I suffer from hearing loss badly. I've had three different Sennheiser headphones over the years so I can listen to the TV at a level good for me without it blasting for the rest of the House. The ones I have currently are HDR 170 they are AWESOME! Can adjust bass treble as well as volume up and down but they are very comfortable over the ear headphones. Their best feature is the way they sound. Man you won't be disappointed especially listening to music through these. They're great! Cordless, rechargeable, long playing too. I get about a good 12 hrs out of a chargecould get more but want them for the night. Hope this helped. Go to a store that sells them if you can maybe Best Buy etc. try em out. Then shop for cheapest price as they're not cheap.

you can remove the right protection from the computer you use to create the right protection, if you want to use diferend computer that's impossible but same you can go to start and type CMD the comand prompt once the (CMD) folder will open, type (discpart) another (CMD) folder will open type list disc that is going to highlight all the disc on your computer or laptop, now type select disc and exact number of the flash drive if it's 1 2 or3 and hit enter it will select exact number with the flash drive, now attribute clear readonly and enter, now it will says attribute successfully, now type exit to see changes remove the flash drive and plug it back done

There is quite a lot of "that depends" in the answer.

That depends on how long you need to run the pump, whether it to be run in short bursts with long gaps or long bursts with short gaps or run continuously. That depends on whether any battery charging is carried out while in use, solar for instance.

That depends on whether the 1/4 hp is the input of the motor or the output. Some motors are rated one way and some the other. If the motor output is 1/4 hp, the input has to be more due to the relative inefficiency.
If the motor input is the equivalent of 1/4 hp the output will be less and it might be your motor might not be able to do the work adequately or for long enough.
A 1/4 hp input motor will consume 1/4 of 746 watts
A 1/4 hp output motor will consume 1/4 of 746 watts X the motor inefficiency, say, 130% which is a consumption of almost 250 watts.

That depends on the efficiency of your inverter.
Inverters aren't particularly efficient though great leaps forward have been made in this over early models, the inefficiency can't be ignored.
If the inverter efficiency was 100% the 250 watts the motor requires will require a current flow from the battery of about 21 amps but allow a notional inefficiency of the inverter similar to that of the motor that becomes around 27 amps.

There can be no definite answers until those questions are answered and it is best to provide wide safety margins to allow for falling battery capacities as they age. It is also best to assume the rated battery capacity is half of the actual due to the efficiency quickly falling off after the terminal voltage has fallen to half charge.

These understandably are rough figures. A fully charged battery of 100 AH (amp hour), considering the desirability of not allowing the battery to fall below half charge, will power the pump continuously for around two hours. Running the motor in bursts can extend the time considerably.

The batteries will need to be traction or deep cycle types rather than vehicle batteries but even such batteries will suffer a shortened life if the recharging is not carefully managed - frequently topping up the charge level of a partially discharged battery is infinitely more desirable than a less frequent complete recharge.

I hope this helps...

It sounds like the file format of the pictures does not show up in your device. If it has settings to let you see "all" files, then they will show up. If you have a computer what is on the sd card will show up there. That will also tell you the file format of the pictures. You could also change the format to one that can be used by whatever device you want to view them in, using photo editing software.

try parallel .
negative battery one to negative battery two
positive battery one to positive battery two
all positives to inverter positive
all negatives to inverter negative

Why ?
if batteries are in series you are adding voltages so inverter gets 24 volts when it is rated at 12 v to 16v but two batteries in parallel increases the current available and capacity but keeps voltage at 12 v

You will have to be the computer administrator to change any values on any hard drive

click start control panel user accounts you should see a box with the administrator and the guest account if


you have made one click on the administrator this may vary depending on which operating system you have


click start click to open on my computer you should see your usb drive E: right click select properties there will be an array of options


select the security tab option then advanced make sure you have full control in windows 7



click start click to open on my computer you should see your usb drive E: right click select properties there will be an array of options select the sharing tab option then advanced sharing make sure you have a tick in the share this folder box then click permissions make sure you have all 3 boxes ticked full control changes and read in windows 7


click start control panel user accounts click on the administrators account if you have made one or you will have to create one in windows XP

click start right click on my computer select open
Right click the icon of your usb drive (It should be E:/ or something)
Click Properties in the menu that comes up
Click the Sharing tab
Click permissions
And finally, click Allow next to Full Control.


hope this helps you
