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.

Removed screws cannot be reused and must be scrapped! Be careful not to scratch the antenna cover and the frame with the guitar pick! The camera lid has to be opened (1) before the antenna cover is removed from the frame! Open the phone with the guitar pick by starting at pos. 2. It will be easier to insert the guitar pick between the antenna cover and the frame if you at the same time bend the cover slightly upwards with your thumb (3). Gently move the guitar pick along the gap both ways (4) until the antenna cover is loose on all sides. If necessary, do the same thing on the opposite side. Be careful not to damage the antenna cover and the frame as they become separated! Gently lift the cover in the loose end (5) and then slide/wiggle it forward in the arrow direction (6) until it can be removed. K750i & K750c Working Instructions Mechanical 3/00021-1/FEA 209 544/94 B Company Internal © Sony Ericsson Mobile Communications AB 8(42) Antenna Cover continued ASSEMBLY The camera lid has to be open when the antenna cover is assembled to the frame! Place the antenna cover over the frame starting at the top and then snap them together. Check that the antenna cover is properly assembled, i.e. no gaps along the sides! If there still is a gap somewhere, gently press the two halfs together with your fingers! Close the camera lid. Apply 9 Ncm (± 2 Ncm) torque for the screws by using the bit NTZ 112 1052 (Phillips bit)! Tighten two new screws through the antenna cover into the frame.

With the front opening tool, gently release the plastic carrier (not only the metal plate) from the frame. If necessary, do the same thing on the opposite side. Bend/lift (1) the plastic carrier no more than 2 mm. Otherwise it might break and damage may occur to the board-to-board connector (2)! Gently bend/lift the plastic carrier until it becomes free from the PBA using a blunt pair of tweezers (1). Be most careful when removing the keyfoil board-to- board connector with the flexfilm assembly tool! Disconnect the keyfoil flexfilm board-to-board connector by using the flexfilm assembly tool.
