Power Sources
The WR-335 can be powered from the following sources:
DC power from a USB power source, such as a computer
AC power by adding a USB to AC adaptor (included)
DC car charger by adding a USB to DC car adaptor (optional)
Solar power
Hand crank power
Three AAA batteries (optional)
NOTE
: There is a charging LED on the back of the ADVENTURER2 (Figure 2, reference 19). The
red LED light flashes during charging. When fully charged, the LED turns solid RED.
7.1
Best Practices for Charging
We recommend periodically charging the ADVENTURER2 completely through the WR-335 mini
USB power input port (from your computer, AC adaptor or optional DC converter) every few weeks.
Disconnect after fully charged to extend the battery life. Do not leave plugged into the charger
indefinitely.
The solar collector will not completely charge your unit and is intended to extend the existing battery
charge.
7.2
DC and AC Power
Prior to using the WR-335, we recommend you fully charge the rechargeable battery through the USB
Power Input (Figure 2). This may take up to four hours.
Connect the power input cable (Figure 3) to the USB mini jack, and the other end to the USB or AC
power source. The red battery charge indicator light will flash when charging (Figure 2, reference
19). Continue to charge the WR-335 for several hours or until the charging light turns solid red. The
WR-335 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-335.
7.3
Solar Power
Place the WR-335 in direct (or indirect) sunlight with the solar panel facing upwards. The red battery
charging will flash when charging, as shown in Figure 1.
NOTE:
If the display heats up outside the operational range, the display will fade, but it will not
damage the display.
NOTE:
The solar collector will not completely charge your unit and is intended to extend the existing
battery charge. The solar collector efficiency is significantly impacted by direct vs. indirect sunlight,
