The HERO4 Black camera is compatible with 4GB, 8GB, 16GB, 32GB
and 64GB capacity microSD, microSDHC and microSDXC memory
cards (sold separately). You must use a microSD card with a Class

memory cards for maximum reliability in high-vibration activities.

Slide the memory card into the
card slot with the label facing the
front of the camera.
When fully inserted, the card
clicks into place.
NOTICE: Use care when handling memory cards. Avoid liquids, dust
and debris. As a precaution, power off the camera before inserting
or removing the card. Check manufacturer guidelines regarding use
in acceptable temperature ranges.
