X20 Console Manual
The X20 Console
The X20 has a power management system that remains active even
when the unit is switched OFF. However it uses very little standby
power, typically 600uA at 5V or 0.003W.
This management system ensures that before an X20 can be turned
on and used there is enough internal battery energy available to
successfully close the unit down in the event of the sudden and
unexpected loss of the external supply. This is designed to protect the
users data and also protect the integrity of the operating system and the
compact flash it is built on.
The internal battery is not there in order to use the X20 as a fully
mobile device and will not support this function.
Any voltage transients from vehicle start-up are also controlled by the
internal battery.
The battery packs are deep cycled at Topcon Precision Agriculture
before the X20 is dispatched.
