1.1.2 Unbending the lead
(1) DO NOT pull the lead excessively if unbending a lead or removing a crystal unit. The excessive force may
crack the glass and reduce the degree of vacuum. This may eventually result in deterioration of the
characteristics and may also break the crystal chip see Figure 3).
(2) Unbend the lead by pressing on the bent part from both the upper and lower sides with fixing the bottom of
lead tightly. (see Figure 4).
