Charging Temperature
Charge batteries in temperatures from 0 °C to 40 °C (32 °F to 104 °F). The device or cradle always performs
battery charging in a safe and intelligent manner. At higher temperatures (e.g. approximately +37 °C (+98 °F)) the
device or cradle may for small periods of time alternately enable and disable battery charging to keep the battery at
acceptable temperatures. The device and cradle indicates when charging is disabled due to abnormal
temperatures via its LED.
USB/Ethernet Communication
The 2–Slot USB/Ethernet Cradle provides both Ethernet communication with a network and USB communication
with a host computer. Prior to using the cradle for Ethernet or USB communication. Ensure that the switch on the
USB/Ethernet module is set properly.
Turn the cradle over to view the module.

activity, or stays lit to indicate that a link is established. When it is not lit it indicates that there is no link.
