PowerChoice Manufacture Default Power Condition Timer Values
Default power condition timer values have been established to assure product reliability and data integrity. A
minimum timer value threshold of two minutes ensures the appropriate amount of background drive mainte-
nance activities occur. Attempting to set a timer values less than the specified minimum timer value threshold
will result in an aborted EPC "Set Power Condition Timer" subcommand.
Setting power condition timer values less than the manufacturer specified defaults or issuing the EPC "Go to
Power Condition" subcommand at a rate exceeding the default timers may limit this products reliability and
data integrity.
