Status Indicator (LED)
• In stand-by, the Status light is off.

• It turns red briefly when the shutter is released.

Access and Visibility
In a studio situation, and especially when the camera is on a tripod, a good-quality full Canon
E-TTL cord can be used to move the C-TX off-camera to a more accessible position.
