Before upgrading, confirm what firmware version is currently on the recorder:
o If firmware is 1.3.2.5 or lower
	- Please do not attempt to upgrade on your own. Contact Support for detailed instructions on how to upgrade the recorder firmware. Failure to properly update the recorder may result in un-repairable damage to the recorder. 
o If firmware is 1.3.3.7
	- Upgrading to the latest approved firmware will set all recorder settings back to default. Please contact Support for detailed instructions on how to upgrade to the approved version without losing recorder settings.
o If firmware is 1.3.3.12 or above
	- You may proceed with upgrade to the latest approved version of firmware. If your recorder was using a customer NTP server setting before the update, the setting will be reverted. You will need to apply the customer NTP server setting after the update completes.
