Navigating the front panel menu system
Access via the front panel keypad can be protected by use of a four number “PIN”.
A special “hidden” menu command, KEYPAD-PIN is available to select a PIN of
your choice. If this entry is set to 0000 the pin is not active and access to the setup
menus is granted just by pressing the “MENU” key. Any other number up to 9999
will activate the PIN and before any menu items can be changed the PIN must be
entered. The PIN will remain active during an editing session. Once an editing
session is complete, or at any time during the editing process, pressing the “MENU”
key will reset access and to re-enter edit mode the PIN will need to be re-entered.
Press MENU - this will display the menu screen options. To scroll through menu items press the
(RIGHT ARROW) key. The cursor on the left side of the screen will highlight each menu
item in turn.
TIP: To more rapidly move through the menu items, you can use the (DOWN ARROW)
key. This will page through the screens 4 items at a time. When the screen containing
the item you require appears, you can use (RIGHT ARROW) and (LEFT
ARROW) keys to place the cursor next to the required item.
Menu items can be either string, integer or "special format" items. Dependent upon the type
of item to be edited the menu edit screen will present different formats.
Scroll through the menu items as described above until the cursor highlights the required
menu item
String edits
Press ENTER - the available string choices will be displayed, with the cursor against the
currently selection. Using the (RIGHT ARROW) and (LEFT ARROW) keys highlight the
required selection, then press the ENTER key. The new selection will be stored.

number keys to enter a new value, where applicable to enter a - (minus) sign use the F1 key,
