## **HANDLING INSTRUCTIONS** SS ## **Mounting:** (1) Soldering on the body of the cylinder type crystal unit must be strictly avoided due to deteriorate the characteristics or damage the products. 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. **ATTENTION:** Abracon Corporation’s products are COTS – Commercial-Off-The-Shelf products; suitable for Commercial, Industrial and, where designated, Automotive Applications.
