128 Part F: Configuring Channels © Tait Electronics Limited December 2007Note: When using CTCSS tones, select frequencies that are spreadout across the available range. Do not select tones that are close toone another in frequency, as the tone reject bandwidth may notpermit separating them. For example, if 67 Hz is received, both the 67 Hz andthe 69.4 Hz decoders may operate. The exact select and reject bandwidths vary,see “CTCSS characteristics” on page 93.b. If you want the subtone to initiate a Task Manager action, but not toproduce any audio, change the Action column to display ‘Task Manageronly’.c. In the Encode Signal column, you can tell the base station to transmita different subtone from the one it received.7. In the Tx Timers tab, configure the way the audio, signalling, and carrierend at the end of a transmission.8. In the Advanced tab, configure advanced parameters for CTCSS signalling.9. In the Task Manager tab, define any inputs and actions to customize the waychannels with this profile will respond in different situations.10. Click OK to confirm your changes and close the dialog box. The profileyou defined appears in the Signalling Profiles form.Setting Up a Reminder ToneIf a group of radios using a community repeater are in arrears with theirpayments, you can configure the base station to send out a reminder tone. Ifnecessary, you can disable audio so that they can transmit but not hear eachother.1. Select Configure > Base Station > Signalling Profiles.2. Open the editing form of the signalling profile assigned to the base station’scurrent channel.3. In the row that specifies the decode signal that the group of radios use, clickthe Reminder Tone cell, and select Enabled from the list that appears.When you program the base station with these changes, it adds a remindertone to the transmissions from the group that it re-transmits.Note: To configure the reminder tone, select the Advanced tab ofthe Edit Signalling Profile dialog box.
