### What does MC, MR, & MS mean?

Hi,

Welcome to Fixya. Heres the meaning that you're looking for.

MC - Memory Clear. this clears all contents of the memory
MR - Memory Recall. This displays the current content in the memory
MS - Memory Save. This saves the current display to memory.

Thanks for using Fixya.

### What does MC,MR,M-,M+ on the calculator mean and do?

Hi,

MR is Memory Recall
MC is Memory Clear
M- is Memory subtract

These are used to add and subtract the answers to multi-step equations so you can do the small steps with the calculator, then store, change or recall the total as needed. You might add a long string of numbers in groups this way. Or you can do all operations in one parenthesis, then just store the total of each.

A good problem to illustrate this would be : (123 x 3) + (55 - 24) + (10^2) - (7 x 8) = ???
Using MR, M+ and M-, you can do each one as a group, and only store the answers. 123 x 3 = 369 so M+ to put 369 in memory. Clear it from the calculator. 55 - 24 = 31, so M+ to put this in memory and add to the 369 already there. Clear it from the calculator. 10^2 = 100, so M+ this to memory also to add it. Clear it from the calculator. 7 x 8 = 56 so M- this to SUBTRACT it from memory. Clear it from the calculator if desired. Now, when you then hit MR, you will get the total of all of these small equations in parenthesis -- 444.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

### I cannot open my pc

This seems to be a typical problem that is affecting the motherboard of the 290. Try to reset the bios using the Jumper J1 situated under the memory modules in the memory expansion bay. Just short circuit the J1 pin with a screwdriver for few seconds and the bios will be resetted. This procedure have been reported to work sometimes. If nothing is changed, then usually substition of motherboard is required.

### Set Tax Rate

First clear all w/ ON/AC.
Enter the tax rate desired eg. 7 for 7% (can you tell I'm in PA)
Press RATE then TAX+
Press C/CE.
The next time you use TAX+ it will calculate and add the value that you set.
Do the same for TAX-, you can use a different value for each as they are separate memories.

### Memory and memory recal

The STO> button just above the on/off button is your memory store initializer.
example: 2x + 53 STO> y
stores "2x + 53" in a variable named "y".
To recall, just hit y and enter. In fact, if you type an equation like 3y^2 - 4y it will insert the data in for every "y" and give you:
(2x + 53)(6x + 155) as an answer.
To clear the memory:
DelVar y or F6 (2nd+F1) and clear all w/ single character names.
To recall a prevous answer, 2nd+(-) or type ans(1) for the last answer. You can also type ans(2) for the 2nd to last answer & so on.

### MEMORY RECALL OK? problem mine is view sonic monitor .from the past one month its showing problems in display.its giving "MEMORY RECALL OK?" and this whether i press any of the two buttons asked for ,is...

From the Users Manual for this monitor: "Memory Recall returns the adjustments back to factory settings if the display is operating in a factory Preset Timing Mode listed in the Specifications of this manual. - Exception: This control does not affect changes made with the User Color control, Language Select or Power Lock setting." When the monitor is asking "Memory Recall OK?" it either wants to initiate a settings Recall, or it's asking if the Recall was successful. In either case, the "Memory Recall OK?" message is supposed to go away when you push either button 1 or button 2. If it does this when you are adjusting settings then it's likely just doing what you told it to, even if you don't realize you told it to do that. It's also possible for one of the settings buttons to be stuck down and this is causing it to try and change the Recall settings. Push each of the buttons on the monitor and pay attention to what each one feels like as you push on it. If one of them feels different from the others, it's likely stuck. Tapping lightly on the settings buttons or on the panel beside them will usually free up a stuck button. If a button is stuck and won't loosen up by tapping beside it, you might need to pry up on the edges of the button VERY gently with the sharp tip of a pointy kitchen knife. If it's doing this when you did not touch any of the settings buttons at all, then this is likely being caused by a dendrite whisker or faulty circuit trace inside the monitor and you'll need to take the monitor to a service technician for repair. But remember to contact Viewsonic first and go to whatever Service Center that they advise, since a repair of this type may be covered under warranty. One other thing you could try before spending money on it is simply to change the Timing mode in the Windows display settings. Go to "Control Panel > Display", then select the "Settings" tab and click the "Advanced" button. Select the "Monitor" tab and change the screen timing to a different Hertz value in the "Screen refresh rate" menu box. Don't forget to save these settings by clicking "Apply" and "OK" to close all of the Windows settings windows. Hope that helps solve your problem...
