Power-Zoom

Automatic control of the motorized zoom

When using zoom lenses that transmit their focal widths to the camera, the camera forwards this information to the flash unit. Then the flash unit automatically adjusts its zoom position. The automatic reflector control of the motorized zoom is possible with cameras that permit the digital transmission to the flash unit.

The LCD display on the flash unit indicates zoom positions of 24-28-35-50-70-85 mm. When the flash unit is switched on, the zoom is activated and the position is set at 35 mm. As soon as the camera’s release is touched only slightly, the focal width of the flash unit is automatically adapted to the focal width of the lens.

Whenever the flash head is not at the normal setting (pointing forwards) whereby it is in another position, the zoom position clicks to 50

mmand is indicated in the LCD display by a short flash in the Auto mode.

Manual Control of the Motorized Zoom

With the “Zoom” button, you can alter the reflector position of the zoom independently of the focal width of the lens. The LCD display then indicates “M” and the current setting of the reflector’s zoom position.

Light tapping of the “Zoom” button changes the zoom position in this order: 24-28-35-50-70-85 mm.

Auto Zoom position: 24, 28, 35, 50, 70, 85 mm zoom.

Receiver Function

This flash unit can be operated as a wireless receiver by setting the switch “Slave Mode” to the S position. The flash unit switches automatically to the M mode with an energy ration of 1:1 and a focal width of 24 mm. When the sensor discovers the release of an extreme flash, the flash is released simultaneously. The quantity of the light emission can be selected by setting the energy ration from 1/1 to 1/8. If several flash units are used as receivers, then the corresponding quantity of light must be

taken into consideration in order to calculate the correct lighting. If the reception mode is activated, the energy-saving mode does not operate.

Energy-Saving Function

To save electricity, the flash unit automatically switches off approximately 3 minutes after it has been switched on or since the most recent flash was released. The LCD display indicates the “OFF” signal. To reactivate the flash unit, simply press any button switch below the LCD display table or switch the main switch off and back on. The flash unit is not full switched off in the energy-saving function setting, but its energy use is drastically reduced. When you are no longer using the flash unit, set the main switch to “OFF”.

Safety Instructions

Never use a flash in direct proximity to the eyes of people or animals. This can damage the retina and even lead to blindness.

Only use energy sources specified in the usage instructions.

Never attempt to open or short-circuit batteries. Never expose batteries or rechargeable batteries to increased temperatures such as intensive sunlight or fire.

Always switch off the flash unit before changing the batteries.

Do not attempt to open the flash unit, as it is under high voltage. There are not parts inside the flash unit that can be repaired by the user. In the event that the flash unit is damaged to the extent that internal parts are exposed, then the flash unit may only be used again after it has been repaired. Remove the batteries so that it cannot be used unintentionally.

Never attempt to repair the flash unit yourself. In the event of problems, contact our Customer Service.
