1.3.2.1 Power Source Selection
The board can be used in normal-power mode or low-power mode, selected using the
J4 and Low PWR jumpers. For the locations of these jumpers, refer to Figure 9 .
Note: The Low PWR jumper is hidden under the
expansion board, which must be removed in order to
change the jumper setting - there are two jumper
positions,
BAT and REG .
Note: If batteries are being used and the board is going
to be left in the idle state for a significant length of time,
the batteries should be removed in order to conserve
their power.
