Troubleshooting Guide
Optical Transmission Wireless Flash Photography
Receivers do not re, or mistakenly re at full output.
● When using the ash as a sender, select [Wireless:Optical
transmission] on the camera (p.44). When using the ash as a
receiver, set the channel switch to the same channel as set on the
sender (p.44).
● Make sure the receiver unit is within the transmission range of the
sender unit (p.42).
● Point the wireless sensor of the receiver unit toward the sender unit
(p.42).
● Position the receiver unit at a location with the clearest possible view
of the sender unit.
● If the sender unit and receiver unit are too close, the transmission may
not take e󰀨ect properly.
● When using the camera’s built-in ash as the sender unit, raise the
camera’s built-in ash, and set [Wireless func.] on the camera’s
[Built-in ash settings] screen.
The sender res.
● The sender res even when [Sender ash ring] is set to [Disable],
in order to control receivers optically (p.44).
Pictures are overexposed.
● When using autoash with groups A, B, and C, do not aim ash units
in group C at the subject (p.52).
