APPLE IPAD MINI 4 TABLET COMPUTER



Apple Ipad Mini 4 Tablet Computer, retail from $399.99 (www.apple.com...)
Manufactured by Apple Computer Co. (www.apple.com)
Last updated 08-12-24



The Ipad Mini 4 computer is a "tablet"-style computer; though primarily an internet machine, it has plenty of ways to use it offline as well.

My primary use of the Ipad Mini 4 will be as an FPV device for my DJI Mavic Mini FPV R/C Drone.

It runs the iOS operating system, and uses Apple Safari as its web browser. It also has a bright and cheery 7.90" LCD display with LED backlighting that gives you up to 9 hours of internet time per charge of its remarkeably slim internal rechargeable battery.

It has a rear-facing camera but is not equipped with a flash.

The online user's manual is right here if you wish.

To turn your shiny new (or corroded old ) Ipad Mini 4 on, press & release the small rectangular button on the upper right edge of the unit (on the top, not on the side).

When the unit springs to life, press the "Home" button located on the front of the unit near the bottom edge at the center. If you did this correctly, the screen should change from the one you see when you first turn the unit on to either the "Unlock" screen or to the "home" screen (the one with all of the icons on it).

The Ipad Mini 4's screen is touch-sensitive; a virtual keyboard is displayed any time the unit requires text input.
You can use either your finger or a stylus to type or launch a program.

To neutralise the unit, press & release the small rectangular button on the upper right edge of the unit (the same one that you used to turn the product on).

The Ipad Mini 4 is rechargeable, so I don't have to tell you which part to remove, throw over the side of the Juneau-Douglas bridge so that it goes blub blub blub all the way to the bottom of Gastineau Channel with all of the bowling balls that were lobbed over that bridge in the 1950s and 1960s, and then rather emphatically tell you not to.

To charge the Ipad Mini 4, take the white cord with a USB connector at one end, plug it into the receptacle on the white "wall wart" for it, plug the "wall wart" into any convenient standard (in north America anyway) 110VAC to 130VAC 60Hz AC receptacle (or, "wall outlet" or even, "wall socket" if you prefer) and plug the small plug on the end of the cord into the female receptacle for it on the lower edge of the Ipad Mini 4.



This is a tablet computer, not a flashlight meant to be thrashed, bashed, trashed, and abused. So I won't try to drown it in the toliet tank, bash it against a steel rod or against the concrete floor of a carport in effort to try and expose the bare Metalmarineangemon - er - the bare Metaltrailmon - um that's not it either...the bare Metalsusanoomon...er...uh...wait a sec here...THE BARE METAL (guess I've been watching too much Digimon again! - now I'm just making {vulgar term for feces} up!!!), let my landlady's big dogs piddle (uranate) on it, hose it down with my mother's gun, run over it with a 450lb Quickie Pulse 6 motorised wheelchair, stomp on it, use a medium ball peen hammer in order to bash it open to check it for candiosity, fire it from the cannoñata, drop it down the top of Mt. Erupto (now I guess I've been watching the TV program "Viva Piñata" too much again - candiosity is usually checked with a laser-type device on a platform with a large readout (located at Piñata Central {aka. "Party Central"}), with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; the cannoñata (also located at Piñata Central) is only used to shoot piñatas to piñata parties away from picturesque Piñata Island, and Mt. Erupto is an active volcano on Piñata Island), send it to the Daystrom Institute for additional analyses, or perform other indecencies on it that a flashlight might have to have performed on it. Therefore, this section of the Ipad Mini 4 Tablet Computer's web page will seem a bit more bare than this section of the web page on a page about a flashlight.
