I suddenly experienced a strange issue today - the row of number keys on my 1stPlayer DK 5.0 Lite mechanical keyboard, i.e. the keys from 2 to 9, would output the wrong number! Specifically, hitting all numeric keys in order would output 1678923450 instead of 1234567890. This happened while gaming and I have no idea what caused it.
Factory Reset
A reboot did not solve the problem, nor did fiddling with the keyboard macro app (I tried changing profiles, re-programming macros, removing macros altogether, as well as hitting the Restore button).
After some frantic Google-ing, I found that other people fixed it by resetting the keyboard. On my keyboard this is Fn+Esc pressed together.
Function Keys
1stPlayer do not share their manuals online, in fact their product page has a “User Manual” button that literally does nothing (it’s javascript:void(0)) Since I do not want to go digging for the hardcopy manual again, here are the important keystrokes:
| Keys | Function |
|---|---|
| Fn+Esc | Reset to factory default |
| Fn+Win | Toggle the Windows key (disable and re-enable) |
| Fn+PrtSc | RGB off |
| Fn+Ins | Cycle through 13 RGB effects |
| Fn+Del | Cycle through 8 RGB backlights (depends on selected effect) |
| Fn+1 to 5 | Select a customised RGB colour profile (cancels RGB effects) |
| Fn+ and Fn+ | Backlight brightness |
| Fn+ and Fn+ | RGB effect speed |
| Fn+F1 | Music player |
| Fn+F2 | Volume down |
| Fn+F3 | Volume up |
| Fn+F4 | Mute |
| Fn+F5 | Previous media |
| Fn+F6 | Next media |
| Fn+F7 | Pause / Resume |
| Fn+F8 | Stop |
| Fn+F9 | |
| Fn+F10 | Browser (home) |
| Fn+F11 | Explorer |
| Fn+F12 | Calculator |
Setup customised colour profiles (aka Game Mode)
To set the color on key via the keyboard only:
- Select a profile, by pressing Fn+1 to Fn+5 respectively,
- Press Fn+Home to enter programming mode
- Repeatedly press a single key, and it will rotate through available colours - stop when it is the colour you want
- Repeat for all keys
- Press Fn+Home again to save it under the selected profile 1 to 5.
Unfortunately, it is not possible to create a macro or re-map a key via the keyboard. For that you need to download the keyboard app from 1stPlayer. I have a short usage guide in my 1stPlayer DK keyboard and mouse review.
The app also allows you to set the 5 customised colour profiles. To do so, you have to set the Light option to Game Mode and choose Color Group 1 to 5.
