CAUTION
AC power supply recovery after power failure does not automatically
start the battery recharge process until the ETERNUS2000 is also turned
on. As the contents of the cache memory will clear as soon as the bat-
tery is fully drained, the ETERNUS2000 must be turned on immediately
following AC power supply recovery, or the AUTO POWER switch may
be set to ON instead.
