3.2.6 The Enter/Cancel Key
The [ENTER] key is located below the up and down arrow keys on the right side of the keypad. This key is similar to
the Return or Enter key on a standard PC keyboard. It is used to choose/accept a selection or confirm an operation.
For example, after locating and displaying a parameter within the Perfect Harmony menu structure, the operator may
use the [ENTER] key to edit the parameter’s value. Common functions of the [ENTER] key include:
• Selecting a submenu
• Enter edit mode for a selected parameter value
• Accept a new parameter value after editing
By using the [SHIFT] key, the [ENTER] key can be used as a cancel function. The [CANCEL] function is used to
abort the current operation or return to the previous menu display. Common functions of the [CANCEL] key include:
• Returning from the menu system
• Rejecting any modifications to a parameter value in edit mode
3.2.7 Shift Function Keys
The [SHIFT] key is located in the bottom right corner of the keypad on the Perfect Harmony system. This key is used
to access a second set of functions using existing keys on the keypad. Keypad keys that can be used with the [SHIFT]
key have two labels (one on top and one on the bottom of the key). The standard (un-shifted) function of the key is
listed on the bottom half of the key and has a white background. The shifted function of the key is shown on the top
of the key and has a green background (matching the green background of the [SHIFT] key to identify that they are
used together).
When the Perfect Harmony prompts the operator for a numerical value (e.g., during entry of the security access code,
parameter modification, etc.), the [SHIFT] function of numerical keys 1 through 6 changes from quick menus to
hexadecimal numbers “A” through “F” respectively. Refer to Table
3-2 for more information.

Common functions of the [SHIFT] key include:
• Entering “speed menus” ([SHIFT] plus appropriate “speed menu” key from main meter display).
• Using the [CANCEL] function ([SHIFT] + [ENTER] sequence).
• Entering hex values “A” through “F” ([SHIFT] + [1] through [SHIFT] + [6] when editing values or entering
security code).
• Accessing menus, parameters or pick lists based on ID numbers ([SHIFT] + [D].
• Returning to the top of the current menu/submenu ([SHIFT] + [×]).
• Going to the bottom of the menu or submenu ([SHIFT] + [Ø]).
• Resetting the current security level to 0 ([SHIFT] + [A] + [SHIFT] + [A]+ [SHIFT] + [A] from the main
meter display).
• Setting a parameter value back to its factory default ([SHIFT] + [A]).
A summary of [SHIFT] key sequences is listed in Table 3-2.
*
Note: It is not necessary to simultaneously press the [SHIFT] key and the desired function key. The
operator must press the [SHIFT] key first, release it, and then press the desired function key. When the
[SHIFT] key is pressed, the word “SHIFT” appears in the lower right corner of the interface display
(indicating that the Perfect Harmony is waiting for the second key to be pressed). After a key is pressed,
the word SHIFT is removed from the LCD. Refer to Figure
3-5.
