Handling Precautions
Be sure to press the button on the back of the
calculator before using it for the first time.
Even if the calculator is operating normally, replace
the battery at least once every three years. Dead
batteries can leak, causing damage to and malfunction
of the calculator. Never leave the dead battery in the
calculator.
The battery that comes with this unit discharges slightly
during shipment and storage. Because of this, it may
require replacement sooner than the normal expected
battery life.
Low battery power can cause memory contents to
become corrupted or lost completely. Always keep
written records of all important data.
Avoid use and storage in areas subject to temperature
extremes. Very low temperatures can cause slow display
response, total failure of the display, and shortening of
battery life. Also avoid leaving the calculator in direct
sunlight, near a window, near a heater or anywhere
else it might become exposed to very high temperature.
Heat can cause discoloration or deformation of the
calculator’s case, and damage to internal circuitry.
Avoid use and storage in areas subject to large amounts
of humidity and dust. Take care never to leave the
calculator where it might be splashed by water or
exposed to large amounts of humidity or dust. Such
elements can damage internal circuitry.

2
Never drop the calculator or otherwise subject it to
strong impact.
Never twist or bend the calculator. Avoid carrying the
calculator in the pocket of your trousers or other
tight-fitting clothing where it might be subjected to
twisting or bending.
Never try to take the calculator apart.
Never press the keys of the calculator with a ball-point
pen or other pointed object.
Use a soft, dry cloth to clean the exterior of the unit. If
the calculator becomes very dirty, wipe it off with a cloth
moistened in a weak solution of water and a mild neutral
household detergent. Wring out all excess moisture
before wiping the calculator. Never use thinner, benzene
or other volatile agents to clean the calculator. Doing so
can remove printed markings and damage the case.

such as sin, log, and all R P menu items.
3rd Fractions.
4th Functions that are entered after the argument, such
as x and angle unit modifiers ( r g).

Angle Modes
displays a menu to specify the Angle mode as
degrees, radians, or gradients.
displays a menu to specify the Angle unit modifier-
degress ( ), radians ( ), gradients ( ), or DMS ( ). It
also lets you convert an angle to DMS Notation ( DMS).
To set the Angle mode for any part of an entry:
Select the Angle mode. Entries are interpreted and results
displayed according to the Angle mode, or
Select a unit modifier ( ) for any part of an entry.
Entries with unit modifiers are interpreted accordingly,
overriding the Angle mode.
To convert an entry:
Set the Angle mode to the unit you want to convert to.
Then use a unit modifier to designate the unit to convert
from. (Angles of trigonometric functions convert values
inside parentheses first.), or
Select DMS, which converts an entry to DMS ( )
Notation.
Trigonometry
Enter trigonometric functions (sin, cos, tan, sin , cos ,
tan ), just as you would write them. Set the desired Angle
mode before starting trigonometric calculations.
