3. If necessary, alter the receive frequency and the transmit frequency.
Important: Do not assign a prohibited frequency to the transmitter.
For example, 406.0-406.100 MHz is reserved internationally for
distress beacons.
For simplex applications, you can make the receive and transmit frequencies
the same. The base station automatically shifts the transmit frequency by
25 kHz when it is not transmitting, to prevent desensitisation of the receiver.
Note: The Service Kit does not check whether the base station can
operate on these frequencies.
4. Click in the Signalling Profile cell. An arrow appears at the right of the
cell. Click it and select a profile from the drop-down list. This list contains
all the profiles defined in Configure > Base Station > Signalling Profiles.
Note: You can use Task Manager instead of the channel table to
select signalling and channel profiles. See TN-1154-AN for details.
5. If you selected the Default profile, you can edit the Receive Signalling and
the Transmit Signalling cells. If you selected a custom profile, these cells
are read-only; they display what has been defined in the profile. To change
them, you must select a different profile or alter the current profile’s settings.
6. In a similar way, select a channel profile.
7. Click OK to confirm your changes and close the form.
Note: If you are editing a large number of channels, periodically
click OK , and then Save .

channel in the block has its own frequency pair, but all other configurations are
the same. You can subsequently edit any channel as desired.
1. Select Configure > Base Station > Channel Table.
2. Click in the row of the channel that you want to block copy.
3. Click Block Copy . The Block Copy dialog box appears.
