the bottom of Math Whiz.

the illustration inside the battery compartment.

• Batteries must be installed with the correct polarity.

• Only batteries of the same or equivalent type are to be

used.

• Alkaline batteries are preferable.

• Do not mix old and new batteries.

• Do not mix different types of batteries: alkaline,

standar

d (carbon zinc) or rechargeable (nickel-

cadmium) batteries.

• Do not use rechargeable batteries.

• The supply terminals must not be short-circuited.

• Non-rechargeable batteries are not to be recharged.

• Remove exhausted batteries from the unit.
