Memory Chip Installation
The memory chip for this system is packaged in a separate box and must be installed prior to
powering the system. Memory chips are static sensitive. Handle them with care! Never install the
memory chip with power applied to the controller.
1.
Remove the keypad mounting plate from the back box by removing the small screws
located in each corner.
2.
Locate the memory chip socket located on the back of the circuit board near the
bottom.
3.
IMPORTANT! Be sure power is OFF.
4.
Carefully remove the memory chip from its packaging and install it so that the small
indentation is pointed up. Be sure that all eight pins are properly seated in the
socket.
5.
Re-install the keypad mounting plate using the screws removed in step 1.
