Troubleshooting
Battery does not recharge:
The SciPlus battery may fully discharge after a month or more of inactivity. Simply plug in the calculator as
if to recharge, for about half an hour. Next, perform a reset by inserting a paper clip into the small hole on
the underside of the calculator, and gently push until you hear/feel a small click. Then keep the calculator
plugged in at least overnight to fully recharge.
If a reset does not resolve the problem, determine whether it is an issue with the USB charger or cord by
attempting to recharge with another USB charger and /or cord.
SciPlus calculator is acting erratically:
Perform a reset by inserting a paper clip into the small hole on the underside of the calculator, and gently
push until you hear/feel a small click.
The SciPlus has no sound:
The SciPlus-3500 is designed to be used with earbuds or speakers. There is no external speaker. Refer to
“Speech Output” to ensure the sound is turned on and set to the proper volume. If there is still no sound,
check to ensure you are using working earbuds, and that any volume dial on the earbuds is turned up.
