MARK-UP CALCULATION (MU)
The basic use of the Mark-Up (MU) key is identical
to using the % key to add a desired margin
percentage to the input number.
A complex use of the Mark-Up key is to calculate a
desired margin percentage based on the result of
the calculation (as opposed to the input number).
The following examples will both use a desired
margin percentage of 15% to illustrate the
difference between the two uses of the Mark-Up
calculation.
Example 1 (Mark-Up % based on input number):
Press Result
ON/AC 0
100 X 15 MU 115
{100+15%=115; however, 115-15%=97.75}
Example 2 (Mark-Up % based on result):
Press Result
ON/AC 0
100 ÷ 15 MU 117.647058823
{100+15%=115; however, 117.647058823-15%=100}
BATTERY REPLACEMENT
The primary power for the calculator comes from
the solar cell; however, the backup battery will
provide power for low light conditions. Erratic
readings, a faint display, or no display are all
indications that the backup battery must be
replaced. Remove the battery cover, located
on the back of the unit. Remove the exhausted
battery and replace it with a new AA alkaline
battery. Make certain to insert the new battery
with the proper polarity as indicated by the
illustration in the battery compartment. Replace
the battery cover.
