Hi,
I have this spectrum since 1992 but the batterie was installed in 1990. This is 18 years and I don't think the internal batterie had been change. It is mark on the back of the instrument that the batterie will last 8 years at room temperature. In the case of the batterie had failed, could that cause me the FREQ UNCAL problem because it can't hold anymore the calibration coefficients?

You need change the internal battery and then cal freq and ampl.
