==Explanation==
This was the 11th [[:Category:April fools' comics|April fools' comic]] released by [[Randall]]. The previous fool's comic was [[2288: Collector's Edition]], which was delayed two days and released on Friday April 3, 2020. The next became [[2601: Instructions]] released on Friday April 1, 2022 (a regular release day).

The comic looks similar to a loading screen. The actual comic (this “loading screen”) consists of an animated gif of a {{w|checkbox}} (hence the name). 

The frame is replaced with an interactive panel. In the center is a check box, which clears itself immediately when checked. In the bottom right is a mute button, which begins muted. By unmuting, and changing it to a loudspeaker, sounds are played when the check box is checked. This was the second [[:Category:Comics with audio|comic with audio]] on xkcd. The very similar April Fool's comic from the next year, [[2601: Instructions]], used audio, too. It also had only one element in the center, but not a check box, but a {{w|radio button}}.

Under the checkbox is a scrolling visual representation of the timing and duration of clicks in the check box, which also produce matching beeping sounds when unmuted. The representation consists of a dot for a short press, or a bar for a longer press. All long presses are represented by a bar of a pre-determined length; in other words, a longer press does not result in a longer bar.

By varying between brief and long presses, and brief and long intervals between presses, it is possible to enter characters in Morse Code.

The check box then begins operating by itself, producing sounds which can be decoded as Morse Code. These responses are also printed in the browser's JavaScript console in both plain text and a textual representation of Morse code. If left without any initial input for 30 seconds it would send the message CQ (meaning "Seek You").

The title text hints at the use of Morse Code in the comic; interpreting the "check" as a Morse Code dot and the "chhecck" (a long check) as a Morse Code dash gives ...---..., which is the Morse Code for "SOS", the international distress signal. Incidentally, inputting the SOS signal gives "YOU TOO?".

For the majority of inputs, the check box responds with a random selection from the following list:
* COME AGAIN
* HUH
* NOT FOLLOWING
* SAY AGAIN
* TRY THAT AGAIN
* WHAT

Some keywords, however, have [[#Special Responses´|special responses]].

|XKCD -> FILE NOT FOUND
|[-..- -.- -.-. -..] -> [..-. .. .-.. . / -. --- - / ..-. --- ..- -. -..]
|
|-
|XKCD -> A CROSS THREE LETTERS
|[-..- -.- -.-. -..] -> [.- / -.-. .-. --- ... ... / - .... .-. . . / .-.. . - - . .-. ...]
|A pun on "across three letters", how clues are sometimes given in crossword puzzles. Instead, the word "xkcd" is literally a cross (x), followed by three letters (kcd).
|-
|HI -> HELLO! ANYBODY OUT THERE?
|[.... ..] -> [.... . .-.. .-.. --- -.-.-- / .- -. -.-- -... --- -.. -.-- / --- ..- - / - .... . .-. . ..--..]
|
|-
|HELLO -> HELLO TO YOU TOO!
|[.... . .-.. .-.. ---] -> [.... . .-.. .-.. --- / - --- / -.-- --- ..- / - --- --- -.-.--]
|
|-
|HELP -> ENTER IMAGE NUMBER
|[.... . .-.. .--.] -> [. -. - . .-. / .. -- .- --. . / -. ..- -- -... . .-.]
|See below; if you enter any number ≤ 2445 you will be linked to the corresponding xkcd comic.
|-
|HELP -> YES PLEASE
|[.... . .-.. .--.] -> [-.-- . ... / .--. .-.. . .- ... .]
|Sojourner mistakes the person inputting the morse code as offering help instead of asking for it.
|-
|ES -> QUE
|[. ...] -> [--.- ..- .]
|"Es" means "is" in Spanish, and "Qué" is "what".
|-
|WHAT -> ECHO
|[.-- .... .- -] -> [. -.-. .... ---]
|
|-
|ECHO -> ECHO
|[. -.-. .... ---] -> [. -.-. .... ---]
|
|-
|CHECK -> MATE
|[-.-. .... . -.-. -.-] -> [-- .- - .]
|Checkmate is the winning move in chess.
|-
|CHECKBOX -> RADIO BUTTON
|[-.-. .... . -.-. -.- -... --- -..-] -> [.-. .- -.. .. --- / -... ..- - - --- -.]
|This also works the other way around.
|-
|E (''repeat n times'') -> E (''repeat n times'')
|[.]
|This only applies for n < 7. Also, n=6 returns 'AAAAAA' instead.
|-
|T (''repeat n times'') -> T (''repeat n times'')

|This only applies for n < 7.
|-
|E -> E ''pause'' I -> EIEIO
|[.] -> [.] ''pause'' [..] -> [. .. . .. ---]
|
|-
|I (''repeat n times'') -> I (''repeat n times'')

|Indicates that Sojourner is the operator of the morse code device.
|-
|SOJOURNER -> CFM
|[... --- .--- --- ..- .-. -. . .-.] -> [-.-. ..-. --]
|CFM is short for confirm. Sojourner is confirming that its' in control of the morse code device.

|-
|DIR -> ENTER IMAGE NUMBER
|[-.. .. .-.] -> [. -. - . .-. / .. -- .- --. . / -. ..- -- -... . .-.]
|This references to the next input. DIR stands for directory.

===Rover Scene===
After successfully repairing and rebooting Sojourner, a comic is opened which depicts it seeking out and finding its friends, Spirit, Opportunity, Curiosity, Perseverance, and Ingenuity. Curiosity and Perseverance are locked in a swordfight, and either Spirit or Opportunity is carried off by Ingenuity while the other speeds off a small mound of dirt. Ingenuity carrying a rover is a reference to the previous comic.

==Special Console Commands==
The page's JavaScript creates a global object <code>morse</code> with <code>encode</code> and <code>decode</code> methods.  From the developer console, it is possible to write  <code>morse.encode("A PHRASE")</code>, which will print the Morse code corresponding to the text provided, or <code>morse.decode("... --- ...")</code> which will translate the Morse code to text.

<code>BeepComic.hurryUp()</code> to get the reply immediately in the console.
<code>BeepComic.send(...)</code> to send directly to SOJOURNER.

==Transcript==
:[A small box is in the middle of a large white frame. The box can have a check-mark, but it is alternating between being checked or unchecked. At the bottom right there is a muted speaker (which can be unmuted). If the user press the checkbox gray dots or lines will appear below depending on the length of the press. These will move from right to left and then disappear.]
