Parameter Changes and access

Please note that the RVT is fitted with some locking function, independently than the administrator rights.
– MODE: the RVT must be in SET Mode to allow parameters settings modifications.
– LOCK SWITCH: the lock switch have to be released
– BANK SETTINGS: the parameter Bank Settings must be set to Unlocked.
– The parameter COMMUNICATION LOCK is used to add an access level to users. When locked, all parameter set-
tings modifications (except the Communication lock item setting) from the RVT touchscreen are forbidden. Param-
eters may meanwhile be modified by the communication access only (provided all others access levels are ful-
filled).
