In what position should the keypad function for channel programming?

The keypad should be in Program mode for channel programming because this mode is specifically designed to allow users to configure and adjust settings, including programming channels. In Program mode, the device enables the necessary functions and features that facilitate user input and the modification of various parameters related to communication channels. This dedicated mode prevents accidental changes during regular operation and focuses all capabilities on setup tasks, making it essential for accurate programming.

Using any other mode, such as Power on mode, Standby mode, or Operational mode, would not provide the appropriate access or functionality required for effective channel programming, potentially leading to confusion or errors during the process.
