One of the number keys (#6) does not function; for example, if I enter a number which includes a 6, the six does not get entered

what might I do to reactivate this key?

thank you

Apply a dry contact cleaner over the defective key and press it many times until it becomes fine if this does not work will.

please follow me:-1- use a *****driver and get out *****s in the bottom(normally 4-5 *****)2-open the machine you will find the keyboard and many small *****s remove all with small *****driver.

3-remove key bad out and clean it with water-dry it carefully and return it back put all *****s back and test your calculator.

To use the power, you use the y to the x key, above the EXP key. To enter 2 to the power of 4, you enter 2 hit the y to the x key and enter 4 and hit enter.

To use percent function, you enter the percent key after the number. To calculate Interest, where Interest = Principal x Interest x Time. For example, if the principal is $1,000, the interest rate is 8%, and time/term is 4 years, we would enter 1000 x 8 Percent x 4. When the8 is entered followed by the percent key, it should turn into 0.08.

Good luck,

It depends on the base of the power function.

**For exponential function** use [SHIFT][LN] (e^x) followed by the exponent value. If exponent is negative use the change sign +/- key before exponent.

For a**general power**, type in the base (number), then press the [Y^x] key followed by the exponent.

For a**power of 10,** use the [Exp] key. Careful here. For example to enter 1.6x10^(-19), type in 1.6, press the [Exp] key, then the change sign key +/- and the exponent. Press [=]

**1 . 6 [Exp] +/- 19 [=]**

Use nPr, which is the shifted function of the multiply key. For example, to find the number of permutations of six items taken three at a time, press 6 SHIFT nPr 3 =

You can select the A (K . A) and then the # of decimal places (F 6 3 2 1 0) you want. So if you want to enter 1234 & it calculates 12.34, this will work.

To enter a power of ten, use EE, the shifted function of the key just above the 7 key. For example, to enter 2 times ten to the 60th, press 2 2nd [EE] 6 0

To raise a number to another, use the ^ key, just to the left. For example, to calculate two raised to the 60th, press 2 ^ 6 0 =

For natural logarithms, you can use the ln function (2ND shift of the X key). For example, the natural logarithm of 3 is 2ND [LN] 3 ) ENTER.

For logarithms to other bases, use the log function (diamond shift of the 7 key). For example, the base-2 logarithm of 16 is diamond 7 1 6 , 2 ) ENTER. If the base is 10 (common logarithms), you can omit the comma and the second argument.

Hi ;

for log base 10 use the the "log" key

example :

log(2) + log(3) = log(6)

enter 2 press the log key you will get 0.30102999 press the '+" key than 3 log you should get 0.47712125 for it Press the "=" or enter and you should get 0.778151250 for a answer than press inv or 2nd log and you should get 6 for a answer

and that all there is to it

probably just need to resolder the switch for #6, should just need to have the soldering iron touch the solder to re melt it. worth a try.
