Quick answer
'Reset' can mean four different things on a ZKTeco machine: a simple restart, restoring settings, deleting users or attendance logs, or a full factory reset. Only a restart is harmless. The others can delete fingerprints and records, so back up users and logs to a USB drive or the attendance software first. The options are in the System (or Options) menu and vary by model.
