PTRL-LCD & RXRL-LCD ELETTRONICA 6.2 Operation Switch on the receiver by putting the selector on the position “I” (on) the switch situated on the rear pannel. Enter the menu “Set” and set the working frequency desired. For the description of the different menus. With the help of the switches and trimmers situated on the rear pannel, set the characteristics (deenphasis) and the levels of the audio outputs. From the menu “Fnc”, set the muting mode . 6.
PTRL-LCD & RXRL-LCD ELETTRONICA is indicated on the silk-screen. • Deenphasis: ON 1 ON 1 2 2 6.4 ON OFF Software The machine is provided with a two-line LCD display where a set of menus is shown. An overall view of the machine’s menus is given in figure . One of the following symbols may be present on the left side of the display, depending on the case: _ (Cursor) - The cursor indentifies the selected menu where you can have access.
ELETTRONICA PTRL-LCD & RXRL-LCD When you press twice on the ESC button while you are in the predefined menu, the following selection view is displayed, and from this view it will be then possible to enter to all the other menus: To enter one of the submenus, select the name (that will be enhanced by a flashing cursor) with the RIGHT or LEFT push-buttons and then press the ENTER button. If on the contrary, you wish to return to the predefined menu, you just have to press again the ESC push-button.
PTRL-LCD & RXRL-LCD 6.4.2 ELETTRONICA Set menu (Set) This menu enables to read and set the working frequencies. When you press the ENTER button, it will be possible to modify the setted frequency with the ’UP’ (the frequency increases) and ’DOWN’ (the frequency decreases). After a new frequency value was setted, press the ENTER button to confirm the choice; the exciter will unlock from the current frequency (the LED LOCK switches off) and will lock to the new working frequency (the LOCK LED lits up).
