9.17.2Digital Mode

The Digital Mode allows the radio to transmit and receive digitized voice signals. Digital signals provide improved weak signal performance and cannot be easily monitored with a standard receiver. Groups and channels programmed for digital operation transmit only digital signals. Individual phone calls (I-Calls) are answered back in the mode in which they were received assuming the call or hang time is still active. Individual phone, all call, and emergency calls are transmitted clear if the digital mode is disabled or inoperative.

1.If receiving an analog message trunked call, the radio responds in the analog mode during the hang time on the working channel.

2.If receiving an analog I-Call, the radio responds in the analog mode during the hang time.

3.When using the *WHC* feature to respond to an I-Call (after the hang time has expired), the call is transmitted in the mode defined by the system mode as programmed for the current system if the ID being called is not in the I-Call list. If the ID is in the I-Call list, then the call is transmitted as defined by the I-Call mode programmed in the list for that ID.

The overdial DTMF tones are not available while in the Digital Mode.

9.17.2.1 Scanned Group Calls

Receiving a Scanned Group Call is the same as receiving a selected group call. During the scan hang time, if the radio was programmed for auto-select, it will transmit back in the same mode it received the call. For example, if a clear group is entered in the scan list, it will only receive clear calls. If the same group was available in digital and entered in the scan list, it can receive clear and digital calls, provided auto-select was programmed in the radio. The user can choose to transmit on the scanned or selected group. If a group is entered in the scan list more than once under different modes (clear and digital), only the first occurrence of the group will be used.
