Notes: Basic function calculator with one peculiarity. On the back of the calculator it warns against keeping the batteries in when the adapter is used. Apparently the battery circuit is such that the AC adapter’s power is fed to the battery when plugged in. This would probably blow up the battery if left inside.

Identical to the Eltex 300-R.
