Notes: The Monarch is a plain calculator with square roots, percentages and memory. It is quite thin.

There's an ON/OFF sliding switch and also an "ON/C"-key. The latter can be used when the calculator has switched itself off after a certain period of idle time. The content of the calculator's memory is lost however.

Its display shows a dot at the bottom right to indicate the state of the batteries.


A power adapter.
