Type System command
Syntax LOCK(code)
UNLOCK(code)
Description The LOCK command prevents the program from being viewed, modified or
deleted by personnel unaware of the security code. The lock code number is
stored in the Flash-PROM. The UNLOCK command allows the locked state
to be unlocked. The code number can be any integer and is held in encoded
form. LOCK is always an immediate command and can be issued only when
the system is UNLOCKED.
LOCK and UNLOCK are available from within Trajexia Studio, users can
select LOCK and UNLOCK commands from the Online menu.
Arguments • code
Any valid integer with maximum 7 digits.
Example >> LOCK(561234)
The programs cannot be modified or seen.
>> UNLOCK(561234)
The system is now unlocked.

be recovered.
