(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.
