is recommended. (2) When the leads need to be bent by hand, follow the instructions below. - Hold the body of the Cylinder type crystal unit in fingers. - Pick at the part with tweezers, which you intend to bend. There should be more than 1.5mm (3.0mm is recommendable) from the body case. - Bend the lead 90º by tweezers without pulling the lead strongly. Pulling the leads forcefully may cause cracks in the glass hermetic seal resulting in component failure.
