The batteries in
the network hubs
run down during
class time,
resulting in dead
or low batteries.
• Make sure the network hubs are recharged
overnight every night.
• Normally, the network hubs’ rechargable
batteries can be recharged and used for up to
three years. If you charge a battery overnight
and the LED on the network hub still blinks
red or amber, contact Texas Instruments for
help.
