10.17 DIGITAL VOICE OPERATION
Digital voice programmed systems have three (3) different voice modes: clear (analog), digital, and
private (encrypted). The voice modes are programmed on a per-channel basis within each conventional
system.
10.17.1 Clear Mode
The Clear Mode is a voice mode in which the radio transmits and receives only clear (analog) voice
signals. These analog signals are non-digitized and non-encrypted. Clear mode transmissions can be
monitored easily by unauthorized persons.
Channels programmed for clear operation cannot transmit or receive digital or private
messages.
10.17.2 Digital 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.
If receiving an analog I-Call, the radio responds in the analog mode during the hang time.
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.
