Radio Shack EC-3031 Calculator User Manual


 
10
Cautions:
You must use an AC adapter that
supplies 6 volts and delivers at
least 300 milliamps. Its center tip
must be set to negative, and its
plug must correctly fit the calcula-
tor’s jack. The recommended
adapter meets these specifications.
Using an adapter that does not
meet these specifications could
damage the calculator or the
adapter.
When you finish using the AC
adapter, disconnect it from the AC
outlet first, then unplug it from the
calculator.
Be sure to turn off the calculator
before you connect or disconnect
the AC adapter.
Follow these steps to use AC power.
