I have a 2001 Fleetwood Bounder RV with a Heart Interface Inverter.
This inverter uses modified sine wave technology which is not
compatible with all electrical devices. My current VCR experiences
audio interference when powered by the inverter. And the UPS battery
pack I purchased and returned would not charge via the inverter.

I wish to purchase a DVD/VCR player or just a VCR that will not
experience audio interference. And also a UPS battery backup device (a
small model used to backup a 42 watt device) to connect to my
satellite receiver. I need to know the brand and model numbers of
these two devices that will work with the inverter.

Thank You,
Cathy Baker
