It looks like it never came with a manual. The Manuals Online site where you only saw the front page is a scammy site and even the model number is incorrect. If the manual was available, this search query would find it.https://www.google.com/search?q=innovera+ivr+16010+%22manual%22Find a similar calculator by Sharp and use that one.Or phone here and ask if it comes with a manual?https://www.usaofficemachines.com/ivr16010-16010-one-color-printing-calculator-12-digit-lcd-black-by-innovera.html..
Yes... it sounds like the charger was defective and fed too much power to the mouse. It has very likely fried the chip on the mouse. Warranty time. (happened to me as well... different device but same symptoms)
press the button on the wireless station then press the button on the mouse it should see it if it doesn't then you may need a new mouse. you can also test the batteries to make sure they have 1.5 v
After plugging the receiver into your computers USB port and making sure you've got good batteries in the mouse you'll need to do two things:
1-Make sure the power switch on the bottom is ON.
2-Press the pairing button next to the power switch just after you press it on the USB plug, if it has one.
Are you sure that the new battery was a good one? If it is ok, change USB slot. If still not working, you've got some problem with USB dongle or the mouse. Generally, "mice", even wireleess are "disposable". If you have warranty, should take it for "service" and they shuld check problem and replace part. If no warrant, your only choice is to get a new mouse.
