1 Read this first!
After reading section 2 ‘Introduction’ and the first page of section 3 ‘Repair Actions’,
do as follows when a mechanical part needs to be replaced:
•
Search for the part name on the contents page and go to the page number
where the instruction is found
•
Disassemble the phone as far as needed by moving to the instructions stated as
e.g.
Follow the Removal instructions of sections 3.1 – 3.6
•
Carry out the actual repair action as described
•
Assemble the phone by moving to the instructions stated as
e.g.
Follow the Assembly instructions of sections 3.6 – 3.1
(pls. note the reverse order)
When watching the document off-line (after downloading
and extract the ZIP-file), most of the Removal and
Assembly headings are blue-coloured and underlined.
By clicking on such a heading, a Flash Player window
opens, showing a video clip of the actual
removal/assembly.
The flash movie can be controlled from the keyboard by
holding down the Ctrl-key and pressing another key as
follows:
- Start and Stop: Ctrl – Enter
- Rewind to start position: Ctrl – R
- Move one small step forward: Ctrl – right arrow
- Move one small step back: Ctrl – left arrow
If your computer is set up to show Flash movies in an
Internet Explorer window, the movies will most likely be full
size, resulting in poor picture quality.
To shrink the video window to its proper size, drag the
bottom right corner of the Internet Explorer window until
the movie is shown without blurs and edges, which occurs
when the movie window is approx. 12 x 9 cm (indicated by
the red frame in the adjacent picture).
However, it is recommended to have your computer set up
to have the Flash movies played by the Flash Player
application.
When watching the movies on-line as well as off-line, Flash Player ver. 6 or later
must be installed on the computer.
The Flash Player can be downloaded free of charge from
www.macromedia.com
