Product Identity

The Sharp EL-339HB is a 12-digit desktop calculator built for office and home use. Its extra-large angled LCD display shows punctuation for clear reading. A metal case and kick stand give it a stable feel on the desk. Twin-power operation uses solar energy with battery backup.

Sustained Use

The low-noise keyboard stays quiet during long sessions of data entry. Selectable decimal and rounding switches keep results consistent across repeated calculations. The grand total key accumulates figures without losing track. Independent four-key memory holds values reliably while you work through extended tasks.

Installation and Pitfalls

Place the unit on a flat surface and unfold the kick stand for the preferred viewing angle. No wiring or software setup is required. The only common issue is dim display in very low light if the solar cell receives insufficient illumination; the battery backup prevents total loss of function.

Questions about this item

Does the metal case and low-noise keyboard keep it quiet and cool during all-day use?

The calculator has a metal case and a low-noise keyboard designed for quiet desktop operation, and it runs on twin solar and battery power with no fan or active cooling.

What power source do I need ready for the EL-339HB to work out of the box?

It operates on twin power — solar with battery backup — so no external adapter or separate power supply is required.

Will the 12-digit LCD and cost/sell/margin keys work the same way if I keep using my older Sharp desktop calculator?

The 12-digit angled LCD and dedicated cost/sell/margin keys function independently, so you can run this model alongside any older calculator without interference.
