OPERATIONAL NOTES
To insure trouble-free operation of your SHARP
calculator, we recommend the following:
1. The calculator should be kept in areas free from
extreme temperature changes, moisture, and
dust.
2. A soft, dry cloth should be used to clean the
calculator. Do not use solvents or a wet cloth.
3. Since this product is not waterproof, do not use
it or store it where fluids, for example water, can
splash onto it. Raindrops, water spray, juice,
coffee, steam, perspiration, etc. will also cause
malfunction.
4. While the memory protection battery is not
installed, the tax / discount rate and conversion
rate set up will be cleared upon terminating the
AC power supply.
The tax / discount rate and conversion rate set
up will also be cleared when the memory
protection battery is removed from the unit.
5. If service should be required on this equipment,
use only a SHARP servicing dealer, a SHARP
approved service facility or SHARP repair service
where available.
6. Do not wind the AC cord around the body or
otherwise forcibly bend or twist it.
