Tips on Caring For Batteries

become weak.
• Do not drop, puncture, disassemble, mutilate or incinerate the bat-
teries.
• Recharge only batteries that are rechargeable, and then only as
directed in the manual.
• Do not leave batteries in hot locations.
• When storing the AlphaSmart 3000 for several months (like over the
summer), remove the batteries.

When connecting the AlphaSmart 3000 to a computer, do not connect the

will use the power available in the keyboard cable, even if no batteries are
installed.
The DC jack input will accept 7.5-9V DC with a minimum current rating of
200mA. Off-the-shelf AC adapters may be used at your own risk and should
be marked with the ratings as shown. The DC jack polarity is negative
