Setting the Receiver

As receiver units, specify flash units compatible with wireless flash photography using radio transmission.

For instructions on configuring receiver settings, refer to the instruction manual of the flash unit.

Transmission Channel/Wireless Radio ID Settings

To avoid interference with other photographers' wireless systems that have multiple flash units controlled by radio transmission, or with other wireless devices that use radio waves, you can change the transmission channel and wireless radio ID. Set the same channel and ID for both the sender and receiver.

Caution

  • Set different wireless radio IDs for each channel, because interference between systems with multiple flash units controlled by radio transmission may occur even if the units are set to different channels.
