Protecting presets from being overwritten
You can use the
LOCKED
column to protect any lines in the preset
table from being overwritten. The write-protected lines are color-
highlighted in the preset table.
If you want to overwrite a write-protected line with a manual touch
probe cycle, confirm with
OK
and enter the password (where
password-protected).
NOTICE
Caution: Data may be lost!
Lines that were locked with the
LOCK / UNLOCK PASSWORD
function can be unlocked only with the selected password.
Forgotten passwords cannot be reset. This means that locked
lines would be locked permanently. The preset table would thus
no longer be fully usable.
Prefer the alternative
LOCK / UNLOCK
function

CHANGE PRESET
