e If the date is 01-01-93, the battery-backed-up memory is probably
functioning correctly. Go to page 1-32, ‘’To perform self tests,’’ to
continue troubleshooting.
2 Check the battery voltage.
a Set the power switch to off ( O ).
b Remove the screws on each side and across the bottom of cover
number 6.
c Pull out the assemblies attached to cover number 6 until the
battery on the Memory assembly is visible.
d Measure the voltage between the top of the battery and A42 TP18.
e If the voltage is 3 ±1 V, the A42 Memory assembly is probably
faulty.
f If the voltage is incorrect, replace the battery (A42 B100).
