It was a great disappointment and a serious restriction on the practicality of the manual to find that it lacks a convenient and practicable index. The early pages list the various topics in sequence, but these are not indexed with their relevant page numbers . The only means of locating a topic is to do a visual sequential search through the book page by page. Very time-consuming and very disappointing!. Another problem is the small size of the pages - and hence the small typeface sizes which can be difficult to read. A manual I purchased some years ago for a Motorola smart phone was supplied in A4 format, which is much more convenient for reading.
