The modelling lamp on the Gemini R and Pro range features
a 'lamp saver' function; this allows the modelling lamp to dim
if no adjustments are made or the unit hasn't flashed for a
specified amount of time.
The length of time for the 'lamp saver' function to activate can
be set from 1 to 99 minutes in 'user set-up' mode (see page
5 for 'user set-up' mode and options).
Photocell
The Photocell is a built-in light sensitive trigger that allows the
unit to be fired from an external flash source.
The 'CELL' switch on the rear of the unit (see page 4) allows
the Photocell to be switched on or off.
If the switch is set to the 'lower' position the cell will be turned
'on', setting the switch to the 'upper' position will turn the
Photocell 'off '.

three different plug-in trigger modules that are available for
the Gemini R and Pro range are:
• Bowens Pulsar Radio Trigger System.
• PocketWizard Radio Trigger System (344Mhz and 433Mhz
