· The EA-200 is made up of precision components. Never try to take it apart.
·Avoid dropping the EA-200 and subjecting it to strong impact.
· Do not store the EA-200 or leave it in areas exposed to high temperatures, humidity, low
temperatures, or large amounts of dust. Low temperatures can shorten battery life.
· Replace the main batteries once every two years regardless of how much the EA-200 is
used during that period. Never leave dead batteries in the battery compartment. They
can leak and damage the unit.
· Keep batteries out of the reach of small children. If swallowed, consult with a physician
immediately.
·Avoid using volatile liquids such as thinner or benzine to clean the unit. Wipe it with a
soft, dry cloth, or with a cloth that has been dipped in a solution of water and a neutral
detergent, and wrung out.
·In no event will the manufacturer and its suppliers be liable to you or any other person
for any damages, expenses, lost profits, lost savings or any other damages arising out of
loss of data and/or formulas arising out of malfunction, repairs, or battery replacement.
The user should prepare physical records of data to protect against such data loss.
· Never dispose of batteries, or other components by burning them.
· Replace batteries as soon as possible after the low battery indicator lamp (Batt) lights.
· Be sure that the power switch is set to OFF when replacing batteries.
· If the EA-200 is exposed to a strong electrostatic charge, its memory contents may be
corrupted or the keys may stop working. In such a case, perform the Reset operation to
clear memory contents and restore normal key operation.
· If you start to experience serious operational problems with the EA-200, use a thin,
pointed object to carefully press the P button on the back of the EA-200. Note, however,
that pressing the P button deletes all data currently in EA-200 memory. Proper operation
does not resume after you press the P button, remove its batteries, and then replace
them correctly in accordance with the instructions on page 0-3 of the User's Guide.
· Note that strong vibration or impact during program execution can cause execution to
stop or can corrupt EA-200 memory contents.
· Using the EA-200 near a television or radio can cause interference with TV or radio
reception.
· Before assuming malfunction of the EA-200, be sure to carefully reread this User's
Guide and ensure that the problem is not due to insufficient battery power, programming
or operational errors.
Handling Precautions
· Never allow foreign objects to get into connector holes. Doing so can result in
malfunction.
·Always make sure to connect probes only to their correct terminals. Never force the plug
of a probe into a wrong terminal connector.
· Be sure to turn the EA-200 off before connecting or disconnecting probes.
· Make sure that probes are connected securely before using them to take samples.
· Never insert a probe into an electric outlet. Never attempt to measure high voltages or
household AC. Doing so creates the danger of electric shock.
· Never apply more than 15V to analog channels CH1 or CH2, more than 5V to analog
channel CH3, or more than 5.5V to the SONIC, DIG IN, or DIG OUT channels. Doing so
can damage the EA-200.
· The EA-200 is to be used for educational purpose only. It is not appropriate for
industrial, research, medical, or commercial applications.

User's Guide (this manual)
About the EA-200
The EA-200 is a digital device that makes it possible for you to sample data connected with
everyday natural phenomena.
Data You Can Sample with the EA-200
Various different sensors can be used with the EA-200 to sample temperatures, light,
voltage, distance, and other data. The EA-200 supports sampling of up to 120,000 points,
and simultaneous sampling over five channels. Sampled data can be sent to a compatible
Graphic Scientific Calculator, where it can be viewed and graphed.
Before Using the EA-200 for the First
Time
Power Requirements
Your EA-200 requires four AA-size alkaline batteries for power. Battery life depends on the
amount of time the EA-200 is left on, and the amount of current used by the connected
probe(s). A low battery indicator lamp (Batt) lights to let you know when it is time to replace
batteries. To extend battery life, it is a good idea to use the AC adaptor for power whenever
sampling indoors.
When using the EA-200 in combination with the optional "Motion Sensor (EA-2)", be sure to
power the EA-200 using its bundled AC adaptor (AD-A60024).
Though the EA-200 can normally operate on battery power, separate AC adaptor power is
required while the optional "Motion Sensor (EA-2)" is being used.
Batteries are not loaded in the EA-200 when it is shipped from the factory. Because of this,
use the following procedure to load batteries into the EA-200 before using it for the first time.
To load batteries
1. Remove the battery cover by pulling with your finger at the
point marked 1. If there are batteries in the battery
compartment, remove all four of them.
2. Load four new AA-size batteries. Make sure that the plus and
minus ends of the batteries are facing in the directions shown
by the markings inside the battery case. Replace the battery
cover.
3. Slide the [ON/OFF] switch to turn on the EA-200. To turn off,
slide the [ON/OFF] switch again.
