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.

NOTE: 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 .
