If no obvious problem can be found and replacement of the modelling lamp, flash tube or fuse does 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. [. . . ] Then insert the umbrella through the hole in the Wide Angle Reflectors mounting bracket and lock in position with the knurled screw. Note: Take care when fitting and removing reflectors/accessories not to damage the flash tube assembly. 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. 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 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.

This allows a quick channel check to be made whenever a channel number is unknown. The remote control can then be switched to that channel. UP & DOWN Buttons Select the required `FUNCTION' as detailed above. Single presses of the `UP' or `DOWN' buttons will increment or decrement the value by one. [. . . ] The resistive dump will continue to reduce any remaining energy while the unit is off. This safety feature cannot be disabled. LX. X 5. 0 to 10 If no adjustment is attempted within 4 seconds then the display will revert to the default `FLASH' mode. If the value needs to be reviewed or adjusted later then use the `FUNCTION' button to select the `LAMP' mode. The LAMP 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. [. . . ]
