The following symptoms indicate a defective control unit. Before replacing the control unit, perform the Key unit test (Procedure M) to determine if control unit is faulty.

2-1 In connection with pads.

a)When touching the pads, a certain group of pads do not produce a signal.

b)When touching the pads, no pads produce a signal.

2-2 In connection with indicators

a)At a certain digit, all or some segments do not light up.

b)At a certain digit, brightness is low.

c)Only one indicator does not light.

d)The corresponding segments of all digits do not light up; or they continue to light up.

e)Wrong figure appears.

f)A certain group of indicators do not light up.
