12. life of the flash tube and the unit as a whole depends on the way it is used Avoiding excessive heat is the key to long life e The fast recycling feature of the VC series allows a rapid sequence of high power flashes 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 10 to 20 minutes without flashing or at a substantially reduced rate This flash is fitted with a cooling fan and will cool faster if left switched on with the modeling lamp off Dimming or turning the modeling lamp off will reduce heat generation Avoid rapid high power flashing when using restrictive reflectors such as snoots or grid reflectors particularly if the unit is pointing downward Do not flash over 12 shots per minute for over 10 minutes Do not flash over 8 shots per minute for over 30 minutes e Take special care when shooting in a high temperature environment In the event of a malfunction the LCD screen will display a blinking error code The WARNING icon will also blink In addition errors codes E2 and E3 have a beep warning Following is a short description of the three error codes and the necessary action to take E1 Temperature Transducer problem Turn the unit OFF immediately and contact the place where you purchased the flash E
