Very slow loading but it gives US numbers.

As mentioned in another post 6688 or 3308 may work--also see alot of mentions of 0765.
6688 worked for me, but have yet to find a manual for my sons CKT1427.

If you have a blank screen with a red key on the bottom left, simply press the (function or F) button and the mute button at the same time.

Yeah,this is kinda late, but I joined for this post so I figured I would reply.

If anyone has any luck with manuals, please post.

Thanks for that we have had several enquiries
about this brand and its code setup and its never to late to post an answer because like the Sun rising tomorrow morning somebody else will ask this question again
Even a partial answer does help some people
