(3) When the required frequency or channel number has been keyed in, press Key 13 to enter the
information. If a valid frequency (or channel in Maritime mode) has been entered, the Home
screen is displayed showing the new Waveform Profile and/or operating frequency. The radio is
now ready for use.
(4) If an invalid frequency (or channel in Maritime mode) was entered during this procedure, the
radio remains tuned to the previous settings; neither the Waveform Profile, or frequency are
altered. An invalid frequency may be due to:
 Entering a frequency outside the range of the radio
 Entering a frequency outside of the Selectable Frequency Bands (see page 3-29)
 Entering an 8.33 kHz channel frequency outside the permitted frequency band
 Entering an 8.33 kHz channel frequency in the wrong format (see page 3-19)
 Entering a 12.5 kHz channel frequency outside the permitted frequency band
 Entering a 12.5 kHz channel frequency in the wrong format (see page 3-20)
 Entering an invalid channel number for Maritime mode
 Entering an 8.33 kHz or 12.5 kHz channel frequency in a waveform that does not support
these channel spacings.
Notes:
 If using an offset carrier system, enter the channel frequency, not the actual frequency. The offset
information is stored in the Waveform Profile
 If using 8.33 kHz channel spacing, see the notes on page 3-19 and enter the appropriate Displayed
Frequency, not the actual frequency
 If using 12.5 kHz channel spacing, see the notes on page 3-20 and enter the appropriate Displayed
Frequency, not the actual frequency
