Accessing The Menu

To access the menu enter a valid code and press the ent key. If there are any outstanding system faults, these will be displayed first. Where there is more than one fault a > symbol will be displayed and the scroll keys can be used to view them. Pressing the ent key again takes the display into the menu. The Full Menu or Quick Menu is accessed, depending on the user type.

Note: 1. If the user does not have group choice, all groups assigned to the user code must be unset.

2.If the user has group choice, only the group that the FINAL or ENTRY zone is assigned to in unset.

3.If there are no groups, then the system must be unset.

Full Menu

The Full Menu has a hierarchy of four structures contained within it. Each structure is accessible by an increased user code type.

Quick Menu

The Quick Menu offers users type 2.3 and above a selection of up to 10 options, numbered 0

– 9. The required option is selected by entering the option number (0 – 9) or by using the A > or < B keys to display each option.

The menu options (as with all Galaxy lists) are circular, therefore menu option 9 is followed by menu option 0.

The following Quick Menu options are the factory default settings. Each option is described in the following pages.
