If any of the batteries are inserted incorrectly, the calculator may not turn
on. If, when you insert new batteries the calculator fails to turn on,
immediately remove the battery holder and check the position of the batteries.
The calculator cannot be damaged by inserting the batteries wrong; it simply
will not function.

If the display blanks out, or the calculator will not respond to keystrokes,
do the following:
|
|
|
|
|

|
Ensure that the batteries are fresh, are properly installed, and that the
battery contacts are not dirty.
|
|
|
|
|

|
Turn the calculator off then back on. If the calculator does not respond.
continue on to step 3.
|
|
|
|
|

While holding the key, turn the calculator
on. This is a ‘‘master clear’’ and the entire
calculator will be cleared. If the calculator does not respond, continue
on to step 4.
|
|
|
|
|

Remove the batteries and let the continuous memory in the calculator discharge
over night. When you reinstall the batteries and turn the calculator on, if
the display shows MEMORY LOST,
you know that the calculator has been cleared.

If the calculator still does not respond, service is required (refer to Limited
