Need help interpreting Chinese instructions for a clock

[xrunner]

Might buy this clock kit just to see how it looks/works -

Clock Kit

I downloaded the PDF file instructions, but I'm not sure what they mean in some places. Main thing is where it says in 3 or four places -

"... add "1" as 8 MHz speed".

What's that all about? I take it "long press button" means to press it a long time, but I have no clue what the 8 MHz thing is all about. There's also another place where it mentions "1 MHz"

Here is a small screen shot, and I attached the PDF file. Any help would be appreciated. Thanks.

short press is straight forward.  +1 per press when the sound is on ( guess sound means a beep for every increment)

Long press is +1 at 8 Hz rate when sound is on.   I guess a better way to put it,  is +1 per 125ms.

I only read Japanese but the characters are similar. I think what it is saying is that if you hold the button down the time advances one unit 8 times per second. In other words the increment rate is 8Hz.

Hmmm ... Sounds plausible.

I've noticed another translation quirk - whenever they mean "soldering" they always seem to use the word "welding". Is there no exact Chinese translation for "soldering"?

That has been discussed before.  Apparently there are several languages where they don't make a distinction between "welding" and "soldering".

Hey Richard - I sent you a PM several days ago about something - do you not read your PMs?

Sorry, I missed it.  I'm not much into PMs.
