Charging the Handheld Device
To prevent corrosion, thoroughly dry the USB port, the weather cap, and the surrounding area before charging or connecting to a computer.
You should fully charge the battery before you use the device for the first time. Charging a fully depleted battery takes about 2 hours.
NOTE:
The device does not charge when it is outside the temperature range of 0° to 40°C (32° to 104°F).
The LCD display on the handheld device shows the current battery charge level. Charging is complete when the battery charge level icon stops flashing.
