3) When I have a manual in foreign language, which is frequently, I use google translate.http://translate.google.com/#
How to use google translate for timer manuals:
a) Enter entire sentences into translator and it recognizes the language. Then select language you want to translate into. Then press translate button.
b) Copy-paste translation into a document so you can read the information several times while working to set timer.
c) With patience, you can figure out the timer, and then change your document wording so you have digital copy of manual for your records.
