Card handling comes before card formatting
Turn the camera off before inserting the card. When a card needs formatting in the camera settings, transfer the media first; preparing recording space should not discard the only copy of an earlier shoot.
The capacity limit, FAT32 format and U3-or-higher requirement belong together. Checking only one of them leaves the card preparation incomplete.
A compatible microphone is a separate purchase
The manual permits a compatible external microphone sold separately; it does not certify arbitrary microphones or adapters. Verify the exact accessory rather than turning a general support statement into a universal fit claim.
The camera’s battery is built in and rated at 1050 mAh. That is a battery specification, not proof of recording endurance with a particular microphone connected.
