Will using a Pentax AF240z flash gun on a digital Pentax 1st dl camera cause damage?
it should be fine, the pentax240z flash trigger voltage has been measured at 4.8v
I couldn't find the limit for the hotshoe voltage, but it is most likely very high.
(Canons tend to be low like around 6volts max. my Kodak is 400volts max).
How do theft detectors in stores sense unpaid items?
The most common way now is with a radio tag. It is a tag, sometimes hidden in the package, that sends out a weak signal. If the tag is not turned off at the checkout, it will be picked up by the reader at the front door, and the alarm will go off. When you purchase the item, the salesperson will drag it over a piece of equipment that neutralizes the tag. Sometimes you can hear a noise as it is done and sometimes it is silent.
A common misconception about anti-theft devices is that they are able to detect barcodes on stolen items. This is untrue. Unless the item has a magnetic or radio tag on it, the item will not be detected by the device.
It depends which model you are talking about. The break open type, you break open then look for a small flat spring in the frame in front of the cylinder in line with the axis pin of cylinder this is a spring catch, press into frame and pull cylinder off axis rod. Be careful to watch for another flat spring in the axis rod, this is friction spring for cylinder, do not overlook or lose! The screws in the frames of all models, if the screw does not move, lubricate with a penatrating oil( the very best is KROIL by Kano labs,) strike head of screw with small hammer with light blows and get screwdriver that fits the screws VERY CLOSE, apply down pressure and turn(all screws are right hand threads) if not successful then screws have to drilled out and replaced. These handguns are very simple and OLD. Parts are hard to find some are not to be found. A drawing for some models are on the web at gunpartscorp.com. Good Luck!
How-to check 6o cycle hertz meter?
Hertz is the unit for 1 cycle per second.
So you should know the diameter and how long it takes for 1 cycle.
How can you get a user booklet for a durabrand DBVT1341?
chance are that if there's any chance of finding a uder's manual, you need to go to the Durabrand website and find the manual you need.
If that fails and they don't have a website, you just might want to use a good search engine like Google and just type in the model mumber of your piece of equipment. don't use parenthesis or anything like that. I wouldn't even type the letters in caps either. IF there's anything out there, you should get several returns and then you can choose what you'd like to find.
See.. im not TOO sure. But i guess it is because in India there are really amazing sculptures carved out of cave walls/rocks. Secondly, glacier caves are really beautiful. Its dark and lonely in most caves but you might as well find many bats. Its their habitat. Also, of course, home to many microorganisms. They provide us with adventure,pleasure and entertainment. I guess, these are probably the reasons.. They were home to many prehistoric cavemen also. They are still used sometimes in India as shelters for hermits and religious people. Also, they could be used to make temples.. :) Hope this helped. ++++++ It's a start! All-natural caves in limestone, and lava-tubes, can be beautiful too, and very many are - without anyone carving their walls, too! it's dark and lonely in ALL caves unless you explore them properly, in a team and all equipped with proper lamps! The darkness beyond any penetrating daylight is absolute. caves are also important for carrying water from the hills where it fell as rain to springs - but this is also true of aquifers. Caves can also provide scientific evidence in research into palaeoclimates. to help understand long-term climate change. And they are scientifically fascinating in their own right.
Why is the number 10 an important number?
cause its last number if they have a first they have a last understand
Twitter users often message each other. This can be done by tweeting "@username", or via direct message. However, that does not mean that you will receive a message; ultimately, the answer to your question is just "possibly"
What is the total harmonic distortion of a Bose stereo system?
Harmonic distortion belongs to all amplifiers, loudspeakers and simply all electrical equipment you use. When it comes to audio, the only effect you will hear is a constant resonant low noise if the speakers aren't good at handling harmonic distortion. None of the Bose speakers I have tested so far produce that noise, so you don't have to worry about that.
Because you did not use the voltage switch in Europe you damaged the voltage regulator in the hair straightener. Unlike CD players, and other small electronics (which will not turn on if the adaptor or DC input is incorrect) direct to plug appliances will turn on and over-load or short out. Because your straightener only reaches 86 degrees it is safe to say you over loaded it with 220volts (or more). Because all United States plugs are no higher than 120volts you damaged it by overloading it with at least 100 extra volts.
Bottom line, buy a new one, you won't be able to get this one fixed.
What is an example of frequency?
Frequency can be found in sound, light, and line current. An example of frequency is, the frequency wave of light will determine what color the light is.
What is the relationship between frequency and harmonics?
In digital, there's also usually a sinusoidal oscillator which is either built in or external, but the oscillations are converted into square waves to create a clock pulse which negates the harmonics.
There is a little problem in counting the harmonics and the overtones. So you find different statements in the internet. Some are wrong and some are right.
Scroll down to related links and look at "Calculations of Harmonics from Fundamental Frequency".
TTL Logic Circuits - "Transistor Transistor Logic" - are made using BJTs. They operate from +5 Volts. These are available from simple AND, OR, NAND Gates to complex circuits.
The voltage levels are
INPUT OUTPUT
Low (0) < 0.8V <0.4V
High (1) >2.0V >2.4V
Levels in between are undefined. The outputs are better than the inputs by 0.4V thus offering a noise margin. These are seldom used these days as other logic families have been introduced offering more advantages like, speed, lower power, wider / lower operating voltage, higher fanouts.
Sort of. In Sonic Adventure 2 Battle, he does Chaos Control to flee from that exploding capsule and in the race/battle with Shadow, if you play as Shadow and get to far ahead then Sonic says "I'll use your...Chaos Control" and zips in front. But this is the only game that I know of where he can use Chaos Control.
