WARNING
Changing the above parameters may adversely affect
the ability of the device to operate for extended periods under low
solar radiation conditions when used with addVANTAGE 3.x. Even
if you change them, addVANTAGE will not display the charts
accordingly: the current addVANTAGE version supports only 15-
minute data slots. Changing the storage parameter to lower than
60 or higher than 1500 will lead to a total data loss in
addVANTAGE 3.x. This warning does not apply to usage with
addVANTAGE 4.x Lite software.
