Can I use an Uninterruptable Power Supply (UPS) to retain the programming?
Some VCRs do not have much of a long term memory should there be a power failure. Can a UPS designed for a computer system be used with these VCRs so that all the programming (and possibly channel settings as well) are not lost every time the power line burps? A UPS might be a solution but there are some issues to keep in mind: • If your VCR uses a switching power supply (with no input power transformer), it may be fine as the waveform does not matter that much. If it uses a power transformer, then there could be problems if the waveform put out by the UPS is far from sinusoidal – which it likely is. • The VCR is a very light load. I don’t know if this could be a problem with some UPSs. • The inverter in a typical UPS may generate Radio Frequency Interference (RFI) but this probably doesn’t matter if it only runs when the power fails and you aren’t viewing or recording at the time. If your VCR recently developed this amnesia, then you might consider attempting to locate the cause (a sh
