- Page 2 Safety Warning for Batteries usage ➢ Use only batteries of the type specified in the Specification. ➢ Batteries must be new and undamaged. Carefully check batteries before usage. ➢ To avoid leakage or explosion, always check appropriate battery terminals position (“plus” terminal up) before installing to the TTL Converter.
- Page 3 ▪ The 613-core fiber optical cable type is strongly recommended for usage with TTL Converter, to achieve an accurate automatic TTL flash control. TTL Converter is tuned for 613 fiber cable usage only. Other fiber cables have a lower “transmission index” and give a worse exposure in TTL flash control, and even can be totally incompatible. ▪...
- Page 4 • Note1: Sony camera must be set by menu to the Electronic 1-st curtain shutter type (front e-curtain) for this TTL Converter usage with YS-D3 DUO, because of the processing algorithm inside the YS-D3 DUO strobe. Sony menu setting “mechanical shutter” is not applicable. •...
