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.
Setting the sender's transmission channel and wireless radio ID
Set the sender's transmission channel and wireless radio ID as follows. Set the same
channel and ID for both the sender and receiver. For instructions on configuring receiver
settings, refer to the Speedlite instruction manual.
