Program Chip Replacement Steps:
1. Note that one end of the replacement chip has a small notch in the center.
NOTE:
Be certain
the chip is installed with this notch toward the TOP of the control
panel.
If chip is installed upside down, the LCD display will be blank when
power is turned ON, and the chip will be destroyed.
2. Replace the chip very carefully, making sure that all prongs fit into their proper
receptacles and that none of the prongs are bent or touching each other.
3. When you are certain that all prongs of the replacement chip are in their proper
receptacles, carefully press the chip firmly into place with finger or thumb and
continue pressing until chip is properly seated in PC board receptacle.
4. Carefully reinstall display/control panel into position in the hood of the Alpha
Fuzion Sauna Body Pod, being cautious not to pinch or crimp any harness wires
(See Section 7.20).
5. Replace three screws in appropriate holes in display/control panel and tighten
gently but firmly in a rotational pattern until all screws are snug.
DO NOT OVERTIGHTEN.
6. Plug unit into power supply, turn unit ON at main switch and test display/control
panel for proper function. Note that if the LCD display is blank, program chip was
likely installed upside down.