--
sonic has the power to use chaos control like shadow. However it is far more draining on his energy than for shadow. However the other chaos abilities such as chaos blast and chaos spear do not appear to be available to sonic.
What happens when a PUSH instruction is executed?
The value being pushed (push [value]) is placed on the top of the stack (esp) and the size of the value is added to esp.
What does prefix 74 and 54 on a ttl of cmos ic indicate?
The 74 indicates a general use IC, the 54 indicates a military specification device with a greater operating temperature range. These two prefixes were originally assigned in the 1960s by Texas Instruments for their TTL logic family, but have since become de facto industry standards. They were also adopted for CMOS in the 1980s when it was decided that having common package pinouts would make it easier for both logic designers and circuit board layout software.
You can try turning your squelch up. This will filter some of the static out. You can also program your scanner to only pick up channels that are relatively close to you. This will stop a lot of the static too.
I found the following solution at:

...and it worked!
maybe if you go there you can read better. For Lexmark printers, follow until the very end. NOTE: Dell printers are made by Lexmark and have the same issue!)
How to clean up printer drivers
If the Print Spooler service fails when printing, when Windows starts or it can not be restarted, the usual reason is that one or more printer drivers is defective. If the Print Spooler service is not running, the Printers and Faxes folder will be empty and you can not use it to remove (or add) printers or printer drivers. If you have a Lexmark or Dell printer, see special information about Lexmark printer drivers.
It's important to only install printer drivers that are designed and built specifically for the Windows version you have. This is particularly important for Windows XP; many of the CDs and floppy disks distributed with printers (particularly older models) do not have Windows XP drivers - check the printer manufacturer's web site for printer drivers for the version of Windows you have (see Links).
A common cause of printer driver problems is to upgrade to Windows XP from Windows 95, 98 or ME without first removing the printer and the printer drivers.
The steps on this page will remove all printers and printer drivers from the computer. The printing subsystem is then "clean" and ready for printers to be added using printer drivers specifically for the Windows version you have.
If you have drivers for several printer models installed (e.g. on a Print Server computer) it may only be necessary to remove the defective printer drivers. At steps 2, and 7, just delete the entries for the printers or printer drivers you suspect are defective. Unfortunately, the files that comprise the drivers are all in the same folder. Also, the same files may be used by the drivers for several printer models. So, selectively deleting the driver files at step 12 may be difficult or impossible. With Windows 2000 and XP, in most cases, deleting the registry entries for the drivers (step 7) will be sufficient, so you may want to skip steps 10 through 12 if you have multiple printer models and don't want to re-install all of them.
Check in Control Panel, Add/Remove Programs; if there is an entry relating to one of the printers, select it, then click Change/Remove. Follow the dialog and "uninstall all" or "remove all" as appropriate. Some "printer software" have programs that show up here and it will be a good idea to remove those before going any further.
If the Print Spooler service is operational:
1.
Open the Printers (Printers and Faxes on Windows XP) folder 2.
delete all of the printers 3.
click File, Server Properties 4.
select the Drivers tab 5.
for each entry: 1.
select the entry 2.
click Remove
Usually, this will do a pretty good job of cleaning out drivers with Windows 2000 and later (not so with Windows NT 4).
If the Print Spooler service is not operational, or you want to make certain there are no printer driver remnants, either follow the instructions below or use cleanspl.exe from the Windows 2000, XP or 2003 Resource Kit (http://www.microsoft.com/downloads/details.aspx?FamilyIDen). cleanspl.exe from the Windows 2003 Resource Kit tools will work on Windows XP.
Some information about cleanspl.exe:
*
cleanspl.exe does a very thorough job of cleaning up the print spooler stuff, but it does not remove the spooler service dependency on the Lexmark service (see special information about Lexmark printer drivers. *
You can use it to clean up the spooler stuff on another computer (i.e. remotely). *
When you run it, it asks you if you want to remove some things that are actually delivered (and installed by default) with Windows. In most cases, you should answer No to the corresponding prompts (you don't want to remove the Standard TCP/IP Port or the BJ Language Monitor).
Here's how to clean up the print spooler stuff if cleanspl.exe is not available or you prefer to do things manually.
Warning! be very careful using regedit - if you delete the wrong things, you may render your computer inoperative!
6.
open regedit (e.g. click Start, key regedit and press Enter) 7.
navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Environments\Windows NT x86\Drivers
under this key, there will be the keys Version-2 and Version-3 (one or the other of these may be absent - not a problem)
the sub-keys under these contain the printer driver configuration information
delete all the sub-keys inside Version-2 and Version-3, but not these keys themselves
The Microsoft Knowledgebase article at http://support.microsoft.com/default.aspx?scidkb;en-us;324757). The steps below make the print spooler service only dependent on the Remote Procedure Call (RPC) service (RPCSS), which is normal. The print spooler service dependencies are stored in the registry at
HKEY_LOCAL_MACINE\SYSTEM\CurrentControlSet\Services\Spooler\DependOnService
The sc config command at step 16 resets the value of that entry.
15.
Open a Command Prompt window 16.
key the command sc config spooler depend but not before) 17.
restart the print spooler (see steps 8 and 9 above)
What type of items are considered electric?
Items considered to be electric require some sort of electricity in order for the items to work. These products can range from TVs, stereos, computers - anything that runs from a battery or is required to be plugged in to run correctly.
