ON/OFF switch (H). Economy switch (N) (where applicable) used to dim the light output of the lamp and prolong lamp life. Switch should be engaged not less than 30 seconds after powering up projector. Platform release button (F) allows the platform to be opened and access to the interior of the machine for lamp replacement (and fringe control setting on certain 911 models). WARNING - switch off machine and allow to cool before changing lamps or altering internal fringe control settings. Lamp change (L) (where applicable) allows immediate replacement with a second lamp if lamp one should fail by sliding lever/slider across. Fringe control (K) (where applicable) allows the elimination of brown/yellow or blue colouration (fringing) from the edge of a focused picture. Outlet socket (M) (where applicable) is ideal for use with LCD Panels, reducing the number of cables running to the OHP.

If you suspect a blown fuse the procedure for replacement is as follows:1) Switch off OHP at ON/OFF switch (H) and at mains socket. 2) Disconnect the Euro-plug from the Euro-socket. 3) Pull out the fuse drawer (diagram 4). 4) Lift out suspect fuse and replace with another of the specified type. 5) Close fuse holder draw. Reconnect Euro-plug to Euro-socket. The OHP is now ready for use

CLEANING Periodic cleaning of the OHP is recommended as some components may have their performance impaired by environmental conditions. The following procedure should be followed:1) Switch off OHP at ON/OFF switch (H) and at mains socket. 2) Disconnect the Euro-plug from the Euro-socket. 3) Allow OHP to cool. 4) Head unit - the mirror surface (A) should be wiped with a soft, lint free cloth. N.B. - avoid scratching the mirrors surface. 5) The Glass lens should be wiped with a soft, lint free cloth. 6) The top surface of the platforms glass area (G) may be cleaned with a soft cloth and a mild non-abrasive cleaning solution. 7) Fresnel lens - open the platform (G) using the platform release (F). The fresnel lens is the large semi transparent plastic area with concentric circles mounted on the underside of the platform. Press back the retaining clips on one edge of the fresnel lens and lift it out taking extreme care not to scratch the lens surface. Gently clean both surfaces of the lens with a soft, clean lint free cloth. The under side of the platform glass may also be cleaned at this point (refer to 6). Insert the fresnel back into the platform ensuring it is the same way around prior to removal and properly seated.
