** Storage at high temperatures for an extended period of time will decrease the life time of onboard components
including the internal battery.
NOTE:
Operation with extended temperature range:
The limiting factor for the operational temperature range of the unit is the temperature rating of the Li-Ion batteries.
When using the unit at extreme temperatures, STS recommends removing the batteries (see DOC 0595 Battery
Removal Instructions) allowing the unit to run within a wider temperature window. Please also refer to DOC 0595
for proper handling procedures of the circuit board
