NOTES ON POWER CONSUMPTION:

Assuming the Local Port is unused, the Network port is inactive, and the LCD

display is inactive, the 3530 will enter 'sleep' mode if it is not currently executing

an ACCOL task.

The larger the ACCOL load, the longer it takes to execute, and the longer the unit

'stays awake'. Load functions should be scheduled to run only when needed. This

means using logical signals as flags to control execution. Load tasks should be

carefully partitioned to execute only when necessary, so that maximum 'sleep' time

is obtained, thereby reducing power consumption.
