The generator will now recharge for an overexposed frame, which is indicated by the ready lamp lighting up for longer periods.

Shoot the second frame

The generator will now recharge for an underexposed frame, which is indicated by the ready lamp lighting up for shorter periods

Shoot the third frame

The generator will now recharge for a normal exposure, and so on.

Turn the MASTER control towards the arrow each time new light readings are made.

When more than one generator is involved in autobracketing and all generators have been set up and prepared, the sequence is initiated by pressing the ready lamp button of the generator where the sync cord is connected. If unsynchronised flashing occurs on any generator, adjust by first disconnecting the lamp cable and then press the ready lamp until the ”right” blinking rhythm is obtained.

Automatic Safety Functions

If the generator overheats for any reason a protective system will automatically start up. The generator’s recharging intervals will slow down and eventually the recharging will stop com- pletely. After a while, when the temperature has decreased sufficiently, the generator will start recharging at a normal pace. This automatic protection will only start up under extreme conditions when the air vents are blocked for some reason. Due to the fast recharging, in TURBO [14] mode, at ”exceptional” recharging speed (energy turnover) sensitive parts of the equipment, such as the flash tubes are protected, by lengthening the recharging time.

PLEASE NOTE: The air vents of the generator must never be blocked or covered in any way. Never store your flash equipment in a car on a hot and sunny day. Never use a generator that is placed inside a case or transport box. Avoid storing the generator close or below the freezing point, which can lead to loss of capacity (flash output) and risk of condensation when used in a warmer surrounding immediately. Do not expose any flash equipment to wet or humid environments or extreme electro-magnetic fields.
