So here’s what happened when I tried to find the NJ80 manual and some legit tips. Total mess at first.
I got this Keydous NJ80 keyboard last week. Plugged it in, started mashing keys, and bam—weird lighting thing happened. Had no clue how to fix it. Figured, “Easy, I’ll just grab the manual.” Thought it’d be right on the Keydous site.

Step one: Official website disaster
Searched “Keydous NJ80 manual” like a normal person. Clicked the first official-looking link. Landed on their support page. Broken English everywhere. No download section, no manuals. Just a contact form buried under product pictures. Filled it out anyway. Got an auto-reply saying “wait 24 hours.” Still waiting, by the way.
Step two: Community chaos dive
Went straight into Reddit threads and keyboard forums. Saw dozens asking about the NJ80 manual. Zero answers. Just people sharing shady third-party links. Found a sketchy PDF site promising “full NJ80 docs.” Nearly downloaded it until my antivirus screamed bloody murder. Nope nope nope.
Almost gave up when I spotted a buried comment on a random forum: “Type the magic words in the search bar.”
The trick that saved me
Opened Google again. Typed this exact phrase: “Keydous NJ80 user manual support resources.” Bing—first result was their actual support portal. Sneaky, right? Had to scroll past three ads and two forum threads, but it finally showed up. Official page, clean design.
Here’s what worked on that page:
- Clicked “Downloads” hidden under the FAQ header
- Selected NJ80 from the dropdown
- Downloaded the PDF manual (v2.3) AND a separate lighting guide
Bonus user tips I actually tested
Since I had the keyboard right here, tried these fixes myself:

- Reset glitchy lighting: Hold Fn + ~ for 5 seconds until spacebar flashes
- Remap media keys: Used their clunky software (remapped volume wheel to zoom)
- Fix Bluetooth pairing: Unplug USB, power switch off/on, hold Fn+Q till it blinks fast
Took two coffees and an hour of fiddling, but finally got the rainbow lights to chill out. Moral of the story? Never trust those shady keyboard reprint sites. Just use those exact search words, and save yourself the headache. Now if you’ll excuse me, my spacebar’s breathing purple again. Cheers.
