I had the same issue.

- Open up the calculator.
- Remove the battery.
- Remove the two screws holding the display section down.
- Carefully pry the button circuit board up and remove it.
- Use an electrical cleaner and lint free cloth to wipe off the button circuit board.
- Re-assemble and test.

That depends on how much gold you have. 24k merely indicates that the gold is pure, without any other substances mixed in. It refers to the purity, not to the total amount. If you have one kilogram of 24k gold, you have one kilogram of pure gold. If you have two kilograms of 24k gold, you have two kilograms of pure gold. If you have two kilograms of 12k gold, you have one kilogram of pure gold and one kilogram of something else.

Why do you want to get out od Degree mode. If you are doing trigonometric calculations, the angle unit is pertinent. If you are not doing trigonometry, it is irrelevant. You say you can cycle through DEG, RAD, GRAD. That is the way to set the angle unit.

**However, there will always be an indicator on the screen (DEG, RAD, or GRAD). **
