Menu Editing Procedure

The IRD possesses 12 menus that display various operational parameters when selected.  Six
(6) of the 12 menus have configurable parameters.  These configurable menus are Program,
RF In, Video, Audio, Remote, and Alarms.  The other non-configurable menus pertain to
Status, Presets, Timers, Data, Configuration, and Save.  Each of the 12 menus can be accessed
by depressing the desired menu key within the 12-button menu grouping located on the front
panel.  Once depressed, the contents of that menu are displayed on the IRD’s front panel
display and modified (if configurable) using the front panel rotary/push edit selector knob.

The following section describes the menu editing procedure.

1.

 

Press the desired 

Menu 

key.  The menu name will illuminate above the

selected menu key and the front panel display screen will display the
corresponding field labels.

2.

 

By rotating the 

Edit

 knob, move the cursor under the field label that is

to be edited.

3.

 

Press the 

Edit

 knob once to enter the edit mode.  The word “EDIT”,

located above the Edit Selector knob will illuminate.

4.

 

Rotate the 

Edit

 knob to change the data for that particular field.

5.

 

Once the desired setting is displayed within that data field, depress the

Edit

 knob once to exit the edit mode.  This will extinguish the word

“EDIT” above the Edit Selector knob.

6.

 

The 

Save

 key, located within the menu key grouping, will now be

illuminated.
