Possible Cause Checks Corrective Action
Switches open. On the Memory I/O PCB, at
least one switch position (1 or
2) on DIP switch S2 must be
closed. If both positions are open,
close S2-1. If the LED
remains lit, open S2-1 and
close S2-2.
Dead or shorted battery,
defective battery circuit. Measure the voltage at the test
points on the PCB. If one or
both of the battery voltages are
within range specified, one or
both batteries are okay;
perform corrective actions
listed. If possible, always back up
and poll all system data before
replacing the batteries or SC
III boards. On the memory
PCB, if S2-1 is closed, open
S2-1 then close S2-2. If S2-2
is closed, open S2-2 then
close S2-1. If the LED does
not remain lit, replace the bad
battery as soon as possible
(S2-1 connects battery B1 &
S2-2 connect battery B2). If
the LED remains lit, replace
SC III board C07077 set as
soon as possible.
Batteries not installed. Check B1 & B2 on C05839. Install needed batteries.
