Do not carry the calculator around in your back pocket, as
it may break when you sit down. The display is made of
glass and is particularly fragile.
Keep the calculator away from extreme heat such as on a
car dashboard or near a heater, and avoid exposing it to
excessively humid or dusty environments.
Since this product is not waterproof, do not use it or store
it where fluids, for example water, can splash onto it.
Raindrops, water spray, juice, coffee, steam, perspiration,
etc. will also cause malfunction.

ber is in powers of 10.

Improper handling of batteries can cause electrolyte leakage
or explosion. Be sure to observe the following handling rules:
Replace both batteries at the same time.
Do not mix new and old batteries.
Make sure the new batteries are the correct type.
When installing, orient each battery correctly as indicated in
the calculator.
The factory-installed batteries may be exhausted before
they reach the service life stated in the specifications.

ranges, or if a mathematically illegal operation is attempted. If
an error occurs, pressing < (or >) automatically moves
the cursor back to the place in the equation where the error
occurred. Edit the equation or press N to clear the equa-
