Manual is very general

The clock itself is top! Looks really good and is also very good with vepackt protectors. It is a pity the manual. The manufacturer several types of clocks are described, but not those. What the left-bottom button is, I have found only by trial and error. Thus turning the scale ring! But what does this graduation? Get me the manufacturer ekundigen what this part of the clock is to use it. Let's see what I can get the answer, and if I get a manual for the TERAMO DT1029-C ..... Actually, this clock has earned five stars, the missing star is due to the peculiar manual !!!

Had had contact with the manufacturers and have also received an immediate response in the form of an e-mail with two links. The scale ring is a circular "slide rule" !!! The manual was the same with you! I can recommend the clock and the service without further notice! Tip to the manufacturer: DC all descriptions lay in the package !!
