8.8.3 ProVoice Digital Mode

ProVoice digital mode allows the radio to transmit and receive digitized voice signals. These digital

signals provide improved weak signal performance and they cannot be easily monitored with a standard

receiver. Groups and channels programmed for ProVoice digital operation transmit only digital signals.

Private calls cannot be received or transmitted when the radio is in ProVoice digital mode because the

radio does not know the cryptographic key used.

Message trunked group calls and individual calls will be answered back in the mode they were received,

assuming the call or hang time is still active. Individual, phone, all and emergency calls will be

transmitted clear if digital mode is disabled or inoperative.

• If receiving an analog message trunked call, the radio will respond in analog mode during the hang

time on the working channel.

• If receiving an analog I-Call, the radio will respond in 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 will

be 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 will be transmitted as

defined by the I-Call mode programmed in the list for that ID.

DTMF

The overdial and hot keypad features for transmitting DTMF tones are not available while in ProVoice

Digital Mode.

ERROR Messages

If any of the following error messages are displayed, the radio was either programmed incorrectly or

needs servicing:

DSP ERR

ERR=xxxx DSP ERR DIGV ERR

Power Up Only

If the ProVoice circuit board is not responding correctly, one of the following error messages will be

displayed and the radio needs servicing:

HARDWARE

ERR= 3X

3X will be a number between 30 and 38

8.8.4 ProVoice Private Mode

ProVoice private mode allows the radio to transmit encrypted messages and receive clear or private

transmissions. The radio will transmit private if the group/channel is programmed for private operation

and forced operation is pre-programmed.

If the radio was pre-programmed for auto-select, the radio will transmit in the following modes;

• If Private mode is enabled, transmissions are always in private mode.
