Servicing
The SEM X6 circuit is designed and manufactured with the utmost care and
attention. However, a problem can eventually require a circuit replacement.
If this should happen, you will greatly appreciate this unique feature. The
entire memory of the X6 circuit, including the entire audit and all the different
settings are stored in a small 8-pin removable chip you can move to the new
X6 circuit. No need to reprogram all the settings in the new circuit board and
no loss of information on sales. That chip is located at the top right corner of
the circuit, next to the square blue LCD adjustment potentiometer above the
black button.
It is important to insert the chip carefully in the proper position. There is a
half-moon shape guide on the chip itself as seen below. This guide must be
opposite to the square blue LCD adjustment potentiometer.
This must be
achieved WITHOUT POWER on the circuit otherwise you will damage
the chip and loose the information it holds.
