TB8100 Service Kit User’s Manual Working With the Channel Table 139Export Lets you save a set of this base station’s channels to a file so that you can importthem into other base stations. See “Exporting Channels” on page 141.Editing a Channel (Default Profiles)When a channel has the default profiles assigned to it, you can edit most of thecells in its table row.To edit a channel1. In the channel table (Configure > Base Station > Channel Table), click inthe row that defines the channel. An arrow appears at the left of the rowindicating that it is selected.2. If desired, click in the Channel Name cell and edit the channel’s name.3. If necessary, alter the receive frequency and the transmit frequency.Note: The Service Kit does not check whether the base station canoperate on these frequencies.For simplex applications, you can make the receive and transmit frequenciesthe same. The base station automatically increases the transmit frequency by25 kHz when it is not transmitting, to prevent desensitisation of thereceiver.Note: You cannot assign a frequency in the range 406.0-406.100MHz. These frequencies are reserved internationally for distressbeacons.4. If the system requires subaudible signalling, configure it as follows:a. In the Receive Signalling column, select the subtone that the basestation will receive.b. In the Transmit Signalling column, select the subtone that the basestation will transmit.5. In the Filter column, select the appropriate audio filter. See “Filter” onpage 116 for more information about the available options.6. In the Output Power column, specify the transmitter’s RF output power.7. In the Channel Spacing column, specify a nominal channel spacing for thetransmit and receive channels. For more information, see “ChannelSpacing” on page 138.8. Click OK to confirm your changes and close the form.Note: If you are editing a large number of channels, periodicallyselect File > Save to save the changes to a file on disk.Editing a Channel (Custom Profiles)If you assign custom profiles to a channel, most of the columns becomeread-only. The channel is largely defined by the settings in the assigned profiles.To edit a channel1. In the channel table (Configure > Base Station > Channel Table), click inthe row that defines the channel. The arrow appears at the left of the rowindicating that it is selected.2. If desired, click in the Channel Name cell and edit the channel’s name.
