Everything seemed to work properly, and the calibrations</span><br><span>appeared to be correct. However, after turning the unit off and back on, it</span><br><span>reverted to its non-calibrated state. So I did it again, and this time, I</span><br><span>saved all of the settings using the NVSAVE function. Powering off and on</span><br><span>had the same result with the cal being lost, but running the NVRESTORE</span><br><span>program correctly re-establishes the cal settings, so I'm not wasting a</span><br><span>couple of hours to do another cal, but it still will not retain the settings</span><br><span>without power.</span><br><span></span><br><span>Normally, I would think that the NVRAM was bad. However, while it loses the</span><br><span>cal settings, all of the other settings (user presets, front panel recall,</span><br><span>etc) which are stored there are OK and aren't lost with power off. So, is</span><br><span>there a step or something that I'm missing? I've not encountered this</span><br><span>before, so I'm hoping that someone has the answer!</span><br><span></span><br><span>Thanks.</span><br><span></span><br><span>Don </span></blockquote><br><br><div>
