Note 1: 10mA per port maximum. Exceeding this limit can damage the microcontroller.
Note 2: These digital output ports are also available in 2500CT model but cannot be used at the same time with the
built in CTCSS decoder. If the decoder is being used and you change a remote output, the frequency of the decoder
will change randomly.
