For a single calculation the calculation error is ± 1 at
the 10th digit (for the exponential display the
calculation error is ± 1 at the lowest value digit). The
errors' sum increases as the calculations continue
and may therefore become large (this also applies to
internal, continuous calculations, e.g. in the case of
^(
x
y
),
y, x
!, ,
n
Pr,
n
Cr, etc.). Close to the single
point of a function, and the point of inclection, the
errors' sum may become large.
CARE AND MAINTENANCE
Do not use harsh or abrasive cleaners or pads on the
calculator. A soft, dry or damp (with water) cloth
may be used to clean the calculator. Store the
calculator in a cool, dry place.
BATTERIES
This calculator is powered by two AA batteries. Clean
the battery contacts and thos of the device prior to
installation. Remove the batteries when not using
the product for an extended period.
Install batteries as indicated by the (+/-) polarity
signs. Remove empty batteries and/or batteries
which have not been used for an extended period
of time. Never use different types of batteries. Never
recharge non-rechargeable batteries. Never dispose
of batteries into a fire. These actions may cause the
batteries to explode. Do not throw away batteries;
dispose of as small chemical waste.
THE ENVIRONMENT
When this product reaches the end of its useful life,
hand it in at a collection point for the recycling of
electric and electronic equipment. Please refer to
the symbols on the product, the users instructions
or the packaging. Contact your municipality for the
