Even when using the DR-1X with an external controller, the COR, analog and digital IDs, TOT, DCS/CTCSS, TX power, etc.
are already controlled by the DR-1X internal control. These internal controls cannot be disabled. The external controller
must not conflict with these functions. Some functions of the internal controller cannot be overridden.
Before connecting an external controller you must make sure which functions are already internally controlled. Special
precautions must be considered when planning to link with external systems.
z Make sure to switch OFF the power to the radio before connecting the cable.
z In case of jamming or interfering signal while in Repeater mode, Pin 1 may be grounded by external control to temporarily
disable repeating the receiver input.
