•
When the hand-held is switched off, it goes into a low-power, suspend state
but continues to draw a small amount of power from the battery. This
should not be an issue unless the unit is left in suspend state for more than a
week – in this case, the battery should be removed.
3.7.1 Storing Batteries
Long term battery storage is not recommended. If storage is necessary:
•
Always try to use a ‘first-in first-out’ approach to minimize storage time.
•
Lithium Ion batteries age much faster at elevated temperatures. Store batter-
ies at temperatures between 0˚ C and 20˚C.
•
Always charge batteries to at least 40 to 60% before storing them. Batteries
can be damaged by an over-discharge phenomenon that occurs when an
empty battery is stored for a long period of time such that the cell voltage
drops below a lower limit.
•
To minimize storage degradation, recharge stored batteries to 40 to 60%
every 4 or 6 months to prevent over-discharge damage.
•
A ‘never used’ Li-Ion battery that has been stored for 3 years may have
limited or no useful life remaining once put into service. Think of batteries
as perishable goods.
3.8 Uploading Data In A Docking Station
Important:
Review the documentation provided with the user application
installed in your WORKABOUT PRO before performing data
uploads.
The desktop docking station and quad docking station allows the WORKABOUT
PRO to link to an Ethernet network. They are typically used to upload transaction
data to a server computer when a radio link in not available.
Note: Refer to
“Chargers And Docking Stations”
on page 141 for more details.
