- Voice Activation Sensitivity: If using voice-activated recording, experiment with the sensitivity settings in different environments to ensure it captures desired sounds without triggering on background noise.
- Password Security: Utilize the password protection feature for sensitive recordings. Remember your password, as there might not be an easy recovery option.
