The batteries in
the wireless
cradles run down
during class time,
resulting in dead
or low batteries.
• Make sure the wireless cradles are recharged
overnight at least every other night. If your
system is used heavily during the day,
recharge the batteries every night.
• Normally, the wireless cradle’s rechargable
batteries can be recharged and used for up to
three years. If you charge a battery overnight
and the LED on the network cradle still blinks
red or amber, contact Texas Instruments for
help.

• Do not attempt to configure more than one
classroom network at the same time.
• Remove the handhelds from cradles that you
do not want to add to your network.
• Compare the cradle numbers listed in the
TI-Nspire™ Network Manager window with
the numbers stamped on the backs of the
cradles themselves. Highlight and remove any
cradles in the list that should not be part of
your network.
Data is received
by some
handhelds, but
not all.
• Make sure the TI-Nspire™ handheld is
securely connected to the TI-Nspire™
Navigator™ wireless cradles.
• Make sure all of the handhelds have the latest
operating system from Texas Instruments
installed.
• Make sure the handheld’s RAM is not
completely full.
• Make sure an alternate operating system,
such as Mirage, is not installed. If found,
remove it from the handheld.
The handheld
does not respond
in any way, and
appears to be
“locked up.”
• Reset the handheld. For instructions, refer to
the guidebook for the handheld.
