SOURCE: My sharp compet qs-2770h calculator will not let me type in numbers. There is no reset button but there is sequence of keys to press. I cannot remember them. Does anyone???

In some rare occasions, all keys - including the power
key and the key - cease to respond.
If such abnormal conditions are observed, unplug the AC cord from the socket. Keep the unit unplugged for about 5 seconds, reconnect the AC plug, then turn on the power

Why is it stuck on 2?


I wonder if some dirt or liquid got spilt on the keys? I would try removing the case and cleaning at the bottom of the keys. What do you have to loose. Of course, if it is new, I would return it before I attempt a repair.

Good luck.
