Keyboard CoolerMaster CK530's Missing Manual

I have a CoolerMaster CK530 mechanical keyboard, which I love. It might have come with a small printed manual, but if it did, I no longer have it, and I'm failing to find one online. Here's are some things I've gleaned from experimentation. If there's a manual I've overlooked, or if you have corrections, let me know.

The Quickstart guide provides a list of key strokes, but no explanations. I've reproduced the table here, with tweaks for understandability, and added more descriptions below.

Select a mode
fn + F5 Cycle modes.
fn + F8 Demo (automatically cycles through modes).
Tweak mode
fn + F1 Cycle 8 color variations of the current mode.
fn + F2 Red level 0-9.
fn + F3 Green level 0-9.
fn + F4 Blue level 0-9.
fn + F6 Foreground color. (See below.)
fn + F7 Background color.
fn + Up Faster.
fn + Down Slower.
fn + Left Forwards.
fn + Right Backwards.
fn + F10 In "custom" mode, define color of each key.
Profiles
fn + Esc Default profile
fn + 1 Profile 1 (see mnemonic "P1" - "P4" on sides of these keys)
fn + 2 Profile 2
fn + 3 Profile 3
fn + 4 Profile 4
fn + r Reset current profile to default appearance. (Hold 3 secs.)
fn + e Reset all profiles to default appearance. (Hold 3 secs.)
Macros
fn + F11 Record a macro
fn + F12 Delete macro
fn + PrtSc Single
fn + ScrLk Infinite loop
fn + Pause Repeat
Media
fn + Ins Play / pause
fn + Home Next track
fn + Del Stop
fn + End Previous track
fn + PgUp Volume up
fn + PgDown Volume down
Lock
fn + F9 Cycle unlocked(off) / lock windows key(red) / lock whole keyboard(green)


Many of these are self-explanatory. For the rest:

Using modes

fn is the "coolermaster" key, on the bottom row key between right Windows and right Ctrl.

When holding fn, several keys might light up, depending on the current mode:

  • ESC/1/2/3/4 - one of these keys flashes white to show which profile (see below) is currently in use.
  • If the current mode allows you to select a color to use, then F2/F3/F4 will light up to show the currently selected color's levels of red/green/blue.
  • If the current mode allows two colors to be set (foreground & background), then one of F6/F7 will flash white, to show which is currently affected. (See below.)

Pressing fn + F5 cycles through:

Mode Foreground . Background . Reactive.
1. All off
2. Static (all one color)
3. Rainbow wave
4. Crosshair
5. Reactive fade
6. Custom (see below)
7. Stars
8. Rain
9. Color cycle
10. Breathing
11. Ripple
12. Reactive punch
13. Arcing
15. Fireball
16. Tornado (color spin)
17. Reactive tornado
18. Water ripple
19. Snake


Modes marked "reactive" react to keypresses. Mostly this lights up a pattern around the pressed key. In the case of "snake", you can play using the arrow keys.

Foreground & background colors

Many of the modes have a foreground effect that you can change the color of. For example, in the all-one-color mode (officially called "static") you can select the color with which all keys are lit, using fn + F2/F3/F4.

Some of the modes also have a second color, the background, that you can set separately. You can see if a mode offers this by selecting the mode and holding fn. If this mode offers two settable colors, then either F6 or F7 will flash white, to show you which one you are currently setting.

Press fn + F6/F7 to choose foreground or background, then use fn + F2/F3/F4 to set it.

Custom mode

Custom (mode #6 above) lets the user assign a different color to each key.

  1. First, cycle through modes using fn + F5 until you reach custom mode. It can be tricky to identify when you've reached it. Use the list of modes above to help.
  2. While in custom mode, press fn + F10 to edit key colors.
  3. Select a color using fn + F2/F3/F4.
  4. Press all the keys you want lit in the selected color. Pressing the same key again turns it unlit.
  5. Repeat steps 3 & 4 for other color/key combinations.
  6. Finally, save to your current profile (see below) by holding fn and pressing your current profile key (whichever of Esc/1/2/3/4 is flashing white.)

Some wrinkles:

I can't manage to set a color for the FN key itself, which always appears unlit in this mode.

The caps lock key is unlit in this mode, unless caps lock is on. Similarly, scroll lock seems to always be unlit for me in this mode, although it is lit in other modes.

When you try to assign a color to whichever one of Esc/1/2/3/4 is lit white, to indicate the active profile, then nothing visible happens, but it is working. You have to save (step 6 above). Then you can see whether you successfully assigned the color, or pressed the key one too many times and left it unlit.

While editing key colors, if you wait, without exit/saving, pressing nothing for a minute or so, then key color editing times out, cancelling all your changes since step 2.

Profiles

There are five "profiles", each of which can be used to save the current state of the keyboard.

The profiles are accessed using fn + 1/2/3/4/Esc. Esc is the "default" profile. Current keyboard settings (e.g. illumination mode and customized colors) can be saved to one of the five profiles, and then loaded back later. Are macros stored in a profile? Don't know.

The current profile is shown when you hold fn, by one of 1/2/3/4/Esc flashing white. While keeping FN pressed:

  • Pressing the flashing profile key will save the keyboard state to your current profile.

  • Pressing any of the other profile keys will LOAD that profile, losing the current keyboard state.

Hence, to save changes to an arbitrary profile, you need to select that profile before making the changes.

When turning the keyboard on (ie. plugging the USB cable into a computer), the active profile will be whichever one was last active.
