USB Power Input (Figure 2).
Lift the rubber tab on the back of the WR-334-U to expose the power switch, as shown in Figure 2.
Select the Lithium Ion battery switch position:
Connect the DC power input cable (Figure 3) to the USB mini jack, and the other end to the USB
power source. The red battery charge indicator light will illuminate when charging (Figure 2).
Continue to charge the WR-334-U for several hours or until the charging light turns from red to green.
The WR-334-U is now ready for use.
NOTE:
Use 5.0V USB power source (from a computer or appropriate AC or DC adaptor).
Over-voltage may result in damaging the WR-334-U.

Solar Power
Lift the rubber tab on the back of the WR-334-U to expose the power switch, as shown in Figure 2.
Select the Lithium Ion battery switch position:
Place the WR-334-U in direct (or indirect) sunlight with the solar panel facing upwards. The green
battery charging light may illuminate when charging, as shown in Figure 1.
NOTE:
There is not enough solar energy to turn on the red charging light. Thus, no light or a faint
green 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.
