A meter upgraded to firmware version 4.5.0 or later cannot be downgraded to an earlier firmware
version.
LOSS OF DOWNGRADE CAPABILITY
Failure to follow these instructions can result in loss of firmware downgrade
functionality.
Do not upgrade to firmware version 4.5.0 or later if you need to downgrade the meter in the
future.

Legacy security support

Legacy security support is an interim solution for users that use Standard security mode and is the
default setting for new meters. It provides backwards compatibility with older software
communicating with the meter using ION protocol.

is enabled.
If Advanced security was used before upgrading meter firmware to v3.0.0, Advanced security is
