If no obvious problem can be found and replacement of the modelling lamp, flash tube or fuses do not effect a cure then it is likely that an internal fault has developed. Always return the unit to an authorised service centre if a fault is suspected after these checks. MIS-FIRE Warning If the unit receives a trigger signal from any of the valid sources (TEST, IR REMOTE, IR TRIGGER, SYNC) but fails to flash for any reason then the display will flash continuously and the sounder will beep (if on). [. . . ] Remove the trigger wire first and then gently pull the tube from its sockets. Replacement is the reverse of removal but ensure that the tube is fully inserted into its socket. Carefully pass the trigger wire through the hole in the trigger tag and tightly wrap the excess around the tag and back up the wire ensuring that it is kept well away from the metal base. The wire may be trimmed back if there is too much excess. 4 13 Esprit Digital 750 Operating Instructions INTERMITTENT Option The preferred mode for the `INTERMITTENT' function can be selected from the `OPTIONS' sub-menu as follows: Option Description Intermittent off. The Modelling Lamp will extinguish while the unit recharges and light again when the unit reaches `READY'. If the unit fails to flash for any reason then the LAMP will not be extinguished. When the unit reaches `READY', after being flashed, the Modelling Lamp will intensify to full brightness and then dim before returning to the previous setting (or to OFF). If the unit fails to flash for any reason then the LAMP will not follow this sequence. Esprit Digital 750 Operating Instructions MAIN CONTROLS & DISPLAY Refer to Fig. 1. The `FUNC' button, the `UP'/'DOWN' buttons and the three-digit display provide a simple means of setting and displaying the main functions. Apart from Bracketing, the unit is designed to retain all settings indefinitely. Switching a hot unit off may also cause the OVERHEAT protection to operate. Default factory setting is di. 7. br. X 1 to 9 FX. X 5. 0 to 10 The FLASH power is adjustable over a 5 f-stop range (6 f-stops) in 1/10 f-stop increments using the UP and DOWN push buttons. The power is displayed in an easy to use decimal form where each whole number represents 1 f-stop. A single press of either the UP or DOWN button changes the value by 0. 1 f-stop (1/10) to give a total of 51 values. If the current value shown is 9. 4 then to reduce the power by 1 f-stop just reduce it to 8. 4. The following table shows the whole decimal numbers and equivalent fractional power ratio: Displayed Power Fractional Equivalent 1 (FULL) 1/2 1/4 1/8 1/16 1/32 (MIN) di. X 1 to 9 F10 F9. 0 F8. 0 F7. 0 F6. 0 F5. 0 FLASH DUMP Option The preferred mode for the `AUTO-DUMP' function can be selected from the `OPTIONS' submenu as follows: Option Description Flash dump off. Always resistively dumps excess energy whenever the FLASH setting is reduced. This method attempts to reduce the power in the shortest possible time whenever the FLASH setting is reduced. The unit determines whether to resistively dump the excess stored energy or to dump it quickly by automatically flashing the unit.

Switch the Infrared Remote Receiver on or off using the `REMOTE' button. `C' - REMOTE CONTROL CHANNEL Display Mode When the IR Remote is switched on the unit will automatically enter the `C' display mode to allow adjustment. The `C' before the displayed value indicates this mode: Display Range X Description Display IR Channel number. [. . . ] When the unit is flashed the Modelling Lamp will extinguish while the unit recharges and will light again when the unit reaches `READY'. The `INTERMITTENT' function in this mode is available whether the lamp is on or off. After the unit is flashed and the unit recharges to `READY' the Modelling Lamp will intensify to full brightness and then dim before returning to the previous setting (or to OFF). The exact effect will depend on the actual lamp setting If the unit fails to flash for any reason then the chosen sequence will not be followed. [. . . ]
