As the manufacturing process of the CDM-570/570L has evolved, there have been three different
keypad layouts, as shown in Figure 5-2:

The function of the keypad is as follows:
Key
Function
ENTER
(ENT)
Use this key to select a displayed function or to execute a modem configuration change.
From the opening screen, press ENTER once to proceed to the SELECT: (Main) menu.
CLEAR
(CLR)
Use CLEAR to back out of a selection or to cancel a configuration change which has not
otherwise been executed by pressing ENTER.
From the opening screen, press CLEAR once to proceed to the SELECT: (Main) menu.
Elsewhere, press CLEAR to return the display to the previous selection, or press CLEAR
repeatedly to return to the opening screen.
◄ ►
(Left, Right)
Use these arrow keys to navigate between menu screens. Additionally, use these arrows keys to
move the cursor position (e.g., when editing a parameter value or label character).
▲ ▼
(Up, Down)
Use these arrow keys to navigate from one menu screen’s parameter selection to another.
Additionally, use these arrows keys to edit configuration value digits (numbers) or label
characters (e.g., letters).
The keypad has an auto-repeat feature. If a key is held down for more than 1
second, the key action will repeat, automatically, at the rate of 15 keystrokes
per second. This is particularly useful when editing numeric fields, with many
digits, such as frequency or data rate.
