facing upwards. The green battery charging light may illuminate when charging, as shown in reference
21 in Figure 2.
NOTE: There is not enough solar energy to tum on the yellow charging light. Thus, no light or a
faint yellow light (which consumes less energy) may be present during solar charging.
NOTE: If the display heats up outside the operational range, the display will fade. For solar charging,
partial sunlight or shade is sufficient.
4.3 Hand Crank Power
To operate the hand crank, perform the following:
IMPORTANT NOTE: Disconnect the smart phone or PDA first from the USB charging port first
before cranking (the crank charges the internal battery and by design, the smart device must be
disconnected first to prevent the phone from power cycling and reduce the load on the crank).
1. Lift the hand crank from the cradle, as shown in Figure 2.
2. Tum the hand crank either clockwise or counterclockwise at about two cranks per second for
two minutes to activate the internal battery for initial use, or when the unit has not been used
for more than 60 days. The yellow battery charging light illuminates when charging, as
shown in Figure l. Aft er two minutes, rest for two minutes to extend the life of the hand
