Charging TI-Nspire™ CX and TI-Nspire™ CX CAS handhelds

There are several options for charging your TI-Nspire™ handhelds:

•Connect to a computer using the supplied USB cable. (Requires TI-Nspire™

computer software or TI-Nspire™ Computer Link software be installed

before connecting.)

•TI-Nspire™ Wall Adapter (Contact your educational dealer)

•TI-Nspire™ Docking Station (Multiple handhelds)

Charging your TI-Nspire™ handheld using a computer

The TI-Nspire™ handheld can be charged from a computer. TI-Nspire™ software

must be installed prior to connecting the handheld to ensure the appropriate drivers

are installed. Power management controls on some computers may prevent

continuous charge via the USB port. Stand-by and sleep modes on laptop

computers typically terminate USB connectivity to conserve power. In some cases

this can be adjusted through the device manager:

•Install the TI-Nspire™ software before connecting the handheld to the

computer. If you do not have access to the TI-Nspire™ software, install the

TI-Nspire™ Computer Link software (Free).

•Once the software is installed connect your handheld to the computer using

the USB cable provided.

•Check the connectivity between the handheld and the computer. A simple

way to do this is using the screen capture tool in either the TI-Nspire™

software or the TI-Nspire™ Computer Link software.

Note: When capturing a screen from the handheld make sure the handheld is

connected and selected. (Shown opposite)

Another option for checking connectivity between the computer and handheld is the

Device Manager (Windows®) or System Profiler (Mac®). Locate and expand the

Universal Serial Bus controllers and select: TI-Nspire™ Handheld Device.

(Shown opposite)

•When the handheld is charging the battery icon on the top right corner of the

handheld screen will display a ‘charging’ symbol. (Shown opposite)

Note: Charging status on the handheld can be checked via the Settings option

on the home screen. Select Settings followed by Status to view the current level

of charge. The status screen is not automatically refreshed, return to the home

screen to refresh the charge status information.

Charging your TI-Nspire™ handhelds using the TI-Nspire™ Wall Adapter

The TI-Nspire™ Wall Adapter (not supplied) can be used to charge the TI-Nspire™

handhelds. The TI-Nspire™ Wall adapter provides a USB outlet and is connected to the

handheld via the USB computer-to-handheld cable.

Make sure the TI-Nspire™ Wall Adapter is designed for Australian mains supply.

Other wall adapters including those designed for overseas may not charge the handheld

or in extreme situations, damage the unit. (Warranty is void if the product is damaged

by an unapproved wall adapter.)

The TI-Nspire™ Wall Adapter s can be purchased from our educational dealers:

Charging your TI-Nspire™ handhelds using the TI-Nspire™ Docking Station

The TI-Nspire™ Docking Station is designed for classroom use where

multiple handhelds require charging. Information about charge and status

is displayed using a series of LEDs on the TI-Nspire™ Docking Station.

The TI-Nspire™ Docking Station must be connected to a mains

power supply.

The TI-Nspire™ Docking Station can also be used to send files to

multiple handhelds when connected to a computer with the TI-Nspire™ Teacher Edition software or

TI-Nspire™ Navigator™ software installed.

Charging Troubleshooting for TI-Nspire™ handhelds

The most common error when attempting to charge the TI Rechargeable Battery is via a computer.

Termination of power supply to the USB port due to the computer or computer settings prevents the

handheld unit from charging. Charging the TI-Nspire™ handheld for the first time takes between

4 and 6 hours, thereafter charge time depends largely on the status prior to

charging. If charging from a computer does not produce the desired result try:

•Using the approved TI-Nspire™ Wall Adapter

•Resetting the handheld device using the reset button on the reverse.

TI Rechargeable Battery maintenance for TI-Nspire™ handhelds

Lithium-ion batteries have a limited life, which is affected by several factors: environment, storage, the

number of charge/discharge cycles, and level of discharge/charge. To extend the TI Rechargeable

Battery lifespan and battery life, we recommend following these simple guidelines:

1. Avoid heat and humidity:

•TI Rechargeable Battery is designed to operate optimally at room temperature.

•Heat can reduce lithium-ion battery life.

•High humidity environments should be avoided.

2. Usage and Charging:

•As lithium-ion batteries age, they lose capacity. When properly maintained and under normal

usage, batteries are expected to last at least several years.

•If you use the TI-Nspire™ handheld regularly, recharge the TI Rechargeable Battery often.

Avoid waiting until it is fully discharged.

•If you do not use the TI-Nspire™ handheld regularly, fully recharge the TI Rechargeable

Battery at least once per month.

•Do not leave the TI-Nspire™ handheld connected to a charging device for longer than 3 days.

•Use only TI Rechargeable Battery approved for the TI-Nspire™ handhelds.

•Use only charging devices approved for the TI-Nspire™ handhelds.

3. Recommendations for storing TI-Nspire™ handhelds with lithium-ion TI Rechargeable Battery for

3 months or longer:

•The best temperature for proper care and storage of lithium-ion batteries is between 0–25°

•Extended storage can cause batteries to discharge deeply, which can deteriorate the lithium-

ion cell and reduce the TI Rechargeable Battery capacity, service life and ability to recharge.

It is recommended the TI Rechargeable Battery be fully charged before putting the handheld

in extended storage and that it be recharged fully every three months while in storage.

4. Update your TI-Nspire™ handheld Operating System (OS) as new updates become available. OS

updates may contain new programs to optimize TI Rechargeable Battery life.
