This is going to sound super dumb put leave it in a bowl of rice for a couple days. Rice will obsorbe the water. Also, change all five of the batteries(the 4 AAA ones and the back up battery). And if that doesn't work, you're pretty much out of luck. However, don't rush to the store and buy a new calculator. If you're in college or know someone that is in college, do what I do. Go to a math or sicence lab professor and ask them for a calculator at the end of the semester. I'm getting a new 89 pretty soon and i'm kinda excited. Good luck with your calculator

My carrier split ac trip after some time and green light blinking contsly


If this is a ductless split call a tech! The ductless split systems can be a troublesome unit to diagnose. A few things to try. Clean air filters and ensure coil behind is clean. And build up or debris on blower wheel (indoor fan blades) will cause unit to fault. Turn off power at breaker or disconnect and clean (with water hose and medium pressure) the outdoor coil. Be sure you will not damage outdoor coils fins with too much water pressure. Turn power on. If this simple service don't do it again, call a tech! Be sure to ask if they have someone who is experienced with mini split systems and be patient. Even the best technician will need to call carrier for tech support.

Hi, I have a hp50g calc. I was wondering how i can install a formula library from a zip file onto my calc. but more importantly I was wondering if this calc has the functionality to calculate NPV(net...


Unzip it. Transfer it to a Secure Digital card, then plug the card in the SD-card slot. Use the File Manager/explorer and move the library to the Memory location you want.

Replace valve cover gasket on 1998 626 i am worried about tearing up the wiring harness that is over the top of it because its brittle any suggestions?


If there is a segmented plastic sheath (flex split loom tubing) covering a bundle of individual wires and it's the protective tubing that's brittle that's normal. As long as you're gentle when handling it even if some of the tubing breaks off it isn't likely to damage the actual wires. Most auto parts stores sell a variety of split loom tubing that you can use to replace the brittle tubing with. The reason it's called split loom tubing is that it is split along it's length so that it can easily be slipped onto wiring harnesses without even disconnecting terminations.

How do you 'Calc Clean'?


Hello shid9
This is an easy fix. To decalcify your unit you need to make a water/vinegar solution. 2 parts water and 1 part vinegar. You might need to run two pots of the solution through if the first one is very cloudy. When done with that, rinse with 1 pot of fresh water. This should help remedy your calc problem. I hope this is helpful for you.
Happy brewing! NormanZ

How to use the calc-clean button


Calc-Clean function
The Calc-Clean function removes scale and impurities.

To do so, set the steam control to position '0', set the temperature dial to 'MAX', and fill water tank up to the 'MAX' level. Then heat up the iron until the pilot light on the handgrip goes out.

Remove the mains plug from the wall socket and hold the iron horizontally over the sink. Then press and hold down the 'CALC CLEAN' button.

Move the iron forwards and backwards while boiling water/steam squirt from the holes in the soleplate to wash away impurities/scales.

When the water tank is empty, heat up the iron to dry it.

Finally move the iron to and fro on a piece of cloth to dry the soleplate. Repeat the process if necessary

Ti-84 Silver Edition received water damage and cant be switched on


try this :
This works on most mini electronic devices like cellular phones and degital cameras etc .

it sounds crazy .

Remove the back (or Cover ) of the phone( or Camera ), battery, and SIM if your phone ( or Device ) uses one , DIRECTLY
.

Then, with a q-tip (or something similar), dab the connection points (shiny, goldish) on the battery, SIM, and phone. This should aid in drying.

Finally, place all contents in a bag of uncooked rice (separately, do not put back together just yet). it sounds crazy , but it draws the moisture out.

It normally is working after just 7-8 hours, but I would wait 12 hours or even 24 hours before attempting to use (just to be sure).

beware the water damage, despite being dry now, will void any warranties. Also, the phone's hardware is now weakened and if you drop it, the green mother board and circuitry could shatter - so be more careful.


This does work on electronic devices aside from phones as well. Simply tailor it to your device. If you do not have a SIM (Verizon phones, cameras, all others), remove only the battery. If you have an iPhone/iPod or GPS and cannot remove the battery, simply make sure it is all the way off, then put it in the rice bag. All electronic devices react the same to the rice trick.

None of my buttons work except the ON button


Sounds like a possible short to me, But I don't have experience with that cause I have yet to test my calc with water if you know what I mean... The one thing that I can suggest is trying to connect with another persons calc and try the "send OS" command to see if that will reset your calc to a working state. Sorry to hear about the damage though.

Psp and water


you have two possible problems here.

1. there are still water in the console
2. some component burned because of the water.

in the first case (if out of warranty time) open all the psp,clean it and let all components dry for 2 or 3 days somewhere nobody will touch it. and remount and test again.

in the second, you must take it to a technician to take a look and check the possibility to change ir.
