5.1.2 Keypad

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
ENTER
(ENT)
CLEAR
(CLR)
◄ ►
(Left, Right)
▲ ▼
(Up, Down)
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.
