TIM 2015 Technical Manual v1 (February 2018)
Page 2
TIM 2015 is part-funded by the Telecommunications Heritage Group (THG) and designed by
WORK IN PROGRESS! A document of this kind is never entirely complete, so once the website is complete (
www.TIM2015.uk
) please
check for a newer version. Thank you for your understanding.
PLEASE NOTE: This is the
Technical Manual. For setting up the clock after completion and information on the various methods of
synchronising the correct time please see the separate
User Manual document. The Assembly Manual explains how to construct TIM
2015.
Document doesn’t print properly?
All TIM 2015 documentation is produced in the DIN A4 format (8.27" x 11.69"), which may cause problems when printing onto US Letter
size (8.5" x 11") paper. With Acrobat Reader for instance under
Size Options
, you will see four options: Fit, Actual size, Shrink oversized
pages and Custom Scale. One of these should work; we would suggest
Shrink oversized pages
, which will normally reduce the scale by a
few per cent and will not be very noticeable.
How to use this manual
This manual is written in something close to plain English and should be easy to follow (if not, tell us!). Yes, there’s a lot of it but you don’t
have to read it all in one session. The text is as comprehensive as possible, simply because not every constructor will be familiar with some
of the tasks.
Important information
is printed in bold type
like this.
Supplementary information
that it is not essential to read the first time around, but could well be of value at a later stage, is printed in
panels (box-outs) with a grey background.
