Vivitar DF-383 Camera Lens User Manual


 
This flashgun can perform as a wireless slave by switching the Slave Mode Switch to S position. The
flashgun will automatically switch to M mode with power ratio 1:1. When the sensor detects the
external flash fire, the flash will synchronize to the fire. The amount of light output can be controlled
by selecting the power ratio from 1/1 to 1/16. If multiple flashes are set as slaves, you must consider
the light amount to get the correct exposure. When the slave mode is on, the power saving mode will
not function.
Power Saving Function
The flashgun will automatically be switched to power saving mode 3 minutes after:
• the flashgun was switched on
• the last flash was fired
The LCD Display will show an "OFF" signal. To reactivate the flashgun, simply press any
buttons underneath the LCD display panel or switch the main switch off and on again.
The flashgun is not completely switched off, however its power consumption is
drastically reduced. If you are not going to use your flashgun any longer, set the main
switch to "OFF"
