I have a RS-4i stimulator for back pain and my unit is saying to call for
servicing. The last time this happened I called the company and they
walked me through a sequence of codes to put into my machine and it was
ready to go. I now have the same message to call for service and Rs
medical is closed until Monday and I need to use my machine now. Does
anyone know how to reset it or know the reset code?

Please post how the codes work since I know you enter the program by holding the CH4 button down but then what new code do you enter???

I installed a new printhead for my laserjet hp L7580. It keeps giving me the message that the ink is empty, even though the cartridge is new, and the cartridge slot is clean like new.
