Access Code; Lcd Display Timeouts; Restoration Of Default Settings - ASL INTERCOM VAR4 Operation Manual

2.1.2.1

Access Code

The VAR Router is password protected in order to prevent unauthorised alteration of the system
configuration. Thus the system configuration cannot be changed unless the operator is 'Logged on' by
entering the correct Access Code.
When the operator is 'Logged off' it is not possible to change any configurable items, or to clear any fault
logs. It is, however, possible to view all the system information apart from the access code.
2.1.2.2

LCD Display Timeouts

All menus timeout to revert to the previous (higher) level after two minutes with no user activity. If logged on,
then after five minutes with no activity the user is logged off. Thus with no user activity the LCD display
always returns to the top-level display and logged off state.
The LCD backlight is under control of the processor. It is switched on whenever any button is pressed, and
stays on for five minutes after the last key press has occurred. Should a fault occur, the backlight is
automatically illuminated.
2.1.2.3

Restoration of Default Settings

It is possible to restore all default settings, including the access code, by setting DIP-switches to a special
power-up condition. Details of this procedure are given in
