LOCK/UNLOCK
Lock is used to prevent unwanted changes to programming. No changes through the front panel or RS-
232 port can be made while the unit is locked. The lock may be initialized in either the “Setup” or “Running”
mode. Once the unit is locked, the operating mode can’t be changed. If unit is locked in “Setup” mode,
“Running” mode can’t be accessed. If the unit is locked in “Running” mode, “Setup” mode can’t be
accessed.
NOTE: Any 5 digit security code (except 00000) may be used to lock the unit. The same 5 digit code must
be entered to unlock the unit. Place the 5 digit security code used to lock the unit in a safe location for
future reference.
