| Just the power supply schematic would help, it appears to be a multi-rail outputtype, switched mode, running from 12 volts input with a 12 v output to charge the internal battery.
The only numbers on the pcb are OCD0214, means nothing to me though, Google has not helped either. Anyone have a clue? Regards Ffr |

|
| Hi
I have just obtained a Promax MC-944 satellite / tv&FM spectrum analyser, It has a fault in that on power up it always displays low batt 5.5volts and then shuts down, I need to find a service manual or schematics for the thing, anyone help. I have emailed Promax, but as yet heard nothing in two weeks. Any help appreciated please. Regards FFr |
