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.If service should be required, use only a SHARP servicing dealer, a SHARP approved service facility or SHARP repair service.

5.Do not operate this unit with the insulation sheet attached; the insulation sheet prevents the battery wear while shipping, and can be found on the back of the unit's body. If the insulation sheet is not removed, the previously set date and time, as well as the tax rate information will be cleared as soon as the AC power is accidentally unplugged.

6.Do not wind the AC cord around the body or otherwise forcibly bend or twist it.

SHARP will not be liable nor responsible for any incidental or consequential economic or property damage caused by misuse and/or malfunctions of this product and its peripherals, unless such liability is acknowledged by law.

USING THE CALCULATOR FOR THE FIRST TIME

First, pull out the insulation sheet for the memory protection battery (installed for retaining the date/time/tax rate information). Reset the calculator to initialize the unit’s state, then adjust the date and time before using the calculator.

Removing the insulation sheet, and resetting

1. Pull out the insulation sheet for the memory protection battery.

2.Press the RESET switch located on the back of the unit. (See “RESETTING THE UNIT”.)

POWER SWITCH; PRINT / ITEM COUNT MODE SELECTOR:

 

 

 

“OFF”: Power OFF

”: Power ON. Set to the non print mode.

“P”: Power ON. Set to the print mode.

“P•IC”: Power ON. Set to the print and item count mode.

1)For addition or subtraction, each time is pressed, 1 is added

to the item counter, and each time is pressed, 1 is subtracted.

The count is printed when the calculated result is obtained.

Pressing of , clears the counter.

2)When the grand total/rate setting mode selector is in the ON position (GT), the counter will count the number of times that the

calculation results have been stored in the grand total memory.

To print and clear the count, press the key.

3)The memory item counter will count the number of times that the

key has been pressed in the addition.

Note: Each time the key is used in the subtraction, 1 will be subtracted from the count.

The count is printed when the memory is recalled.

Pressing of the key clears the counter.

Note: The counter has a maximum capacity of 3 digits (up to ±999). If the count exceeds the maximum, the counter will recount from zero.
