Logarithms - changing the base
Your calculator can still be used but you need A formula for change of base. Suppose we want to calculate a logarithm to base 2. The formula states.

Calculators don't have a button for calculating a logarithm to any base. They have a button for natural logarithms and a button for logarithms to base 10
Change of Base
6.2 Properties of Logarithms
We apply the Change of Base formula with a = 3 and b = 10 to obtain 32 = 102 log(3). Typing the latter in the calculator produces an answer of 9 as required. 2.

Turning on or off
To turn the calculator on, press [
ON /AC ] ; To turn the calculator off, press [ OFF ].Battery replacement
The calculator is powered by two alkaline batteries (G13 or LR44). When the display dims, replace the batteries. Be careful not to be injured when you replace the battery.1. Unscrew the screws on the back of the calculator.
2. Insert a at bladed screwdriver into the slot between the
upper and lower case then carefully twist it to separate the case.3. Remove both batteries and dispose of them properly. Never
allow children to play with batteries.4. Wipe off the new batteries with a dry cloth to maintain good
contact.5. Insert the two new batteries with their at sides (plus termi-
nals) up.6. Align the upper and lower cases then snap them to close
together.7. Tighten the screws.
Auto power-off function
This calculator automatically turns it off when not operated for approximately 9~15 minutes. It can be reactivated by pressing ON /AC ] key and the display, memory, settings are retained.Reset operation
If the calculator is on but you get unexpected results, press [ ON /AC ] and then [ MODE ] four times to display the below menu. A message appears on the display to con rm whether you want to reset the cal- culator and clear memory contents after pressing [ 2 ]. To clear all variables, pending operations, statistical data, answers, all previous entries, and memory, please press [ 2 ]. To abort the reset operation without clearing the calculator, please press [ 1 ]. If the calculator is lock and further key operations becomes impos- sible, please use a pointed object to press the reset hole to release the condition. It will return all settings to default settings. -E3-Contrast adjustment
Pressing the [] or [] following [ MODE ] key can make the con- trast of the screen lighter or darker. Holding either key down will make the display become respectively lighter or darker.Display readout
