11.4.3 ADVANCED LOCK FUNCTION
It is possible to selectively lock the keyboard by using the following parameters:
1. brd: select the kind of lock:
a. UnL: all buttons unlocked
b. SEL: buttons UP, DOWN and DEFROST are locked
c. ALL: all keyboard is locked
2. tLC: delay after power-on before activating the advanced lock function
NOTE: when advanced lock function is active, temporary lock and unlock functions are disabled.
11.5 THE ON/OFF FUNCTION
If onF = oFF, the instrument will be switched off by pushing the ON/OFF button. The
“OFF” message will appear on the display. In this configuration the regulation is
disabled. To switch the instrument on, push again the ON/OFF button.
WARNING: any load connected to the normally closed contacts of the relays is always supplied
from the main voltage, even if the instrument is in standby mode.
