3.1.2 Keypad Usage
The keypad provides a flexible method of controlling the functionality of the RC4000. While each RC4000
mode has different requirements for user input, the use of the keypad remains consistent throughout all
modes.
The keypad provides for both specific actions and general data input. As an example, the UP_2_N key
initiates an antenna up movement while in MANUAL mode but also allows for the entry of the number 2
when numeric entry is required or the indication of North when entering a latitude value. The required key
usage is provided in the detailed description of each mode.
NOTE: keypads on earlier RC4000s may not have included the exact nomenclature depicted above.
Keypad usage has remained the same though for all RC4000s.
The following table describes both the specific action and general data entry function of each key.
