CRC16 CHECK SUMS
The check sums are formed from the device parameters. In each case, the BT3xx calculates a check sum for the
parameters from access levels 0, 1, 2 and 4. This is displayed as a hex‐adecimal value. The check sums are used to
determine whether or not the value for one or more parameters present in the corresponding access level has been
changed.
