Wireless Multiple Flash-unit Photography
En-01
• There is no limit to the number of remote flash units that can be used
together. However, when using many remote flash units, light may be
unintentionally picked up by the light sensor of the master flash unit
and interfere with correct functioning. The practical number of remote
flash units for wireless multiple flash-unit photography is 3. In Advanced
Wireless Lighting, for practical purposes, the number of remote flash
units should be limited to around 3 for 1 group.

• Take care not to let light from the remote flash units enter the camera
lens or the master flash unit light sensor for non-TTL auto flash.
• Do not place an obstacle between the master flash unit and remote
flash units as it can interfere with transmission of data.
• When optical control remote mode is set, the standby function is
canceled. Make sure that there is sufficient battery power.
