Carry out the following checks to eliminate any external causes. [. . . ] The flash tube is very delicate, avoid unnecessary handling of the glass tube. Always switch off and disconnect from the supply before changing the flash tube assembly. FAST RECYCLING OPERATION As with any flash unit the useful life of the tube and the unit as a whole depends on the way it is used. Avoiding excessive HEAT is the key to long life. The fast recycling feature of the Esprit Digital allows a rapid sequence of high power flashes to be obtained. However, this feature should be used sparingly since continuous rapid flashing can cause overheating and subsequent damage to the flash tube and possibly the internal electronics. Rapid sequences of flashes should always be followed by a reasonable cooling period, at least 10 to 20 minutes is advised either without flashing or at a substantially reduced rate. The unit is equipped with overheat protection, not to limit performance but to prevent damage under abnormal operating conditions. Repeated operation of the overheat protection should be avoided by decreasing the flash power or repetition rate. Dimming or turning the modelling lamp off will help prevent overheating. Whenever possible, avoid rapid high power flashing when using restrictive reflectors such as a snoot or grid reflector, particularly if the unit is pointing downwards. The table below shows maximum number of flashes permissible at various flash rates and flash settings before allowing the unit to cool. When these are first selected the appropriate display will be automatically selected for checking or adjustment. If the `FUNCTION' or `UP'/'DOWN' buttons are not pressed within 4 seconds then the controls and display will automatically return to the default `FLASH' function. Use the `FUNCTION' button to reselect if required. Functions likely to require less frequent adjustment are accessible via an `OPTIONS' sub-menu. This allows the user to customise certain functions without complicating the main controls. INTERMITTENT Option The preferred mode for the `INTERMITTENT' function can be selected from the `OPTIONS' submenu as follows: Option Description NORMAL. Only available when the LAMP is switched ON (PROP, IND or 100%). 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. Available with the LAMP either ON or OFF. 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). The exact effect will depend on the current lamp setting. [. . . ] Switch the Infrared Remote Receiver on or off using the `REMOTE' button. IR Remote Control is enabled when the associated LED is lit. `C' - REMOTE CONTROL CHANNEL Display Mode When the IR Remote is switched on the unit will automatically enter the `CHANNEL' display mode to allow adjustment. The `C' before the displayed value indicates this mode: Display Range X Description Display IR Channel number. Use `UP' or `DOWN' to select. INTERMITTENT Button This feature uses the Modelling Lamp to indicate that the unit has flashed correctly and recharged to `READY', it is in addition to the normal indication. [. . . ]
