Radio Shack EC-3031 - Manual (Page 10)

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.
