Motorola XTNID User Manual page 31

To establish proper two-way radio
communication, the channel, frequency, and
interference eliminator codes must be the
same on both radios. This will depend on the
stored profile that has been preprogrammed
on the radio:
1. Channel: Current channel that the radio is
using, depending upon radio model.
2. Frequency: The frequency your radio uses to
transmit/receive.
3. Interference Eliminator Code: These codes
help minimize interference by providing you
with a choice of code combinations.
4. Scramble Code: Codes that make your
transmissions sound garbled to anyone
listening who is not set to that specific code.
5. Bandwidth: Some frequencies have selectable
channel spacing, which must match other
radios for optimum audio quality.
For details of how to set up frequencies and
CTCSS/DPL codes in your channels, "Entering
Programming Mode" on page 38.
