How to block the touchscreen feature on Max Lite touchscreen monitor

To block the touchscreen feature hold down the 1717/4x Video Door Phone centre button until the screen with the padlock image appears. The touchscreen is inhibited for 20 seconds, after which it is re-activated. The screen touch functions can be unlocked before the pre-set time by pressing the centre button once again or by following the instructions that will appear on the screen.

The touch feature block is particularly useful when you wish to clean the screen, so as not to activate the Video Door Phone functions.
