Safety Information
It is essential to read the following safety information before starting to use
the calculator. Keep this guide close to hand for reference later.
Intended use
This calculator serves exclusively for completing arithmetical processes
indoors. Any other use is considered unintended use.
Batteries
DAfter having removed the batteries from the calculator, keep them in
a safe place so that they cannot get into the hands of small children
who could accidentally swallow them.
DIf a battery is swallowed by accident, seek medical attention
immediately.
DNever charge, dismantle or short circuit the batteries. Do not expose
the batteries to direct heat and never dispose of them in a fire.
DIf the batteries are used incorrectly, the battery acid could escape
causing damage to objects nearby and creating a risk of fire or
personal injury.
DAlways ensure that the positive (+) and negative (-) ends face the
right direction when the batteries are inserted in the calculator.
DRemove the batteries if the calculator will not be used for longer
periods.
DOnly use batteries specified in this guide for this calculator.
DUse batteries must not be disposed of in domestic waste! Please
dispose of them at collection points provided or a special refuse
depot.
Disposal instructions
In order to dispose of your device, take it to a collection
point provided by your local public waste authorities (e.g.
recycling centre). According to laws on the disposal of
electronic and electrical devices, owners are obliged to
dispose of old electronic and electrical devices in a separate
waste container. The adjacent symbol indicates that the
device must not be disposed of in normal domestic waste!
When you dispose of the device, remove the batteries
beforehand and dispose of them separately.
Risks to health and the environment from batteries!
Never open, damage or swallow batteries or allow them to
pollute the environment. They may contain toxic, ecologically
hazardous heavy metals. You are legally obliged to dispose of
batteries at the pointofsale or in the appropriate containers
provided by your local public waste authorities. Take particular

regulations.
Precautionary Measures When Using the Calculator
DIt is essential to press the key before using the calculator for the
first time.
DChange the batteries at least once every three years even if the
calculator is working properly. An empty battery could leak and cause
malfunctions or damage to the calculator. Never leave an empty
battery in the calculator.
DThe battery supplied with the unit could discharge a little during
transport and storage. Therefore, this battery should be replaced
after a shorter period than that stipulated for normal battery service
life.
DLow battery voltage could cause the memory content to be corrupted
or lost. Therefore, always make written copies of important data.
DAvoid exposing the calculator to extreme temperatures during
operation and storage. Low temperatures could cause the display to
light up very slowly, complete failure of the display or a shortening of
the battery service life. Do not place the calculator in direct sunlight,
near a window, near a heater or another location subject to very high
temperatures. Heat can cause the calculator housing to discolour or
warp and cause damage to the internal circuitry.
