REPLACEMENT OF BATTERY FOR MEMORY PROTECTION Time for battery replacement Life of the memory protection battery is approximately 2,500 hours at 25°C(77°F) with the power plug not connected to the socket. * When the memory protection battery is weak, the date/time setting is initialised (1/1/2005, 12:00:00 a.m.). Verify the date/time setting in the date/clock display mode when connecting the power plug to the socket. If the date/time setting is modified or incorrect, promptly replace the memory protection battery with new one. (The life of the pre-installed battery may be shorter than expected because of the time the calculator spends during shipment.) Method of battery replacement Use one lithium battery (CR2032). Caution: Replacing the battery will clear the date and time settings, as well as the conversion rate, and the tax/ discount rate. 1) Turn the power switch “OFF” and unplug the power supply plug from the outlet. 2) Remove the battery cover on the back of the unit. (Fig. 1) 3) Remove the exhausted battery and install one new lithium battery. Wipe the battery well with a dry cloth and place the plus “+” side upward. (Fig. 2) 4) Replace the battery cover by reversing the removal procedure. 5) Press the RESET switch on the back of the unit (See “RESETTING THE UNIT”). After battery replacement • Connect the power supply plug to an outlet and turn the power switch “ON”. Check that “0.” is displayed. If “0.” is not displayed, remove the battery, reinstall it, and check the display again. • Reconfigure date, time, conversion rate, and tax/discount rate. • On the battery replacement date label found on the back of the unit, write down the month and year when the battery is replaced, as a reference for the next battery replacement. Precautions on battery use • Do not leave an exhausted battery in the equipment. • Do not expose the battery to water or flame, and do not take it apart. • Store batteries out of the reach of small children. Fig. 1 Fig. 2 Notas para el manejo de las baterias de litio: PRECAUCION Peligro de explosion si reemplaza incorrectamente la bateria.

The rounding selector should be in the “5/4” position unless otherwise specified. 2. The constant/add mode selector and grand total/rate setting mode selector should be in the “•” position (off) unless otherwise specified. 3. The print/item count mode selector should be in the “P” position unless otherwise specified. 4. If an error is made while entering a number, press or and enter the correct number. 5. Negative values are printed with ‘‘–’’ symbol in red. EL-1197PIII (U1U)-2.

MARKUP AND MARGIN Markup and Profit Margin are both ways of calculating percent profit. – Profit margin is percent profit vs. selling price. – Markup is percent profit vs. cost. – Cost is the cost. – Sell is the selling price. – GP is the gross profit. – Mkup is the percent profit based on cost. – Mrgn is the percent profit based on selling price. Ex./Ej. Cost $200 Sell $250 GP $50 Mkup 25% Mrgn 20% CONSTANT/CONSTANTES 62.35 . 11.11 = 62.35 . 22.22 = 62.35 62.35 62•35 . 11.11 11•11 = K 692•71 . 692.71 22.22 22•22 = K 1,385•42 . 1,385.42 11.11 . 77.77 = 22.22 . 77.77 = 11.11 11.11 11•11 77.77 77•77 = K 0•143 . 0.143 22.22 22•22 = K 0•286 . 0.286 INCREMENTO PORCENTUAL Y MARGEN Tanto la funcion del incremento porcentual como la del margen de beneficio son formas de calcular el beneficio porcentual...
