Disabling The Keypad - Crowcon IR Display Installations-, Bedienungs- Und Wartungsanleitung

2.4 Disabling the keypad

The key-pad can be disabled if required by changing the position of the jumper on the
PCB (see Figure below).
By default, the jumper on the PCB will
be set with one hole on the centre pin.
In this position, all keys and menus are
fully enabled.
Place the jumper over the centre and
right pins and there will be no response
from any key press. The keys will not
beep, nor will there be any way to turn
on the backlight.
Alternatively, if the jumper is placed
on the left and centre pins, the menus
cannot be entered. The Up and Down
keys will work normally and pressing
the Enter key will turn the backlight on
and generate a beep.
