5.3.13 Anti-theft encoding
The instrument can be protected against theft by using a freely
selectable, four-digit numerical code:
• If the anti-theft code is deactivated, the instrument can be switched
on again and operated after a power cutoff without having to enter
a code.
• If the anti-theft code is activated, the instrument asks for the code
to be input after each power cutoff.
• If the code is entered incorrectly, the instrument is blocked.
• If the instrument is blocked, it must first be disconnected from the
power supply, then reconnected and unblocked by entering the
correct code.
• After seven consecutive incorrect entries, the display reads "NO
ACCESS, CALL SERVICE". In this case only a Precisa service
engineer can unblock the instrument again.
In order to activate the anti-theft encoding, follow the same steps
described for password protection.
5.3.14 Key tone
If the key tone is switched on, a short audio signal is sounded each
time a key is pressed.
NOTE
The anti-theft encoding is deactivated in the factory settings.
The
preprogrammed code
set in the factory is:
8 9 3 7
This code is the same in all Precisa instruments. Therefore, for
security reasons enter your own code.
Keep your
own code
in a safe place.
