  Mode Settings
       
  The right switch sets the following modes
  • OFF
  • ON without pilot light
  • ON with 100 % pilot light
  • ON with 50 % pilot light
  • ON with 25 % pilot light
  • Slave sensor with 100% pilot light
  • Slave sensor without Pilot light
  • Automatic Signal (for attention)

    In this positions, the following signals are possible and generated automatically:

    1. Pilot light with International SOS signal (3 x short, 3 x long, 3 x short)

    2. Strobe light with SOS signal (3 x short, 3 x long, 3 x short)

    3. Continuous Strobe every 15/30/60 Seconds at Full, -1 and -2 power settings

 

  The strobe can be used as a slave unit (strobe will be activated by a primary strobe) either with or without the pilot light.
The slave sensor is not sensitive to natural daylight, but reacts very sensitively to the sharp light impulses from strobes. This allows the strobe to be used underwater at long distances from the primary strobe.
The 6 manual power settings are available for the slave mode.

A special feature is the TTL slave mode. In this mode, the amount of light which the slave produces is remotely controlled by and matched to the primary strobe!
