The TI-Nspire™ Navigator™ wireless cradles contain rechargeable batteries. You must charge the batteries overnight before using them in class. When the cradles are fully charged, they will function all day under continuous use. You should recharge them each night.
The TI-Nspire™ Navigator™ Cradle Charging Bay can hold from one to five cradles. After you place the cradles in the charging bay, they are charged simultaneously until all are fully charged. If the batteries are fully discharged, it may take up to 12 hours to fully charge the batteries.
Note: You cannot damage the batteries by leaving them in the charging bay beyond the time needed to fully charge them. Also, it is not necessary to fully discharge the batteries before recharging them.
Make sure you have enough (3 to 4) power outlets for the equipment you received. If necessary, obtain a power strip so that you have plenty of grounded outlets.
