While the external flash is connected, the following icons are displayed.
∫ Using a external flash by connecting with a flash synchro socket
• You can use an external flash by connecting a synchro cable
with a flash synchro socket. The socket has a lock screw to
prevent the cable falling off.
• Remove the flash synchro socket cap by turning in the direction
of the arrow.
• Be careful not to lose the flash synchro socket cap.
• The flash synchro socket has no polarity. You can use a synchro
cable regardless of its polarity.
• Use the flash with a synchronization voltage of 400 V or less.
• Do not use the synchro cables with the length of 3 m (9.8 feet) or more.

• Signal-flashing with wireless flashes is also disabled.
When using other commercially available external flashes without
communication functions with the camera (DMC-GH4)
• It is necessary to set the exposure on the external flash. If you want to use the external flash
in Auto Mode, use an external flash that allows you to set the aperture value and the ISO
sensitivity to match the settings on the camera.
• Set to Aperture-Priority AE Mode or Manual Exposure Mode on the camera and then set the
same aperture value and ISO sensitivity on the external flash. (The exposure cannot be
compensated adequately due to the change on the aperture value in Shutter-Priority AE
Mode and the external flash cannot control the light adequately in Program AE Mode
because the aperture value cannot be fixed.)
