Factory special mode
The Factory mode is a special TV working mode intended to help in the manufacturing process and it is identified on the screen with the message �FAC�. This mode is not suitable for customer use. The main differences in respect to normal mode are: 1. Stand-by is always disabled. 2. Blue-back (no sync. signal present) is disabled. 3. Customer adjustments ( volume, contrast ...) work four times faster. 4. �Cosmetic� delays are skipped out. In case of finding the TV set in Factory mode, it must be taken out of this state. To do so, just enter and exit the user clock setting menu.

Automatic channel search reset (P & P)
In order to reset the initial automatic channel search function, start a channel search in AUTO mode from the user tuning menu and switch-off the TV set before any station is found. The next time the TV set is switched on, it will start an automatic channel-search.

Service menu
The service menu is accessed by holding down the front key �VOL-� and simultaneously pressing the teletext GREEN key from the remote control. The service menu is a two level structure as shown in the next page diagram. The active keys (local or remote) in service mode are: VOL-, VOL+, P-, P+, MENU and the digits. The navigation through this menu works the same than in the user menu. * The P+ and P- keys allow to navigate through the options in the active menu. * The VOL+ key opens the second level menu if available. If there is a highlighted adjustment, the VOL- and VOL+ keys allow to change it. * The MENU key goes back one level menu. If the active menu is the main one, it exits the service mode. * The digit keys allow direct entry for adjustments. * The SERVICE mode is exited by pressing any other key.

�HOTEL� and �RENTAL� modes
This two special modes are intended to be used in hotels, hospitals and similar with the purpose to avoid the manipulation of the basic TV settings. They are stored in NVM, so they are kept even though the TV set is disconnected from the mains. Its main features are: 1. Maximum volume level is limited to the volume chosen when the mode is entered. 2. Tuning operations are disabled. 3. The TV set always switches on with the normalisation settings and users can not memorise any of their personal preferences. 4. Language selection and child lock are disabled. 5. It is possible to force the TV set to always switch-on in a selected program between 1 and 8 or in AV1. To activate this mode, hold down the �VOL -� front key and simultaneously press the �RECALL� remote control key. The message � HOTEL: 00 � will appear waiting for two digits entry. The first digit indicates the selected mode: �0�: normal mode �1�: HOTEL mode �2�: RENTAL mode The second digit indicates the program in which the set will switch on: �0�: the same as it was selected when the TV set was switched off (normal mode) �1� to �8�: always this programme selection (1 to 8). �9�: always AV1 mode The �RENTAL� mode has the same features as the �HOTEL� mode and additionally only the Vol+/- front keys are available so it is only possible to change program with the remote control. In order to exit from this mode, the colour saturation level must be set to zero.
