11.7 KEY LOCK
To prevent misuse of the optical keyboard it can be locked automatically
after 30 seconds by enabling this function.
In battery supplied applications, the backlight can come on each time the
keyboard is activated. As this can quickly degrade the battery, it is advised
to leave the keyboard lock function enabled so that the backlight only
comes on when an optical key is pressed for at least one second. The
keyboard lock function also uses less battery power.
11.8 TAG NUMBER
For identification of the unit and communication purposes, a unique tag
number of maximum seven digits can be entered.
