The printer provides a printout of your calculations but does not count them.
The printer is on and an item count of additions and subtractions to or from
the register is printed when sub-totaled or totaled.

The GT position controls whether or not the totals from the independent add

press 2 0 2.
An error condition occurs when any number is divided by zero. An overflow condition occurs when an
accumulated total or result has more than 12 digits to the left of the decimal point.
IN CASE OF DIFFICULTY
Be sure the power cord is properly connected and the POWER switch is set to PRT. If the
¦
calculator still does not power-up, try a different wall outlet.
If you are getting calculation errors or if the calculator does not respond to keyboard entries:
¦
1. Press 2 0 2. The display should be 0.
2. Check the switch settings. The most common positions are:

3. Turn the POWER switch off for 10 seconds, then on and try the calculation again.
If you are getting a faint printout or none at all:
¦
1. Be sure the POWER switch is set to PRT, IC, or GT.
2. Check the ink roller for proper installation and sufficient ink supply. Replace or reinstall as
indicated.
