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 =

Refer to the vehicles user guide to ascertain hiden codes provided exclusively to the owner and operator of the vehicle. However, Usually computers that have only six number pads may have one of the button performing dual functions. For example, unless there were a menu button on the vehiclel stereo to control settings to acheive zero in place of one of the numbers, a press of on of the six numbers should produce a second funcion as zero figure. However, unless that the vehicle has been replaced with another stereo device still expecting the same features of only six number required from a new stereo having seven key functions. Inquir about the vehicles authentic stereo parts may have been replaced soon after acquisition from manufactuer.

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.
